Augustinus Bader Launches Vegan Formulation of The Rich Cream | Review – Allure

By daniellenierenberg

While The Rich Cream is not the first vegan Augustinus Bader product (The Lip Balm, The Face Oil, The Essence, The Cleansing Balm, and The Body Oil have that designation as well), the upgrade features what cofounder Augustinus Bader (a famed stem-cell scientist) describes as "an advanced and smart formula resulting in deeper nourishment and hydration and, overall, a more immaculate complexion."

As a fan of both original and upgraded The Rich Cream versions, I can attest to that statement. The rich, buttery formula sinks in quickly and keeps my dry, stressed skin intensely hydrated overnight and well into the next day. "We merge a deep respect for nature and biology with knowledge-fueled targeting of skin repair needs," Bader tells Allure. "Now that our Rich Cream is vegan, it's an added bonus it is the ultimate sign of respect for nature." Another piece of exciting news: The brand says it's working on becoming entirely vegan.

The non-vegan ingredients cut from the formula include lanolin and beeswax. King (who is not affiliated with the brand) explains that lanolin is derived from wool grease and can cause long-term sensitivity and allergic reactions for some people. You also won't find lactic acid (a type of alpha hydroxy acid or AHA) in the upgraded formula, which King says is most likely created from fermented milk, and, therefore, not vegan.

On the flip side, the brand added moisture-binding hyaluronic acid, irritation-soothing hydrolyzed rice protein, and sisymbrium irio seed oil which, according to King, promotes cell turnover, firms the appearance of skin, and even helps reduce eczema. And despite the upgrades, this version keeps the essence of the original, fan-favorite The Rich Cream intact and for good reason; it works. Associate clinical professor of dermatology at Yale School of Medicine, Mona Gohara, counts herself among the legion of The Rich Cream's fans. "It's packed with peptides, a Trigger Factor Complex (which helps skin cells regenerate), vitamins [like panthenol, aka, vitamin B5], shea butter, and squalane," she praises, likening it to the cake and icing of skin care.

Seven Innovative Skincare Brands That Deliver Clinical Results – Forbes

By daniellenierenberg

I find it hard to stay in the loop these days. When it comes to new consumer productsespecially in beauty, it seems like there is a new brand coming out daily. As a natural skeptic, I can be leery of new things.But, I rounded up seven innovative skincare brands that deliver clinical results that are definitely worth exploring.

Eskafil

Eskafil

Due to recent buzz, particularly in the K-Beauty space, snail slime as a hero ingredient may have popped up on your radar. But like so many trends, they are rooted in something much older. In fact,Hippocrates used to prescribe the mucusto clear up skin inflammation while small, rural communities used it to hydrate skin and to alleviate acnes and calluses.

In the spirit of its traditional use in skincare,Eskafilwas created in fall 2020. Founded by Jeffrey Lee and Marius Ronnov, Eskafil is a dermatologist-crafted beauty line of highly effective skincare products packed with ingredients found in nature. We are brand that revolves around the power of natural ingredients, in our case snail slime, Ronnov tells me. We believe ourselves to be gatekeepers of natures secrets and stewards of self-care. To us, skincare is self-care and we work to inspire our customers to commit to themselves everyday, with something as simple as a skincare routine.

Ancient Greeks coined snail mucin as the fountain of youth due to its ability to stimulate new cell repair and increase collagen production, the protein responsible for young healthy skin. What makes snail mucin so effective is one of its active ingredients, allatonin. It is this substance that repairs the snails shell when it accidentally becomes chipped or split. So just imagine what it can do for your skin, especially if you suffer from scarring caused by acne or from eczema, states Lee. The extract's healing properties are also known to heal cuts, soften scar tissue, fight infections, repair sun damage, regenerate skin cells and make skin look younger, tighter and brighter. Recognizing its hydrating properties and skin healing abilities, we wanted to introduce this miracle ingredient to users in the Western world.

Eskafil

Eskafils three-step skincare rangeis easy to use, packaged beautifully, and effective. After a few weeks of use, my skin definitely looks brighter. I would imagine this is due to the high levels of snail mucin concentrate in the products, which is 98%. I havent used eye creams in years since many of them felt heavy and often congested my eye area. But I love the way this light formula instantly cools and hydrates my eye area. It feels like you have nothing on your skin. We pride ourselves on using dermatologist-approved formulas that take supporting ingredients such as macadamia oil, shea butter and golden seaweed to enhance the healing nature of snail slime, explains Ronnov. This combination of ingredients across our products drives hydration, acne scar repair, reduction of fine lines and protection against signs of aging.

If you are wondering if any snails got injured in the whole process, the pair tells me that what makes their brand stand apart from the other snail slime products is there ethical sourcing. We obtain the snail slime through a system that places snails in an environment that makes them extremely pleasured and happy, Lee tells me. This environment is a room thats at the exact temperature and darkness for ultimate snail happiness. The snails then excrete their slime over a mesh covering then the slime is removed and placed into Eskafils skincare products.

Heraux

Heraux

Launched this past spring byAmir Nobakht MD, MBA, and Ben Van Handel, PhD,two of the top leading researchers on the topic of inflammaging,Herauxoffers a paradigm shift in skincare.

