The Science of Skin Aging with OneSkin Co-Founder Alessandra Zonari, PhD
Show Snapshot:
Let's be honest—walking down the skincare aisle in midlife is overwhelming. So many products, so much BS. If you're tired of "anti-aging" products that promise miracles, this show will help you cut through marketing hype, make you a shrewder shopper, and give your skincare smarts a science-backed glow up.
Get a crash course in the science of skin aging with Dr. Alessandra Zonari, who holds a PhD in skin regeneration and tissue engineering and is the co-founder of cult-favorite OneSkin, a line of skin, suncare and scalp products. Alessandra and her team spent five years screening 900+ peptides to discover the first molecule that targets "zombie cells"—damaged cells that accelerate skin aging after 30.
We cover what makes skin age, why some people’s skin ages faster than others, why lifestyle beats genetics in aging—and which choices matter most. Plus, a primer on spotting science-backed products versus lotions and potions hyped only by clever marketing. Understanding the real science behind skin aging isn't about skin-deep vanity—it's about making informed choices that protect your health and confidence as you age. Learn to love (and protect) the skin you're in, beauties!

Welcome to A Certain Age, a show for women who are unafraid to age out loud. I'm your host, Katie Fogarty.
Beauty's summer is in full swing, and where I live on the east coast, the weather has finally caught up with the calendar. It is hot and sunny. We recently celebrated National Sunblock Day. Wait, what? You don't celebrate National Sunblock Day? Well, you should, because sun care, skin care is something we need to honor, acknowledge, get on and stay on top of. Taking care of our skin, protecting it from sun damage and lifestyle and environmental stressors, needs to be a 365-day-a-year situation.
But lucky us, we have a phenomenal guest today who can walk us through what we need to know to boost our skin span - the length of time where our skin is healthy and functional and looks and feels our best. Today, I'm joined by scientist and PhD Dr. Alessandra Zonari, a co-founder of what is about to be your new favorite skincare company, OneSkin.
Alessandra has degrees in biology and stem cell biology and a doctorate in skin regeneration and tissue engineering. As co-founder and Chief Scientific Officer of OneSkin, Alessandra has taken her expertise to develop the first peptide scientifically proven to switch off the senescent cells in the skin - one of the main drivers of skin aging.
If you recognize that healthy skin is a lifelong journey, if you want help decoding and understanding the science behind skincare superheroes like peptides and hyaluronic acids, if you've ever looked at a bottle of cream marketed as anti-aging and thought to yourself, "Does that stuff really work?" - stick around. We are getting into all things science and skincare today.
Welcome, Alessandra.
Dr. Alessandra Zonari 2:03
Thank you, Katie. I'm very excited for this conversation today.
Katie Fogarty 2:08
Well, I am as well, because you very kindly sent me some of your amazing products before we hopped on this recording session. And it is such a treat to interview the founders of companies that are putting amazing products on store shelves, that are giving us different options as we age.
And I did my research, because I've been slathering my skin with your products, and I hopped on your website, and I saw some surprising language that I want to ask you about. The website states that OneSkin did not set out to be a skincare company. Can you share the story behind the founding of OneSkin and what made you bring it to life?
Dr. Alessandra Zonari 2:42
Yeah, so I'm very proud to be co-founder of OneSkin with three other brilliant female scientists as well. We met in Brazil a long time ago, when we were doing our masters and PhDs, and we bonded together over this interesting dream of, like, this passion in science and somehow, like translating the science - making the science that we were researching available to help people's lives.
But when we started OneSkin, and this is back in 2016, our first goal was to use our science to build skin models in the lab and validate efficacy of products that are in the market and understand how they are performing in terms of reversing the biological age of the skin. And we soon started to realize that none of those products were addressing the root causes of skin aging. They were more like working as a makeup solution, but not really treating the health benefits on the skin. And we saw then an opportunity to shift our first idea into trying to unravel new solutions that would benefit skin health.
So it was a long process of five years of research until we found our peptide.
Katie Fogarty 3:56
That does sound like a long process, but you said that your peptide addresses the root of skin aging. What is the root cause of aging in our skin?
