OUR BREAKTHROUGH PEPTIDE
OS-01: the new standard in peptide technology
Think of OS-01 as a reset button for your skin, helping clear away the senescent cells that cause wrinkles, hyperpigmentation, and crepiness. As the first peptide scientifically proven to reduce cellular senescence in the skin, OS-01 does what other peptides can’t. 01

“Deep Hydration, Stronger Skin: Powered by OS-01 Peptide”
Experience hydration that goes beyond the surface. This visual captures what OS-01 BODY does at a cellular level — delivering moisture deep into the skin while strengthening the barrier for long-lasting resilience. Formulated with the patented OS-01 peptide, our body topical supplement supports firmer, smoother, more youthful-looking skin from the inside out. Lightweight, fast-absorbing, and backed by science, it keeps your skin healthy, hydrated, and radiant every day.
“Skincare for Every Body. Powered by Science.”
Healthy, resilient skin belongs to everyone. This image captures the essence of OS-01 — a formula designed for all genders, all skin types, and all stages of life. Our patented OS-01 peptide works at the cellular level to support firmer, smoother, more hydrated skin, helping you feel confident in your natural glow. Because real results aren’t about age or labels — they’re about science that works for every body.
“Targeted Science. Visible Skin Renewal.”
This image represents the power of OS-01 — a patented peptide engineered to reach the skin where it matters most. Encapsulated for stability and precision, the molecule works deep within the skin’s surface to support cellular repair, strengthen the barrier, and promote smoother, firmer, more resilient skin. With every application, OS-01 delivers science-backed performance your skin can feel and you can see.
OUR LEADERSHIP TEAM
Four scientists on a mission to redefine aging
As scientists with PhDs in skin regeneration, stem cell biology, immunology, and bioinformatics, our journey began with a simple question: Are any of the so-called anti-aging products on the market actually effective? To our surprise, most didn’t promote true rejuvenation. And when we evaluated them in the lab, we discovered that some were even harmful at the cellular level.
That’s when we rolled up our sleeves and got to work. After more than 5 years of research and screening over 900 peptides, we developed OS-01 – the first ingredient scientifically proven to reverse skin’s biological age. By targeting cellular senescence (one of the key drivers of skin aging), OS-01 helps switch off damaged cells that contribute to lines, wrinkles, and sagging skin.
But our vision was never just about appearance. We started OneSkin to enhance how skin functions, so it stays healthier and more resilient as you age. Think of it as a long-term fitness plan for your skin. As your body’s largest organ, it’s crucial to make skin health part of your overall approach to longevity — one that we believe also includes nutrient-dense foods, consistent exercise, stress management, and mental and emotional well-being.
Good health is about feeling unstoppable, inside and out. That’s what drives us. Through our rigorous R&D process, peer-reviewed data, passion for life, and insatiable curiosity, we’re redefining expectations around aging, empowering you with the knowledge to make your own choices and enjoy life without limits.

❓ Frequently Asked Questions
What is OS-01 BODY and how does it work?
What is OS-01 BODY and how does it work?
OS-01 BODY is a body topical supplement powered by the proprietary OS-01 peptide, which targets one of the root causes of skin aging — cellular senescence. Its action helps reduce the number of senescent (aging) skin cells, supports healthier skin cell function, and promotes increased epidermal thickness and barrier strength.
What benefits can I expect from regular use?
What benefits can I expect from regular use?
With consistent daily use, OS-01 BODY is shown to boost skin barrier function, increase hydration, improve smoothness and firmness, and support healthier-looking, more resilient skin from neck down. In lab studies on human skin samples, treatment with OS-01 BODY resulted in up to ~40% increase in epidermal thickness compared to untreated skin — a key marker of skin barrier health.
How do I use OS-01 BODY and how often?
How do I use OS-01 BODY and how often?
Apply OS-01 BODY topically to areas like arms, legs, chest, back, and torso. Massage until absorbed. For best results, use twice daily (morning and night) on clean skin.
Can I use OS-01 BODY if I have sensitive skin?
Can I use OS-01 BODY if I have sensitive skin?
Yes — OS-01 BODY is formulated to be gentle and suitable for most skin types. It’s free from parabens, sulfates, and unnecessary additives, and does not rely on harsh exfoliants or irritants.
How is OS-01 BODY different from a regular moisturizer?
How is OS-01 BODY different from a regular moisturizer?
Unlike standard moisturizers that mainly hydrate or temporarily improve the skin’s surface, OS-01 BODY works at the cellular level to address aging mechanisms. It helps reduce senescent cells, improves barrier function, and supports long-term skin health — going beyond simple moisture to promote true “skin longevity.”