Inflammaging is the aging process that is attributable to chronic, low-grade inflammation in our bodies, explains Van Handel, PhD, who is a stem cell biologist at the University of Southern California. Inflammaging is actually caused by things like oxidative stress and environmental damage. These stressors cause our body to release inflammatory molecules, which harm the cellular environment and result in the visible signs of aging. Inflammaging specifically is what happens when this inflammatory process stays active on our body over a long period of time due to stressors like the environment, sun, and even our diets.

It is important to reduce chronic inflammation because once you have it Van Handel, PhD tells me your body just creates more inflammation. Thats how our cells work; by releasing some inflammatory molecules into our systems other cells respond by releasing more as well and the cycle, if left unchecked, continues. When we treat the inflammatory component of these conditions, we stop that cycle and allow the cellular environment to improve so our cells, including stem cells, can regenerate and function at an optimal level, continues Van Handel, PhD.

Heraux is the worlds first anti-inflammaging skin care product.It is the only skin care product to address inflammaging, Nobakht MD, MBA tells me. We are a science forward skincare brand that uses proprietary molecular technologies to improve our skin by combating the negative effects of inflammaging which is the aging caused by everyday chronic inflammation. Unlike most skin care products that only treat the symptoms of medical issues like acne, rosacea and the visible signs of aging,Heraux Molecular Anti-inflammaging Serumgets to the root of the problem by modulating the inflammatory pathway in the skin.

Heraux

The serum is the brands first product release and is based on HX-1, a proprietary biomimetic lipid the pair discovered while researching arthritis for over a decade. Van Handel, PhD explains to me that the lipid is a major breakthrough in the fight against chronic inflammation and skin aging. This revolutionary one-of-a-kind molecule shields stem cells from the effects of stress and promotes their overall youthful function by modulating the protein that regulates regeneration versus inflammation. The lightweight formula also hashyaluronic acid, peptides, vitamins C + E, and red maple bark extract included to make it a well rounded face serum.

The formulation itself is patented, continuesVan Handel, PhD. Themain benefits includea reduction in wrinkles and fine lines, improved skin texture, increased brightness, reduction in hyperpigmentation and increased skin elasticity, all of which have been verified by an independent clinical trial. Results are seen in as little as 1 week with continued improvement with extended use. When I ask if there will be any other products to follow Nobakht MD, MBA responds, We are looking to launch a spot treatment version for acne and hyperpigmentation as well as a sunscreen very soon.I really like the way my skin feels and looks from using this product for the last few weeks. My vascular rosacea has definitely calmed down. A sunscreen would be a welcome new addition.

Pour Moi Skincare

Pour Moi Skincare

Skincare brandPour Moiwas created based on the premise that regardless of age, ethnicity, or gender that our skins appearance is affected by our exposure to daily, local weather. Founded by Ulli Haslacher, the company officially launched in 2020 (after a soft launch in 2017), shortly after receiving its first patent, with a second one issued a few months later, and several more on the way.

Climate-Smart Pour Moi is the worlds first climate-based skincare brand, changing everything you think you know about skincare, Haslacher tells me. Our brand offer products that are specifically formulated for six global and seasonal climates considering how each climates distinctive range of humidity, temperature, air pressure and light profoundly impacts the look and feel of skin. They are not created in the traditional way to only manage visible symptoms of aging skin. But rather scientifically designed to counteract the major cause of an aging complexionthe climate that you are in!

Not only did Haslacher change the approach to skincare based onclimate research, she even changed the way her products were tested. During R&D our formulas were not just tested in a controlled lab environment but tested on actual people in climate chambers, mimicking different climatic conditions and sudden changes to these conditions, explains Haslacher.

While each formula is based on one of six climate types, Haslacher tells me that there is one consistent principle across the entire ranges, the brands Geo-hydraDynamic Complex. Its the vital operating system of Climate-Smart skincare.It is the only complex in the world that intuitively aligns the upper layers of the skin with the various local atmospheric humidity conditions to achieve optimal hydration in each distinctive climate.Due to the adaptive nature of our complex, it has the unique ability to self-adjust to meet skins ever-changing hydration needs within the millions of nuances of specific climate.

Pour Moi Skincare

Customized for each specific climate, our patented complex is comprised ofingredientswith skin-identical properties including multi-size molecular hydra-actives and a French fungi, high in amino acids and valuable sugars, continues Haslacher. Together, they act as a biomimetic supramolecular network to uniquely boost the hydrating potential of the climate-specific creams and increase the efficiency of the entrapped actives. These include climate-specific antioxidants (for example the Red Snow Algae for Mountain climate and the ocean micro-algaeThermus Thermophilus Fermentfor Marine climate) as well as encapsulatedvitamins including A, C and E and anti-wrinkle peptidesfor an optimal release within the skin and a long lasting effect in each climate.

Haslacher tells me that the reason she has received both global and domestic patents is her three-step system of quenching, drenching, and geo-moisturizing. Step 1 is our Hydrating Balancer. It is an anti-aging liquefier that instantly hydrates, softens and preps skin for the next steps. Step 2 is our quenching serum that intelligently supports skins natural defense system against geo-climatic stressors in specific locations such as the mountains, beaches, plains and deserts. Step 3 is the geo-moisturizing game changer. Select the Day Cream that matches your daily weather to adapt, repair and protect skin in the climate you are in. This allows the customer tocustomize the systemfor their exact location. Think of it as anti-aging skincare for your zip code!