Dr. Alessandra Zonari 4:06
So not only on our skin, in our whole body, when we are getting older, what's happening at the cellular level is that we are accumulating damage. And when a cell accumulates a lot of damage, this cell stops dividing, and usually it's supposed to die and be replaced by a new cell. But with aging, some of those damaged cells, they accumulate, they stop dividing, they don't die, and they secrete inflammation. And this inflammation that is secreted by those cells starts to deteriorate the surrounding tissue, unbalancing the environment and making, on the skin, making more collagen breakdown, thinning the skin barrier.
So one of the causes of why our skin starts to lose elasticity, firmness and becomes weaker is because we are accumulating those damaged cells that are also known as senescent cells, or more popularly, zombie cells. Zombie cells because they were supposed to die, and they don't die, and they secrete this inflammation.
Katie Fogarty 5:41
Well, first of all, zombie cells is a lot easier to say than senescent, because I was trying - like, I literally spelled it out phonetically in the question I was going to ask you, and I still could barely say it. And I think zombie cells, you know, really conjures up really vividly what's happening. Some of these cells are hanging around, causing disruptions, you know, showing their ugly, unwanted faces.
So you've developed a peptide, OS-1. How does that work to combat zombie cells, the senescent cells, and how does it work to support skin longevity?
Dr. Alessandra Zonari 6:15
When we started understanding that those zombie cells play a critical role in the skin aging process, and that the products in the market, they're not addressing or targeting those zombie cells, we started looking, screening for a new molecule - a new peptide - that would reduce the accumulation of the zombie cells in the skin.
So after screening over 900 peptides in a process that took us two years to screen, optimize and validate this novel molecule, we identified what we call the OS-1 peptide. That's a peptide that's able to reduce the inflammation that's secreted by those zombie cells and avoid the accumulation of more zombie cells in the tissue.
So by doing this and reducing the inflammation, it allows the healthy cells to function in a better state. So it allows the healthy cells to restart producing more collagen, a stronger skin barrier. And what we perceive, what we can see, is this improvement in the overall appearance of the skin. And when we measure in our lab the biological age of the skin, we see that it's actually being reversed. So the skin, after treating with this peptide, is not only looking better, but at the cellular level, it's functioning as a younger skin.
Katie Fogarty 7:45
Well, it's amazing. So you screened 900 peptides, which is an enormous number, to come up with the peptide that works and reverses this skin cellular breakdown that you have identified. When you're talking about a peptide, it's been a very long time since I've taken a science class. And I know that your company is founded by four female scientists that you have between you - you've got PhDs in stem cell biology, immunology, skin regeneration, bioinformatics, which I have never even heard and had to look up.
So this is why I'm so grateful that you're here, because you have a wealth of information that the average listener and average woman doesn't have when they're looking at considering skin treatments. So with this one peptide that you found, out of 900, are peptides something that occur naturally, or do you create them in a lab?
Dr. Alessandra Zonari 8:40
So peptides, they are like small pieces of proteins. They are made by amino acids - that's the same building blocks of a protein. And when you have those small pieces of protein in our body, they work as a signaling molecule. They can give signals to your body to do something that you want. For instance, they can signal the zombie cells to produce less inflammation.
And the peptides, they can be found naturally, even in our body or in nature. This one, the OS-1 peptide, it was really designed. It came from research really specifically designing for this target. So it's a completely novel molecule that you don't find anywhere.
Katie Fogarty 9:30
And so how did you identify it? Is this now patented? Is this a peptide that OneSkin only owns?
Dr. Alessandra Zonari 9:38
Yeah, after we identified this novel molecule with our patent, it's a proprietary molecule that you will only find in OneSkin products.
Katie Fogarty 9:47
And so that must have been an exciting moment. After five years of research, spending time with 900 peptides, what came next when you identified this peptide that is really the hero product that exists in all of the skincare and hair care and eye care options that you offer? How did you then turn it into products that I'm currently using in my own bathroom?
Dr. Alessandra Zonari 10:12
So when we identified this molecule, and we started testing in our lab against other skincare molecules, and we were seeing that it was outperforming, was doing something that other molecules are not doing, we were still a group - a small group. We were seven, at that moment, of scientists in the lab doing research, and we always dreamed about translating this research, right.
But the first thought that we had was like, "Okay, let's license this novel molecule to a big company, because we don't know how to bring this to the market." But the process of talking to big companies, the investment needed was taking so long, and we had this urge, like this dream of translating the science, that we then sat in a meeting room, we decided, "Okay, let's formulate this into a first product. Let's run clinical studies. Let's validate that the findings that we are seeing in the lab, when people apply this into a formula that's topically applied, they will see the benefits. And let's bring this to the market."
