THIS IS NOT AN ORDINARY MOISTURIZER
Most moisturizers do one thing — sit on the surface of your skin and slow down water loss. They feel good. Some even look good. But they don’t change anything about how your skin is actually aging at a cellular level.
OneSkin BODY OS-01 is a completely different category of product. It’s called a Topical Supplement — and that distinction matters. It was developed by a team of longevity scientists who set out to answer a specific question: what if you could slow down, and even reverse, the biological aging of your skin from the outside?
After years of research, peer-reviewed publications, and clinical studies, their answer is the OS-01 peptide — and the results are unlike anything the skincare industry has seen before.

THE SCIENCE — WHAT IS SKIN SENESCENCE?
───────────────────────────────────────────────
Here is the concept that drives everything OneSkin does.
As we age, some of our skin cells stop dividing and enter a state called senescence. These senescent cells — sometimes called zombie cells — don’t die off the way they should. Instead, they accumulate in the skin and release inflammatory signals that damage the healthy cells around them. This is one of the core biological mechanisms driving visible skin aging: thinning, crepey texture, loss of elasticity, and slower wound healing.
The OS-01 peptide was specifically designed to reduce the burden of these senescent cells in skin. Published research in the peer-reviewed journal npj Aging showed that the OS-01 peptide measurably reduces senescence in human skin models — making it one of the first skincare actives with published evidence of actually addressing a root biological cause of skin aging rather than just masking the appearance of it.

WHO IS ONESKIN BODY OS-01 FOR?
───────────────────────────────────────────────
This product is designed for adults who want to address the actual biology of skin aging — not just the surface appearance. It may be right for you if:
✓ You have thinning, crepey, or dry skin on the body — especially arms, legs, and neck
✓ You are interested in longevity science and want a skincare product backed by published research
✓ Your current body moisturizer hydrates but doesn’t seem to improve skin quality over time
✓ You have sensitive skin and need a completely fragrance-free, clean formula
✓ You are in your 40s, 50s, or beyond and want to address visible body skin aging
✓ You want a moisturizer developed by scientists with peer-reviewed publications — not a marketing team
Good to know: The 250ml bottle lasts approximately 1 to 2 months with daily use on the body as directed. OneSkin also offers a FACE version formulated specifically for facial skin — the body formula is designed for optimal absorption through the thicker skin on the body and is not recommended for the face.

WHAT IS INSIDE THIS FORMULA?
───────────────────────────────────────────────
OS-01 Peptide (Decapeptide-52)
The star ingredient — a proprietary peptide developed and patented by OneSkin scientists. Shown in peer-reviewed studies to reduce senescent cell burden in human skin models and reduce the biological age of skin as measured by epigenetic DNA methylation analysis.
Ceramide NP
One of the essential lipids that form the skin’s natural barrier. Ceramides are known to decline with age, and restoring them topically is one of the most evidence-based strategies for repairing skin barrier function and reducing moisture loss.
Centella Asiatica Extract and Asiaticoside
A well-studied botanical with anti-inflammatory, wound-healing, and collagen-stimulating properties. Widely used in dermatology for its ability to calm irritation and support skin repair.
Hyaluronic Acid (Sodium Hyaluronate Crosspolymer)
A next-generation cross-linked hyaluronic acid that binds moisture more effectively than standard hyaluronic acid and penetrates deeper into the skin layers.
Niacinamide
Clinically proven to improve skin texture, even skin tone, reduce pore appearance, and support the skin barrier. One of the most versatile and well-researched actives in modern skincare.
Tremella Fuciformis (Mushroom) Extract
A powerful natural humectant shown to hold moisture even more effectively than standard hyaluronic acid — known as the beauty mushroom in traditional medicine for its skin-plumping properties.
Sulforaphane and Centella Asiatica
Additional antioxidant and anti-inflammatory actives that support the skin’s natural defenses against environmental and oxidative stress.

OUR REVIEW: ONESKIN BODY OS-01 PEPTIDE 250ML
───────────────────────────────────────────────
Rating: ★★★★½ 4.5/5 — Verified Amazon Reviews
What separates OneSkin from every other body moisturizer on the market is that the science behind it has been independently peer-reviewed and published. Most skincare brands run their own internal studies. OneSkin published their research in npj Aging — one of the most respected journals in longevity science — and had their clinical trial published in the Journal of Cosmetic Dermatology. That is a completely different level of scientific accountability.
The texture itself is a rich but lightweight lotion — not greasy, not heavy, absorbs well even on the legs and arms where thicker products can feel uncomfortable. The fragrance-free, clean formula makes it suitable even for people who have had reactions to conventional body lotions.
WHAT WE LOVE:
✓ Peer-reviewed published research — not just internal brand studies
✓ Up to 40% increase in epidermal thickness
✓ Strengthens skin barrier by up to 41%
✓ Rich formula that absorbs without greasiness
✓ 100% fragrance-free and free from 15+ common irritants
✓ Developed by longevity scientists — not a marketing team
✓ Suitable for sensitive skin — dermatologist tested
✓ Generous 250ml size — lasts 1 to 2 months
KEEP IN MIND:
✗ Premium price point for a body moisturizer
✗ Do not use on the face — a separate FACE version exists for that
✗ Results build over consistent daily use
✗ Not a replacement for professional dermatological treatment

HOW TO USE IT — STEP BY STEP
───────────────────────────────────────────────
Step 1 — Apply to clean skin
Use after showering or bathing while skin is clean. Can be applied to dry or slightly damp skin — both work well with this formula.
Step 2 — Apply a generous layer
This is a body product, so apply generously to all areas of concern — arms, legs, chest, neck, and any areas with dry, thin, or crepey skin. Do not apply to the face.
Step 3 — Massage until absorbed
Massage in with circular motions until the lotion is fully absorbed. It sinks in relatively quickly without leaving a heavy residue.
Step 4 — Use once or twice daily
For best results, apply once or twice daily consistently. The peer-reviewed results are based on regular daily use over time.
Step 5 — Store at room temperature
Keep away from direct sunlight. The shelf life is 24 months and no refrigeration is needed.

FREQUENTLY ASKED QUESTIONS
───────────────────────────────────────────────
What makes this different from a regular body lotion?
Most body lotions hydrate the skin surface without affecting how the skin ages at a cellular level. OneSkin BODY OS-01 contains a patented peptide with published peer-reviewed evidence of reducing senescent cells in skin — addressing one of the biological root causes of aging rather than just moisturizing the surface.
What are senescent cells and why do they matter for skin aging?
Senescent cells are cells that have stopped functioning normally but have not died off. They accumulate with age and release inflammatory signals that damage surrounding healthy skin cells — contributing to thinning, loss of elasticity, slower healing, and crepey texture. The OS-01 peptide targets this process specifically.
Can I use this on my face?
No. OneSkin specifically formulated the BODY version for optimal absorption through the thicker skin on the body. A separate OS-01 FACE version is available and formulated for facial skin.
How long before I see results?
Improvements in hydration can be noticed quickly — often within the first week. More significant changes in skin thickness, texture, and barrier strength build over several weeks to months of consistent daily use.
Is this safe for people with very sensitive skin?
Yes — the formula is fragrance-free, paraben-free, sulfate-free, gluten-free, and PFA-free. It has been dermatologist tested and designed specifically to be safe for sensitive skin. A patch test is always a good idea with any new product.