When I asked Haslacher if there is any sunscreen in her products, she tells me, We are working on an innovative sunscreen line which will launch in 2022. However, our formulas do account for how light impacts skin differently in different locations and seasons. While the formulas do not include SPF, they include climate-specific antioxidant strategies.I really like the concept of the brand. I just started using it, so I am excited to see what kind of changes my skin sees.

Reflekt

Reflekt

If you were under the impression that exfoliation means stripping your skin of moisture,Reflektis on a mission to change that with their 3-step hyaluronic acid-based products. Launched in 2017 and founded by Nancy Schnoll, Reflekt is a luxury skincare brand (for any skin type) thats rooted in pharmaceutical and medical principles and centered around simplifying your skincare routine, while delivering clinical results.

Reflekt is a skincare company that believes gentle daily exfoliation is the key to healthy balanced skin. We realize daily exfoliation is a novel concept, but it is the cornerstone of our brand, states Schnoll. The brands hero product,Reflekt 1is an exfoliating cleaner designed for all skin types and is gentle enough to use morning and night. Reflekt 1 was intentionally launched by itself to educate people about the benefits of a skincare regimen that consists of deliberate light exfoliation coupled with the infusion of hydrating actives.

This May, the brand will launch Reflekt 2 Brightening & Hydrating Serum, a silky serum that seals in moisture, brightens and gently exfoliates the skin, and Reflekt 3 Renewing & Hydrating Face Cream that gently exfoliates while moisturizing the skin to promote cell renewal and a firmer and even skin tone.

Reflekt

The entire Reflekt range is vegan, clean, and non-toxic and both exfoliates and hydrates the skin while not disturbing the skin barrier. Each product has unique characteristics. The exfoliating component in Reflekt 1 is the biodegradable jojoba esters that melt from the warmth of the water and your body as you cleanse, explains Schnoll. For Reflekt 2 and 3 the exfoliator is our unique fruit enzyme blend consisting of 9 different fruits (like pomegranate, passion fruit, and pineapple) and varies in percentage depending on the product. The hydrating aspect varies, but whether hyaluronic acid, aquaxyl, or squalene, each product packs a one-two punch of exfoliation and hydration.

I love the Reflekt collection. After using the 3-step system my skin looks dewy, brighter, smoother, and it feels hydrated. I also enjoy the light fragrance.

Saro de Re

Saro de Re

By now, most of us have heard about the benefits of hyaluronic acid for the skin. ButSaro de Retakes the experience to a whole new level. Founded by Mimi Kim, the brand launched last fall with their first product, the freeze-dried hyaluronic acid experience.

Saro de Re is a K-Beauty luxury brand rooted from the medical and pharmaceutical field for the professional results at the comfort of our own home and it is designed for any age, gender, any skin types, and skin conditions, Kim tells me. I have been sourcing ingredients and inventing beauty products for nearly three decades, and I have seen some very impressive technologies, products and unique ingredients that are not available to consumers. My goal over the years has been to make these discoveries available to the masses. When I partnered with a Korean Pharmaceutical R&D team and found something this ground-breaking, I knew we had something very unique.

Not all hyaluronic acids are made equal. Ourhyaluronic acid is 99.9% pure. Nowater, preservatives, fillers, additives, or chemicals. Each tablet is made up of 98.5% highly concentrated hyaluronic acid with a small amount of two additional ingredients for moisturizing: Squalene and Vitamin E.Clean beauty at its core, states Kim when I ask her what makes her formula unique.

Saro de Re

Other hyaluronic acid serums on the market contain primarily water as the number one top ingredient, which means the hyaluronic acid is not in its purest form. Our product has the patent on the method of preparing low molecular weight range that is small enough to permeate, but large enough to attract and retain the most abundant water, continues Kim. In fact, 1000 times its weight in water and the ability to release it for an immediate plumping and hydrating effect on skin with long-lasting results. No other brand has the capability to create HA in this molecular weight, which requires it to be in its purest form.

The ingredients are then freeze-dried and preserved until they are activated by the Saro de Re Pure Activator, which includes adenosine for wrinkle reduction, Niacinamide for skin brightening, and Allantoin and Hyaluronic Acid for hydration.Once activated and applied, it adds instant hydration that lasts up to 72 hours on skin with just one application. No competitive products can make this claim or be used once every other day or every three days, states Kim. Additionally, there are three botanicals included in the activator that synergistically work with the main active ingredients to achieve superior anti-aging benefits including purslane, pomegranate, and White Mulberry. Users can expect instant and accumulativeresultsincluding plumper skin, a brighter, tighter complexion, and improved tone and texture.

I have seen a huge difference in my skin with the addition of this product. I also like the alchemic process of activating the hyaluronic acid. I definitely feel like I am getting a lab-grade product when compared to other hyaluronic acid serums that I have used. It also works great with Reflekt skincare range. As for any follow up products, Kim tells me that the brand will be launching some new products soon.

The Nue Co

The Nue Co

Discussion about the gut microbiome and overall health have become mainstream and correlations between immunity and the gut have been supported clinically. But, the bodys skin is its largest first line of defense when it comes to immunity so it makes sense to treat it similarly. EnterThe Nue Co, a wellness brand launched in 2017 by founder and CEO, Jules Miller that approaches health holistically, as an entire ecosystem.