And that day was really like, "Oh my gosh." The kid Alessandra, the small girl that dreamed about science and curing diseases, was so excited about it. And people said, "You girls are crazy. You're scientists. You don't know anything about skincare, beauty market. It's completely overwhelmed. You will not break through the noise." But we knew that we had something special, different, unique, and we would rely on our science to bring this to the market.
So in 2021 we launched our first product. It was OneFace. It was a dream coming true in terms of the first scientists that really saw the research into a product. But we went, we started this journey of creating the brand, learning on the go, because we had zero experience with marketing and what we would do next. We knew we wanted to launch a product, and then once we launched, we realized that there was a line of products that we could create to complement a skincare routine.
So we have been spending the past three years - every year we launch a new product that was all very well studied on how we would formulate and create this product in the lab. We run clinical studies, and then we bring to the market. And now, four years later, we have been seeing the results of our molecule improving the skin quality in a lot of people, which is very, very gratifying for us.
Katie Fogarty 12:59
And you know, it's really resonating with customers, because you have a massive Instagram following, for example. I mean, I see people sharing your products all the time. And when we got connected and your communications person said, "I'd love to have Alessandra on the show and to talk about OneSkin," I was like, "I have been so curious about OneSkin. Let's absolutely do this."
We are going to talk a little bit more specifically after the break about what the products look like, how people can be using them. I also want to ask you about why some people seem to age more slowly than others, whether it's genetics or lifestyle or skincare. I know that your focus is also on longevity science, not just skin science. So we're gonna explore all that in a minute.
Before we head into this break though, I want to let listeners know that Alessandra was not only generous enough to send me four of her products - I've been using the face and the body, the eye lotion, which I love around my delicate skin, and of course, I'm using the SPF because I am Irish, and you know, I need to be careful. So I want to let everyone know that she's offered a discount code if you want to try these products as well. It's 15% off your first order with code ACA. You can head to oneskin.co - that's O-N-E-skin.co, not .com - for 15% off with code ACA.
We're heading into a break. We'll be back in just a minute.
[BREAK]
Katie Fogarty 14:31
Alessandra, we're back from the break. When we went into it, I was asking you about why some people seem to age more slowly than others. Skin across different groups of people, whether maybe it's based on melanin or lifestyle or culture or exposure to toxins, seems to age more slowly for some people than others. I would love to hear your take on whether or not that is true, and what are the factors that come into play?
Dr. Alessandra Zonari 14:53
Yeah, so one thing for me that was fascinating when I started to research aging is that first I had the idea that genetics would be the most determinant on how I age and how I'll get older. But science has shown that genetics only plays 10 to 30% of the role of how you will age. The majority of how we are aging is due to our lifestyle choices that we take over the course of life.
And you can see this in some studies with twins that have exactly the same genetics, and there's one study very famous, that one twin smoked their whole life versus the other one that never smoked, and you can see that they have the same age, same genetics, but they look completely - one looks 20 years younger than the other one.
So lifestyle is really, really one of the most determinant players on how we are aging and how our skin is aging. This is good because it gives us the control of how we will age, because now I can decide on my sun exposure, on my diet, on how I manage my sleep, stress, and this will help or worsen the way I'm aging.
So in conclusion, to your question, lifestyle is more determinant on the way that we are aging versus genetics.
Katie Fogarty 16:29
Let's talk a little bit about sun now, because we're in the months of summer fun when we're recording the show. People want to be outside. You are from Brazil, a part of the world that is famous for its beach culture and its sort of outdoor living and great weather. Talk to us about the role of - I think we all know we need to use SPF. But do you avoid the sun altogether? Is it something that you embrace in doses? Talk to us about what you recommend for our sort of daily living.
Dr. Alessandra Zonari 17:01
UV radiation coming from the sun is one of the main drivers and accelerators of skin aging, because excess exposure to UV can damage your skin and produce more of the zombie cells. So it accelerates the aging process, and it's very important for you to understand your skin type and where you are geographically, how much is the UV index where you live, and understand that the sun can have some benefits to your health, but anything that is exposing your skin to burn is not bringing benefits at all, and is only causing damage and accelerating aging.
