We're thrilled to share a major milestone in our mission to provide specialized treatments to target and reduce the visible and invisible signs of aging. OneSkin’s clinical study on OS-01 EYE has been published in the International Journal of Cosmetic Science!
Backed by extensive lab and beta testing before launch, OS-01 EYEs clinically validated results are now peer-reviewed and proven to increase elasticity, firmness, and hydration around the eyes. Join us as we share the methods behind the clinical study–and how these results confirm the extensive evidence gathered in the OneSkin lab.
01
What Makes OS-01 EYE Unique?
The skin around your eyes has been shown to age faster and contain higher levels of senescent cells. (1) The secretion of inflammatory signals by senescent cells contributes to collagen degradation, resulting in a loss of skin firmness and resilience, which manifests as wrinkling and sagging. (2, 3) That's why the OS-01 peptide, which blocks inflammatory signals by senescent cells, is the perfect ingredient to tackle advanced senescence around the eyes. (4)
Combined with actives known to boost collagen production and increase moisturization, such as acetyl hexapeptide-8, Fucus vesiculosus extract, Moringa oleifera seed extract, and hyaluronic acid, OS-01 EYE delivers a synergistic formula strategically designed to mitigate the exacerbated effects of aging in the delicate eye area skin.
02
How the Study Was Conducted?
Following our rigorous lab testing, we partnered with a third-party research organization to test our formula on participants for 12 weeks and then measure its impact on factors like hydration, firmness, and transepidermal water loss at three intervals. Each person applied a dime-sized amount of OS-01 EYE twice daily, alongside a cleanser (PREP), moisturizer (OS-01 FACE), and sunscreen (Neutrogena Oil-free moisture SPF 35) to reduce variability in our results.
Instrumental Evaluation
Getting objective, reliable data is one of the most challenging aspects of testing any skin care product. To take the guesswork out of this process, we settled on four tools to objectively measure skin hydration, skin barrier function, firmness, elasticity, and visual analysis:
- Corneometer: Corneometers use changes in skin capacitance and conductance to measure changes in skin hydration. To ensure reliable results, measurements were conducted in triplicate at each assessment. (5)
- Evaporimeter: Trans-epidermal water loss is a key indicator of skin barrier function; a weakened skin barrier will lose more water to the environment. By assessing the vapor pressure gradient between the skin and surrounding air, evaporimeters help our researchers ascertain improvements in skin barrier function, with lower TEWL indicating enhanced hydration retention. These measurements were taken twice for accuracy. (5)
- Cutometer: Skin is a complex system containing contrasting elastic and viscous fibers, elastin, and collagen. The cutometer uses gentle suction to mechanically deform the skin and provide insights into the biomechanical properties of each subject's periorbital skin. (5)
- Clinical Photography: Clinical before and after photographs of each subject's face were taken using a VISIA-CR scanner. These photographs' accuracy, high quality, and standardized nature allow for a more comprehensive visual analysis of skin condition changes from various angles. (5)
Blinded Expert Clinical-Grade Evaluation
To preserve the study's integrity, an expert grader, blind to previous scores, evaluated each participant’s test site imagery using a standardized scoring system. This approach guaranteed that the evaluations were unbiased and relied solely on observable changes.
Self Perception Surveys
Finally, we gathered valuable insights through self-assessment questionnaires completed by participants at baseline, week 4, and week 12. They reflected on how the product impacted various skin parameters, including overall appearance, radiance, firmness, hydration, roughness, dark spot reduction, and puffiness. Participants rated their satisfaction on a 5-point scale, complementing objective measurement data and providing a comprehensive understanding of the product's performance.

What Were the Results of OS-01 EYE’s Clinical Study?
Our third-party research partners observed the following noticeable improvements in skin health.
- Improved hydration: 87.5% of users showed an impressive 32.5% average improvement in skin hydration.
- Enhanced skin barrier function: By strengthening the skin barrier, 70% of users showed, on average, a 17% improvement in preventing trans-epidermal water loss.
- Better elasticity: 86% of users showed a marked improvement in under-eye skin elasticity with an average improvement of +23.58%
- Firmer skin: 73% of users showed a significant improvement in skin firmness with an average improvement of +10.19%.
- Improved skin appearance: After just 4 weeks, 90.91% of users reported that the overall appearance of their under-eye skin improved with the daily use of OS-01 EYE.
How do these results confirm lab findings?
While we were thrilled to learn that OS-01 EYE showed such promising results, we weren’t exactly surprised. Our prior lab research had already established that OS-01 EYE promotes healthy collagen levels. Because collagen is the main structural protein supporting skin elasticity and firmness, our lab data predicted that OS-01 EYE would show these changes even before our clinical tests were performed. In lab studies observing the expression of key biomarkers associated with collagen production (COL1A1), OS-01 EYE was shown to improve a key collagen synthesis biomarker. (5)
The results are the average of testing in 3 different ex vivo eyelid skin samples grown from 42y, 59y, and 84y donors.
But OS-01 EYE doesn’t stop there. Our formula also helps your skin retain its collagen from natural degradation by reducing the expression of (MMP1), a key biomarker responsible for the breakdown of collagen in skin. (5)
The results are the average of testing in 3 different ex vivo eyelid skin samples grown from 42y, 59y, and 84y donors.
To further confirm these results we conducted another study on ex vivo human eyelid samples from a 70-year-old donor. We found that OS-01 EYE increased collagen protein levels by up to 2.3x. (5)
Shown in lab studies on ex vivo human eyelid skin samples (70 yr) by analyzing levels of collagen in skin treated with OS-01 EYE compared to no treatment. Skin treated with OS-01 EYE displayed a significant increase compared to skin with no treatment. Data was measured in triplicate.
This functional increase in collagen levels is likely why OS-01 EYE significantly impacts firmness, elasticity, and overall skin appearance after just a few months of use.

What Long-Term Impacts Can You Expect From OS-01 EYE?
Our products work at the cellular level, so they don’t promise instant results but rather a gradual and lasting improvement in skin. Even so, 12 weeks is a relatively rapid timeline to observe the visible effects of cellular improvements in the skin—all the more reason to be excited about our clinical results being published in a peer-reviewed journal.
Powered by the highest concentration of our OS-01 peptide, OS-01 EYE was formulated to reduce accelerated skin aging around the eyes. Because the OS-01 peptide has been scientifically proven to reverse biological aging by targeting a root cause of skin aging, cellular senescence (4), we believe that OS-01 EYE will continue working to slow and prevent signs of aging like wrinkles, under-eye bags, and more when used consistently.
Anecdotally, our user reviews already reflect this reality, with reports of diminished fine lines, smoother texture, noticeable firmness, and more. You can read more on what our customers have to say about OS-01 EYE hereto learn more about os 01 eye topical supplement.
Key Takeaways:
- Eye area skin shows higher levels of senescent cells and advanced aging, requiring a specialized formula that will target the root cause of skin aging, like the OS-01 peptide.
- Before launching OS-01 EYE, we conducted extensive lab testing to validate its impacts at the cellular level.
- These tests showed that OS-01 EYE increased collagen levels in ex vivo human skin samples by 2.3x, giving us the confidence that our treatment functionally improves under-eye aging.
- We’re happy to report that OS-01 EYE has been proven in clinical studies on human participants to improve firmness, elasticity, and the overall appearance of skin.
- This data confirms what we already suspected: by blocking inflammatory signals from senescent cells and increasing collagen levels in the skin, OS-01 EYE can help the skin resist signs of aging, including skin sagging & laxity.