For too long health issues have been viewed as siloed issues. For example, breakouts are an issue with your skin, so the solution should be focused only on your skin. But actually, your skin is usually the mirror to our gut. Stress plays out on your skin and sleep affects your skin. To get to the root of an issue and drive real results, you have to view health as an ecosystem, states Miller. We definitely take that approach with our skincare - which we view as topical supplements. Whilst many brands focus on what we call, cosmetic ingredients, the kind which deliver on the instant glow and lovely scent but are proven to increase inflammation and erode the skin-barrier over time, every ingredient in our formulas delivers benefits to your skin health-long term.

The Nue Cosskincare formulations are grounded in clinical science and as such provides users with clinical results. They are a blend of natural ingredients, with the best of clinical research, which enables them to drive real, fast results, without compromising the health of your skin or the environment long-term, Miller tells me. There seems to be so much misinformation about skin health, with one of the biggest myths being that elaborate skincare regimes are the secret to healthy skin.Restoring the health of your skin and removing the complication of multiple products from your routine was part of a bigger shift we were noticing towards ending a culture of overconsumption, what some are calling skip-care or skin fasting. The impact of our beauty addiction has been profound, not only on our skin, but on our planet.

The Nue Co

This cycle of pollution, Miller tells me, is also a contributing factor to our skins barrier health. Our skin barrier, or the outermost layer of the skin, is responsible for defending against pollution, UV light, infection, and locking in hydration. The erosion of the skin barrier is identified as the number one cause of skin issues by dermatologists, causing premature ageing, breakouts, hyperpigmentation, sensitivity and dryness, explains Miller. And just like the gut, our skin is home to an ecosystem of microorganisms that help to keep the skin balanced. Our topical microbiome is just as important as our internal microbiome. In fact, its estimated that 21% of our microbiome lives on our skin whereas 26% lives in our gut. Like any ecosystem, it can be disrupted by outside forces and pollutants.

To support the skins barrier health and the skins microbiome, the brand is launching two newskincare products, BARRIER CULTURE Cleanser and BARRIER CULTURE Moisturizer on March 22ndon their website. Using patented, first to market technology, BARRIER CULTURE contains prebiotics, probiotics, and postbiotics to rebuild the skins microbiome. BARRIER CULTURE is the most comprehensive delivery of skin-barrier building ingredients in a two-step routine. In addition to its microbiome technology, BARRIER CULTURE uses anti-pollution ingredients to protect from external aggressors and boost the skins natural immune system; and hydrating actives to replenish and lock in moisture, states Miller.

The cleanser is designedto replace your double-cleanse, by removing dirt, pollution, and makeup without stripping or disrupting the skins PH. Almost immediately, we have found people have noticed a difference to the feel of their skin with a focus on deep-cleaning, rather than stripping. The application of pre, pro and postbiotics works to replenish the topical microbiome, whilst actively calming and conditioning the skin, Miller tells me.

The new moisturizer leaves skin instantly plumped and hydrated. The formula rebuilds and restores your skin barrier, containing ceramides and probiotics that rebuild and restore the skins natural defenses. Niacinamide activates the skins immune system, helping to repair dark marks, scarring and support natural healing and regeneration, whilst squalane protects against pollution and everyday stressors on the skin barrier. BARRIER CULTUREs microbiome technology also delivers an instant soothing effect to the skin, calming irritation and redness.

I just started using the products so I wont see all of the results for at least a month. But, I am already hopeful. I do love the way my skin feels squeaky clean, yet moisturized when I use the cleanser.

U Beauty

U Beauty

U Beauty launched in 2019 byTina Craig(aka. The Bag Snob) with the philosophy of less is more. U Beautyis tech-driven, science-backed, high-performance skincare, Craig tells me. Our strategic and singular products replace excess with essence and provide real results, without the risk of irritation. We're about amplifying your skin with a select, strategic edit of multifunctional products that streamline your routine and simplify your life.

What makes the brands three products, the Resurfacing Compound,The SUPER Hydrator, and the newest productThe SCULPT Arm Compound,is the brands proprietary technology called SIREN Capsule. Unlike most skincare that release actives all over the skin, SIRENS lures damage-causing free radicals to it like a magnet, explains Craig. By attracting only the compromised cells, healthy cells are preserved, while the Capsule releases age-reversing actives on free radicals (generated after exposure to pollution, secondhand smoke and sunshine), which materialize as vulnerable, damaged areas, instead of all over your skins surface. So your skin gets nothing but benefit.

While theResurfacing Compoundcontains the original SIREN Capsules, The Super and The Sculpt feature dual SIRENS. The SUPERs HYDRA-SIREN produces immediate hydration and with five unique types of hyaluronic acid, it continues to hydrate for up to 48 hours. Specifically designed for the arm area, the SCULPT-SIREN contains a targeted blend of marine extracts, probiotics and select ferments. It delivers oxygen and nutrients to the skin, increasing anti-aging ATP levels and boosting hydration, Craig tells me.