So when you understand this ratio, you can make the wise choice of: if my skin is super fair, if I'm in a place that has high UV index, it's summertime, I'll be outdoors, I'll be exposed to the sun, I need to protect my skin. I need to use a broad spectrum SPF and avoid the excess of sun that can burn my skin.
So in general, the SPF should be used daily to protect from excess exposure. But there is also this key notion of your skin type, how much you're exposing to the sun. I usually, for instance, in my case, I run outdoors early morning, during sunrise, around like 6:30, 7:30 AM and I don't apply a lot of sunscreen at that time because the sun at that time is just giving me benefits. But during the weekend, if I'm going out 10 AM to be outdoors, I make sure I'm protecting my skin and reapplying the sunscreen to avoid the damage that comes from the sun.
Katie Fogarty 19:07
So smart choices based on time of day, where you live, what your personal skin color is. Question about some myth busting: if people have darker skin and they're more melanated, do they need less sunblock?
Dr. Alessandra Zonari 19:20
So the melanin definitely helps protect from UV radiation. So a skin that has more melanin can protect more from the UV damage compared to a skin that has less melanin. But it's not all protection. So even a darker skin tone can get burned from the sun, and when it gets burned - like too much exposure - it can create damage on your skin.
Katie Fogarty 19:52
If OS-1 is a peptide that helps reverse the zombie skin cells that are appearing, does it help correct sun damage that we've incurred?
Dr. Alessandra Zonari 20:03
Yeah, so the OS-1 peptide, it's avoiding new damage. It works super well in this prevention, but it's also reversing some of the damage that was already accumulating. When you are clearing out those zombie cells, you're reversing the damage.
Depending on how much damage you have accumulated, it's harder than preventing novel damage and more acceleration of the aging process. So the peptide has the capacity to do both, but the reversing side, it takes more time, and it's not as dramatic as the prevention side. So it's not that a skin that is 60-plus with a lot of age spots will be looking again as an 18-year-old skin, but some of that damage will be reversed, and it will stop accelerating this aging process. So you will feel your skin more healthy, and some of that damage you can visually see - reducing the age spots and reducing the fine lines and improving the firmness and the density of the skin.
Katie Fogarty 21:16
Is there a specific age when our skin's aging process accelerates? When we should start using these products? Is it gradual? Is there a particular age where we can start to best benefit from the OneSkin products?
Dr. Alessandra Zonari 21:30
Yeah, so we did a lot of research where we analyzed the DNA of skin samples from young ages all the way to 80-plus, and what we learned is that there is a shift in the behavior of the cells when we turn 30. So things start to become more unstable after 30 years old. And between 45 to 60 in women, because of perimenopause and menopause and the drop of hormones, you see more of an acceleration of the aging process. So it comes gradual, but it does accelerate with menopause in women.
Katie Fogarty 22:18
And so for people who are after the age of 60, is there still the ability to derive some of the benefits of your signature peptide, the OS-1? At what point does the product not work as effectively?
Dr. Alessandra Zonari 22:34
So for ages above 60, definitely the skin has accumulated, depending on how you treated your skin your whole life, it has accumulated more damage than a skin of 30 years old. And the peptide can work because also there's more damage accumulated, the peptide can work reversing this damage, and you see a benefit that sometimes even can be a little bit more impressive than when you are using it at a young age.
And we did a clinical study specifically on this demographic, 60-plus, with our OS-1 Body - the body lotion. And it was incredible to see that the body lotion was able to improve the quality of the skin and the firmness and the elasticity of the skin in the arms, in the legs, to the point that it can reduce some of those tearing and bruises that can come later on when your skin is too fragile.
Katie Fogarty 23:32
So talk to us a little bit about the clinical validation process in this space, you know, for your products in particular, and maybe what else is going on, because when we walk into a drugstore and we get online, we are confronted with a lot of products and a lot of choices. I'm really excited to explore yours right now, but help us become an educated, smarter consumer when we're making our buying decisions.
Dr. Alessandra Zonari 23:56
So a product in the skincare industry to get to the market, it's not mandatory to run any clinical validation study to launch a skincare product. So that's why there are so many products in the market launched all the time. And you can get confused because the marketing claims, they are very similar between different products.
But when you go to a website to learn more about a brand, you can look on the product page if that product has any type of clinical validation, and usually you have two types of validation: a consumer perception that mainly will tell you data like "90% of the users reported that the skin feels more hydrated. 95% of the users reported that the skin feels more firm." So these kinds of studies, they are useful because they are validating that people can feel the results of a product, but they are just the consumer perception.