U Beauty

U Beautys latest formulation, The SCULPT Arm Compound, is a product of years of dreaming on behalf of Craig. No matter how often I work out, I was never able to change the fragile texture of the skin on my arms. Its not about being thin. Its about a healthy, bouncy skin consistency, says Craig. I can honestly say The SCULPT is unlike anything youve ever used. Thanks to a genius blend of peptides, marine extract, our signatureSIREN Capsule technologyand now the new SCULPT-SIREN, it visibly tightens, tones and sculpts the skin on the arms. Overall, skin is less subject to the effects of gravity and more resilient in its ability to address the visible signs of damage.

I just received The SCULPT so I cant say for certain what the accumulative results will be just yet. But, I can say that my arm skin feels much tighter immediately after applying the formulaso I am very hopeful. When I ask Craig if she will be creating any other body specific products she tells me, Were about taking a 360-degree approach to skincare, which means treating the whole body, not just the face. I will never create a product if theres not a white space in the industry and a personal need for it first. With that in mind, we have some exciting and revolutionary things coming out in the near future, so look out!

Nvidia, Harvard researchers use AI to find active areas in cell DNA – ZDNet

By daniellenierenberg

Researchers from Nvidia and Harvard are publishing research this week on a new way they've applied deep learning to epigenomics -- the study of modifications on the genetic material of a cell.

Using a neural network originally developed for computer vision, the researchers have developed a deep learning toolkit that can help scientists study rare cell types -- and possibly identify mutations that make people more vulnerable to diseases.

The new deep learning toolkit, called AtacWorks, "allows us to study how diseases and genomic variation influence very specific types of cells of the human body," Nvidia researcher Avantika Lal, lead author on the paper, told reporters last week. "And this will enable previously impossible biological discovery, and we hope would also contribute to the discovery of new drug targets."

AtacWorks, featured in Nature Communications, works with ATAC-seq -- a popular method for finding the parts of the human genome that are accessible in cells.

Just about every cell in your body carries a copy of your genome sequence -- a sequence of your DNA about 3 billion bases long. However, only certain parts of the genome sequence are accessible to certain cells. Every cell type -- whether it's liver, blood or skin cells -- can only access the regions of DNA they need for their respective function.

"That allows us to understand what makes every type of cell different from each other, or how every type of cell is affected in disease, or in other biological changes," Lal said.

ATAC-seq finds those accessible parts by producing a signal for every base in the genome. Peaks in the signal denote accessible regions of DNA. This method typically requires tens of thousands of certain kinds of cells to get a clean signal. This makes it challenging to study rare cell types, like the stem cells that produce blood cells and platelets.

However, by applying AtacWorks to ATAC-seq data, the researchers found they could rely on just tens of cells, rather than tens of thousands. In the research described in their new paper, the Nvidia and Harvard scientists applied AtacWorks to a dataset of stem cells that produce red and white blood cells. They used a sample set of just 50 cells to identify distinct regions of DNA associated with cells that develop into white blood cells, as well as separate sequences that correlate with red blood cells.

AtacWorks is a PyTorch-based convolutional neural network that was trained on labeled pairs of matching ATAC-seq datasets -- one high quality and one "noisy." The model learned to predict an accurate, high-quality version of a dataset and identify peaks in the signal.

Running on Nvidia Tensor Core GPUs, the model took under 30 minutes for inference on a whole genome, a process that normally takes 15 hours on a system with 32 CPU cores.

Lal noted that the researchers were able to train the model on any type of cell and then apply it to any different type.

"That's a really wonderful thing because it means that we can train models using whatever data we have available and then apply it to entirely new biological samples," she said.

The model could help deliver insights into a range of diseases, including cardiovascular disease, Alzheimer's disease, diabetes or neurological disorders. It's available on the NGC Software Hub, Nvidia's hub of GPU-optimized software, where any researcher can access it.

"We are hoping that once our paper comes out, other scientists working with different diseases would also pick up this technique and be interested in using it," Lal said. "And we are excited to see what new research and new developments that can enable."

Transform Your Skin Into That Of A Greek Goddess (on A Budget) – GreekCityTimes.com

By daniellenierenberg

Weve all heard of French beauty products and how amazing they are.

But what if I told you that certain Greek beauty products were just as good (if not better) than the high flying ones?

Think La Mere or LaPrairie. These cult favourite beauty brands cost will set you back several hundred dollars.

You dont have to spend a fortune to look good. I always say you can have great skin even if youre on a budget, no matter how old you are.

Greek women have long used natural products from the earth, plants and animals to beautify themselves and look at how immaculate their skin and beauty was.

Heck, one Greek woman launched a thousand ships! (You know her name)

These hand-picked items for skin-care are loaded with Greek olive oil, wine, figsand donkey milk. (Tried and tested by me, GCT Lifestyle Writer Despina Karp)

$40.00

This nourishing cream-to-foam cleanser is good enough to eat and leaves the skin feeling clean, not stripped of everything. Its been formulated with incredible natural Greek Yoghurt and is gentle enough to be used on even the most sensitive of skin types, including psoriasis and acne-prone skin. It is super gentle, yet very effective at thoroughly cleaning the skin and removing daily impurities and makeup. After trying this cleanser, my skin was left feeling as smooth and supple as a babies bottom.

The key ingredients in this beauty are Greek yoghurt which delivers an almost instant dose of pre and probiotics to nourish the skin and kill surface bacteria.

Amaranth seed extract and honeysuckle: These two unique ingredients provide a soothing and calming comfort to the skin.

I always recommend using this twice per day, morning and night for the best results.

Buy here.

$110 (approximately)

Well, there are serums, and then theres this serum! A little pricey, but wait till I explain what this jar of ageless beauty contains.

This is one of the best antioxidant serums Ive tried and for good reason. For starters, its ingredients make it a high-end luxury antioxidant serum, but without the super costly price tag to match.

The heavenly golden fluid is infused with the famous antioxidant saffron, once known as the most expensive spice in the world.

The crimson threads of magic come from dried crocus flowers, grown in the Greek town ofKozani. It takes approximately 70,000 flowers to make one pound of saffron! Did I mention that they bloom only once a year? Plus they need to be picked exactly ONE day after theyve bloomed! Talk about time-sensitive.

The protecting power of the saffron, combined with the copper, peptides, and amino acids combine to make an incredibly effective collagen and elastin boost.

With consistent use, this serum will leave the skin feeling bright and glowing. I often use this serum on my mature-skinned clients before moisturiser and I massage it into the skin until it has been completely absorbed.

I highly recommend paying a little extra and indulging in this serum, it works wonders for mature skin.

Buy here.

$36.99

Here comes the donkeys milk! Dont worry I wont make you drink it but it is a staple ingredient in this product.

It doesnt sound very luxurious or fancy, but Cleopatra allegedly bathed in donkeys milk for softer skin.

In 2013, a study by researchers at the University of Camerino discovered that donkeys milk is very close in structure and composition to human breast milk (Maybe thats why babies skin is so soft!).

EvenPope Francis even drank it as a babyin his native Argentina.

Are you convinced yet?

This cream provides antioxidant, antimicrobial, and anti-inflammatory moisturisation.

The best part of this incredible product are the key ingredients (which according to their website are 97.1% natural ingredients): donkey milk (obviously), aloe vera juice, St. Johns wort, Centella, carob, cotton stem cells, moringa peptides, red seaweed and cross-linked hyaluronic acid (a superacid for the skin).

The donkey milk and Cretan organic olive oil are rich in omega fatty acids, which the skin craves.

It also contains vitamins and trace elements, which deeply nourish and strengthen the skins natural defence against pollution and UVA/UVB light.

The St. Johns wort and Centella extract calm redness and skin irritations.

I highly recommend this daily moisturiser (as donkeys milk is non-comedogenic) for any skin type, except very congested and cystic acne skin types.

Its important to always apply SPF 30+ to protect your skin from the harmful rays of the sun (especially true if you live in Australia).

Buy here at aphroditeusa.com.

So, Ive give you an entire skin routine worthy of Aphrodite herself.

These 3 products can be used one after the other as a bedtime skin routine for mature and dry skin types.

If you are using these products in the morning, be sure to apply an SPF 30+ after all your products to protect your skin.

You dont have to use a large amount of the products too, a little goes a long way with these beauties.

My donkeys milk day cream lasted me 3 months! So it turns out to be a very economical investment.

Its worth investing in your skin as its the largest organ in your body and the amount of chemicals we are exposed to these days can leave our skin in terrible shape if not looked after.

Our skin is also the first thing people look at, healthy and hydrated skin can completely alter your appearance if youve had dehydrated skin for a while.

So, what are you waiting for? Lets get radiant, and prepare to launch a thousand ships! (More like a thousand compliments)

Note: always ask a Dermatologists advice when in doubt, these products arent suitable for all skin types or skin conditions.

Thesauri Greek Caviar: available in Australia for the very first time

How New Yorkers Are Battling the Zoom Effect: 6 Cosmetic Treatments That Are on the Rise – PureWow

By daniellenierenberg

With more folks spending time inside, working from home and literally under wraps (i.e., masks), now is the time for many for some sneaky beauty procedures that would normally require taking time off work, hiding from your social circle and going dark on social media. But now, all your redness, swelling, and post-op symptoms can go undetectedsans burning your vacation days.

In fact, derms and plastic surgeons across the city are seeing skyrocketing increases in invasive and non-invasive cosmetic treatments since the start of the pandemic, thanks to the Zoom boom or Zoom effect.

What the heck is the Zoom effect, you ask? Basically, Zoom and other digital web conferencing platforms have led people to seek out ways to lift and tighten their faces after seeing themselves so often screens. (Note: If your computer camera is positioned lower and pointing up, it actually makes things look worse than they areinvest in a laptop stand, and you wont regret it.)

Laura Altman, a physician assistant at Tribeca Medspa, explains that since her clients are no longer spending money on travel, dinners out or fancy clothing, this disposable income allows them to spend on beauty proceduresnot to mention the added benefit of flexible downtime while WFH. Our clients are spending more per visit and we continue to see about the same number of new clients every month along with current clients who visit us for more treatments, says Altman.

Here are some of the most popular beauty treatments New Yorkers have been taking advantage of while WFH, plus some things to consider in case youre curious about giving them a go yourself.

In fact, requests for jawline filler are up as much as 2,133 percent at BeautyFix Medspa, a clinic with locations in Flatiron and on the Upper East Side. This non-surgical facial contouring enhances the jawline to give the lower face and neck a more defined and slimmer appearance by helping create a V-shape structure, BeautyFix CEO Mark Greenspan tells us. Jawline fillers are usually completed with one 30-minute treatment with no recovery time necessary.