The next level is when you add instrumental analysis or blinded analysis by an expert. So at OneSkin, we always run both, and we go all the way. First in the lab, we run a lot of tests using our skin models in the lab to combine the ingredients to make sure the formula that we are generating, it's not causing any side effect to the skin, is delivering the benefits of our peptide. Then we go to consumer perception and to third-party clinical study with instrumental measurements that will analyze: okay, after 12 weeks, not only 95% of the participants feel the skin is more hydrated, but when measured with an instrument, we can see 35% improvement on hydration or on the skin barrier function, on firmness and elasticity.
So when you have instrument results, they are quantified and they are not biased. They are not just perception. They are really real measurements. Our clinical studies, they are published in scientific journals, meaning that scientists and experts in the industry, they read our clinical study, they read and they vetted that what we are showing there, it's something legit.
So getting all the way to this - all levels of consumer perception, clinical study and scientific publication. This is the top that you can see on a skincare product or brand. And then you can use those rules to try to identify if a company, how serious they take the product development and the claims that they are doing on their website.
Katie Fogarty 26:59
And it sounds like OneSkin takes it pretty seriously, since you've gone to the highest level with all your products. I'm going to ask you a question that you might not have an answer to. You said that many products go out there and anyone can market these, you can develop your skincare products. Do you have a sense of how many other companies do the highest level? If I'm looking at 100 ingredients on a shelf, what is your best guesstimate about how many have gone as far as OneSkin has?
Dr. Alessandra Zonari 27:26
I would say 1% or less. It's really the minority of the brands that go all the way to the level of commitment on studies that we do.
Katie Fogarty 27:40
So no wonder this took five years.
Dr. Alessandra Zonari 27:45
And I understand why a lot of companies do not do it, because it takes a lot of time and investment. So sometimes, yeah, it's easier to try to build a product and already start selling without all of that.
The difference for us at OneSkin that we see is that all the investment that we did to find something unique is now being paid off in products that people really enjoy to use, that they subscribe to use, that they continue using for a longer time, while other brands, they have a lot of people try your product and they never come back to buy a second time. We have a very loyal customer base that people see the benefit, they believe in the science, and they continue using because this product - the benefits come with the long-term use.
Katie Fogarty 28:39
They're visible. Exactly. By 12 weeks, they'll have the proof in their skin. I have been using your products only for a few weeks, so I'm so excited to get to 12 weeks when I can have a better sense.
What you just said about your subscription rate really is a great segue into my next question, because I've been using your products and I opened up the box - the packaging box that each came in - on the lid of each one of your boxes, there is an intriguing label, and it says, "I am refillable" with a little exclamation mark. And within the box, it'll say, "Please keep the outer bottle. Please keep the outer shell of this product for your next order." So walk us through what happens when we refill our order. Is there an insert that we can then use? Is this a conscious choice for sustainability? Why these refillable options?
Dr. Alessandra Zonari 29:29
Yeah, because we build these products to be in the customer journey for the long term, and they don't need to be searching and trying new products. Being refillable was something that made sense from the beginning. So we can reduce the amount of plastic we are generating. We are committed not only to improve your skin longevity, but also a little bit of our contribution to the planet longevity as well.
So when you become a subscriber, your first order, you receive the full package. And then on your next orders, you receive just the pouch that goes inside the main package, and then you don't receive the outer plastic anymore. And this has already helped us - the last data that we collected, that was in April this year, we had avoided already 37,000 pounds of plastic that was not generated just because we are refillable.
Katie Fogarty 30:34
That's an incredible number when you think about savings for you and for the environment and for all of us not to be having more plastic in our lives. I've had a number of other beauty founders on the show, and I have learned how much waste there is in the industry, and how thoughtful, conscious founders like yourself are looking to both serve their customers, but also keep an eye on the planet for us. So it's terrific to hear that that's built into your packaging, into your distribution model as well.
I want to segue now and ask you a little bit about founding a company in a different country. I love the fact that all your founders are from Brazil. Did you all know each other before? What made you come to the US and do this? I'm just curious about the process of like, did you know each other? Did you find each other after you started working on this? Fill us in a little bit on the genesis of the company.