Dr. Alexander Blinksi of NYCs Plump cosmetics and injectables bar has seen about a 25 percent increase in patients with general concerns about facial structure, aging and wrinkles over the last 12 months.

Consultations related to Botox have been requested in all the major treatment areas. The most common areas for Botox treatment remain horizontal forehead lines, 11 lines, and crows feet. We have seen a slightly greater number of patients consulted for TMJ Botox (TMJ is a medical jaw issue from grinding the teeth at night) likely due to increases in stress, and beauty trends of giving the face more angularity and a higher cheekbone, Dr. Blinski tells us.

Intrigued? Side effects from injectables include minor swelling and bruising. (Psst: Read up on our beginners guide to botox here.)

In fact, reports show that more women in the US are using facial skincare products today compared to one year ago, and that lifestyle changes including the effects of COVID-19 have in many ways altered skin care routines in a positive way, says master esthetician and CEO of Repechage, Lydia Sarfati.

At-home peels feature professional-grade ingredients and step-by-step instructions to boost a dull complexion and address specific skin concerns such as aging, discoloration and blemishes without having to go in to see an esthetician or dermatologist. These peels use low percent acids (like this one from PCA SKIN) and require no downtime for healing.

According to new survey data by healthcare marketplace RealSelf, 36 percent of respondents noted theyve seen an increase in the number of pimples since the pandemic started. And those who have had an increase in breakouts noted their chin was the most likely spot, followed by the jawline and cheeks.

Some acne breakouts are a result of wearing masks and the occlusion it causes (dubbed maskne), and other forms of acne are a result of hormonal stress or stress in general. Patients who have had acne scars are using this period to have laser treatments to finally address the treatment of their acne scars, now that they have the downtime, NYC-based cosmetic dermatologist Dr. Michele Green tells us.

One such treatment is eMatrix, a laser that works by stimulating collagen formation and healthy cells. eMatrix reduces the appearance of acne scars, enlarged pores and mild to moderate wrinkles in addition brightening the skin and improving skin texture. Downtime is approximately 48 hours with mild roughness remaining for three to five days. Results continue over three to five months after the final treatment and can be maintained annually (Dr. Green suggests patients receive three to five treatments).

There are multiple ways to treat hair loss, but Dr. Greens preferred method is PRP (Platelet Rich Plasma), a treatment that uses your own blood to promote healing and stimulate the hair follicle to begin a new growth cycle while making hair stronger and thicker. Side effects of PRP may include some tenderness on the scalp after injections and a slight headache or pressure in the treated area. Depending on the severity, Dr. Green recommends four consecutive monthly treatments of PRP injections followed by maintenance treatments every four to six months.

Places like Tribeca Medspa have seen a 50 percent increase in microneedling with stem cells compared to last year. This treatment is designed to reduce the appearance of wrinkles and skin imperfections, with stem cells added to stimulate the regeneration and healing of the skin.

Typically, patients would experience mild redness and swelling for a day followed by possible mild dryness for a few days, at most. Bruising can happen but tends to heal quickly as it is generally fairly superficial, says Tribeca Medspa clinical lead medical aesthetician Holly Montgomery.

Evolution: Lab-Grown ‘Mini Brains’ Suggest One Mutation Might Have Rewired the Human Mind – Singularity Hub

By daniellenierenberg

How we humans became what we are today is a question that scientists have been trying to answer for a long time. How did we evolve such advanced cognitive abilities, giving rise to complex language, poetry, and rocket science? In what way is the modern human brain different from those of our closest evolutionary relatives, such as Neanderthals and Denisovans?

By reintroducing ancient genes from such extinct species into human mini brainsclusters of stem cells grown in a lab that organize themselves into tiny versions of human brainsscientists have started to find new clues.

Most of what we know about human evolution comes from the study of ancient fossils and bones. We know that Neanderthals and Denisovans diverged from humans around 500,000-600,000 years ago, and that the last Neanderthals didnt disappear from Europe until about 40,000 years ago.

Research has also shown that humans and Neanderthals interbred, and that Neanderthals were a lot more sophisticated than previously thought.

From studying the size and shape of fossilized skulls, we also know that brains from archaic humans were roughly the same size as modern human skulls, if not bigger, and appear to be different shapes. However, although such variations might be correlated with different cognitive abilities and functions, the fossils cannot alone explain how the shapes affect function. Luckily, recent technological advances have provided a new path to understanding how we differ from our extinct relatives.

Sequencing of ancient DNA has allowed scientists to compare genes of Neanderthals and Denisovans with those of modern humans. This has helped identify differences and similarities, revealing that we share most of our DNA with Neanderthals and Denisovans.

Still, in specific regions, there are gene variants exclusively carried by modern humans. These human-specific DNA regions may be responsible for traits that separate our species from our extinct relatives. By understanding how these genes work, we can therefore learn about the traits that are unique to modern humans.

Studies comparing archaic and modern DNA sequences have pinpointed differences in genes important for the function, behavior, and development of the brainin particular genes involved in cell division and synapses (which transmit electric nerve impulses between cells). These have suggested the human brain matures more slowly than the Neanderthal one did.

Specifically, the development of the orbitofrontal cortex in infants, which is thought to be involved in higher-order cognition like decision-making, might have changed significantly but subtly since the split from Neanderthals. Humans also reach sexual maturity later than their ancestors did, which can help explain why we live longer.