Dr. Alessandra Zonari 31:29
Yeah. So we met each other between the years of 2004 and 2009. The four of us were connecting individually, and by 2009 we all knew each other. We were doing our masters in the same university in Brazil. Three of us were in the same lab, and Mariana, that's the bioinformatician, she was in the next door lab. So we all met when we were on this phase of our lives, learning to be a scientist. From the masters we went to the PhD program, and we were all doing this research around stem cells, tissue engineering and bioinformatics. And in common, we all had this passion and that dream of one day getting out of academia and building something that can improve people's lives.
So when we finished our PhDs, I was still doing research in academia. I moved to Portugal, and I was doing postdoc in Portugal, and the three girls in Brazil, they started a company in Brazil that was one of the ideas prior to OneSkin - to develop different models, not only for skin, to test drug molecules in the market. In Brazil, back in 2014, the ecosystem there is not the best for biotech. It's not so developed. You don't have a lot of mentorships. You don't have investors. So it was a very slow process for the girls to try to build a biotech company in Brazil.
But then they learned about an accelerator program in San Francisco that helps scientists to become entrepreneurs. So in 2016, Carolina moved to San Francisco, and when she joined this acceleration program, they said, "Okay, you need to decide which area you want to focus on this drug testing platform." And they decided to focus on skin. And that was my expertise from my PhD and postdocs. So Carolina invited me to come to San Francisco and join the team. And we started OneSkin here in the Bay Area.
And after going through this program at IndieBio and being in a place surrounded by a lot of other biotechs, good universities, the ecosystem is so much more encouraging and giving you the opportunities that it didn't make sense to go back to Brazil, and we knew that we had a chance to make our dream come true. We were in the right place, and we needed to give our best.
Katie Fogarty 34:20
You've used the word "dream" several times. It just makes me happy to hear it, that you can hear it in your voice, the excitement for having taken this idea from academia and research and studies to a physical product and bringing it to life and connecting it to consumers and having enthusiasm from all of your many Instagram followers. What was it like when you first saw that first bottle, that first package, that first product out in the wild on a store shelf, even if it was a virtual shelf?
Dr. Alessandra Zonari 34:53
I talk about dreams because I'm a big dreamer. I'm always with the whole team and everyone - we dream first and then we build and we make our dreams come true.
And for us, the first time we got that, we received the package and we put the product - that was the sensation. We were after five years - we moved out of our countries, we were far from all our family. We arrived here without knowing anyone in the United States, in San Francisco, and just seeing that product ready was exciting and at the same time scary, like, "Will people buy? How will we sell this product?" So it was a mix of a lot of excitement and a lot of unknown of what will be the next steps, but at the end, it was a combination of a dream coming true. And I, as a scientist, I always say each step of this journey, it's a different moment of our lives and the journey itself. But at that time, I felt that my early dream of why I became a scientist was really turning to be accomplished.
Katie Fogarty 36:08
It's such an exciting story. I love hearing it. I love the fact that you're four female founders who are scientists, who've created a product, had a vision, brought it to life. You have created marvelous, lightweight products that smell good, they feel good on your skin. I cannot wait for 12 weeks to see all of the impact it's going to have on me.
And I also really appreciate the language that you use to describe your products, your goal, your mission. It's about increasing your skin span, increasing longevity and the life and overall health of your skin. Getting to midlife, where I am, we shift from wanting to look a certain way, but to have functional fitness, right. We want to feel strong and powerful and want to age well. And I think that I see and hear from the women in my life and the women who come on this show that we are interested in looking and feeling our best and feeling beautiful, but we are looking at taking care of our health.
And these anti-aging products do not speak to us or treat us respectfully, and the fact that your products really are about lifespan, skin span and aren't meant to make you forever young. They're just meant to make your skin as healthy as it can be for as long as it can be - that just feels so resonant.
So thank you so much for being with me today, Alessandra. I enjoyed learning more about your company, your background and how you've brought your dream to life. Before we say goodbye, though, how can our listeners find you and OneSkin?
Dr. Alessandra Zonari 37:41
Yeah, the best way to find us is visiting our website oneskin.co. We have a lot of content on our blog that explains our science, all our products, breaks down our clinical studies. You can also find the scientific publications on our website that are a little bit more technical, but they are there if anyone wants to take a look. Follow us on Instagram. OneSkin.co is also our handle, and if you have any doubts, any questions, just email our support or customer care. We love interacting, learning from our customers.