It has long been unclear which evolutionary changes have been the most important. A team of scientists led by Alysson Muotri at the University of California, San Diego, recently published a study in Science that shed some light on this question.

They did this by growing mini brainswhich are known scientifically as organoidsfrom stem cells derived from skin. Brain organoids arent conscious in the way we arethey are very simple and do not reach sizes larger than around five or six millimeters, due to a lack of blood supply. But they can emit brainwaves and grow relatively complex neural networks that respond to light.

The team inserted an extinct version of a gene involved in brain development in the organoids using the Nobel-prize winning CRISPR-Cas9 technology, often described as genetic scissors, which allows precise editing and manipulation of genes.

We know that the old version of the gene was present in Neanderthals and Denisovans, whereas a mutation later changed the gene into the current version that modern humans carry.

The engineered organoids displayed several differences. They expanded more slowly than the human organoids and had altered formation of connections between neurons. They were also smaller and had rough, complex surfaces compared to the smooth and spherical modern human organoids.

The study identified 61 genes that are different between modern and archaic humans. One of these genes is NOVA1, which has an essential role in regulating other genes activity during early brain development. It also plays a role in the formation of synapses.

Altered activity of NOVA1 has previously been found to cause neurological disorders such as microcephaly (leading to a small head), seizures, severe developmental delay, and a genetic disorder called familial dysautonomia, suggesting it is important for normal human brain function. The version that modern humans carry has a change in one single letter of the code. This change causes the genes product, the NOVA1 protein, to have a different composition and possibly a different activity.

When analyzing the organoids, scientists found that the archaic NOVA1 gene changed the activity of 277 other genesmany of them are involved in creating synapses and connections between brain cells. As a result, the mini brains had a different network of cells to those of a modern human.

That means that the mutation in NOVA1 caused essential changes in our brains. A change in a single letter of the DNA code possibly sparking a new level of brain function in modern humans. What we dont know is how exactly this happened.

The team has said they will follow up their fascinating finding by investigating the other 60 genes in more detail, to see what happens when you alter each one or a combination of several.

Its no doubt an intriguing area of research, with the organoids giving important insight into these ancient species brains. But we are only at the beginning. Manipulation of a single gene will not capture the true Neanderthal and Denisovan genetics. But it could still help scientists understand how some human-specific genes work.

New Controversy for Stem Cell Therapy That Repairs Spinal Cords – The Great Courses Daily News

By daniellenierenberg

By Jonny Lupsha, Current Events WriterAn alternative to using human embryonic stem cells is to use pluripotent stem cells, which refers to the ability of a stem cell, such as skin cells from an adult, to give rise to other differentiated cell types. Photo By Yurchanka Siarhei / Shutterstock

Patients who have received treatment from their own stem cells to repair their spinal cords are at the center of controversy after the stem cell therapy was fast-tracked in Japan in 2018. Despite 13 patients showing considerable recovery in response to the treatment, the means to this end have suggested improper shortcuts taken in the last several years.

It isnt the first time that stem cell research has been in the spotlight for ethical reasons. One controversial method of obtaining stem cells is to take them from human embryos, which has been argued about for decades. However, alternatives to embryo use are coming to pass.

In his video series Biochemistry and Molecular Biology: How Life Works, Dr. Kevin Ahern, Professor of Biochemistry and Biophysics at Oregon State University, said much about stem cells and the science that surrounds them.

There are two things that are special about stem cells, Dr. Ahern said. One is that they are capable of dividing indefinitelythat is, as long as the organism is alive. The other is that they are undifferentiatedtheyre like a child who hasnt yet chosen whether to be an astronaut, ballerina, surgeon, or an artist.

Dr. Ahern said that when stem cells divide, they can either differentiate and become a specialized cell or they can go back into the stock of stem cells. In an embryo, at the earliest stages of development, the fertilized egg divides to produce a certain number of unspecialized cells called embryonic stem cells. They become specialized by receiving certain signals, so scientists can learn what these signals are and send them to unspecialized cells to make them develop as they wish. This could mean making them become cells to repair nerve damage, heart muscles, and more.

However, some see this as tampering with nature and/or stealing cells from the embryo. Regardless of our opinions one way or the other, these ethical concerns have been raised, prompting scientists to find alternatives.

How else can stem cells be obtained, if not from embryos?

One solution is the production of what are called induced pluripotent stem cells, or iPS cells, Dr. Ahern said. Pluripotent refers to the ability of a stem cell to give rise to other differentiated cell types. To do this and yet avoid working with cells from a human embryo, scientists begin with differentiated somatic cells [like] cells from the skin of an adult, for example.

Once theyve isolated the differentiated somatic cells, scientists reverse engineer them into a state in which they can become any number of differentiated cells or tissues. Dr. Ahern said that iPS cells have been used to create beating heart cells, motor neurons, light-sensing photoreceptor cells, insulin-producing pancreatic cells, and more.

In 2017, Japanese researchers reported that monkeys with Parkinsons showed great improvement after treatment with dopamine-producing neurons derived from iPS cells, Dr. Ahern said. In 2018, clinical trials with humans were begun using iPS cells to treat Parkinsons, heart disease, and macular degeneration.

For now, stem cell therapy remains no stranger to controversyor results. The debate raging around them will likely continue in one way or another for some time.
