OneSkin Skin longevity powered by the OS-01 Peptide™—our breakthrough peptide engineered to reverse skin’s biological age.

We use data-driven science to achieve revolutionary products. Sound science is only performed if based on integrity, courage to break paradigms, collaboration and trust. Those values are in our DNA, guiding everything we do.

Skin aging doesn’t happen cell by cell. It spreads.
When a skin cell becomes senescent, often called a “zombie cell,” it stops functioning normally but doesn’t die. Instead, it releases inflammatory factors and tissue-breaking enzymes that push neighboring healthy cells into that same dysfunctional state. One senescent cell becomes several. Several becomes a cascade.
That’s how a small, localized issue turns into visible aging across the skin: inflammation builds, repair slows, and the surrounding tissue ages faster than it should.

The OS-01 Peptide™ works by penetrating the top layers of skin to help healthy, younger cells multiply. It strengthens the skin barrier and reactivates collagen production, restoring skin health so it looks and behaves like younger skin.

“By preventing senescent cells from releasing pro-aging factors, we can prevent healthy cells from becoming zombies, containing the spread of senescence and slowing down skin aging.”

Using PREP FACE CLEANSER can improve OS-01 Peptide™ absorption by 2.2x.¹

The OS-01 Peptide™ can only do its job on skin that’s ready for it.
Oils and daily buildup sit on the surface and block absorption, no matter how good the formula underneath is. PREP FACE CLEANSER gently exfoliates and clears that buildup, so OS-01 FACE MOISTURIZER can actually reach the skin instead of sitting on top of it.
Skip this step, and you’re not getting the full value of what’s already in your routine.

OS-01 FACE MOISTURIZER is built around our proprietary OS-01 Senescence-Blocking Peptide™, which visibly slows cellular skin aging so skin feels and performs younger over time.
In clinical testing, 100% of participants showed visibly smoother texture after 12 weeks, and 96% saw more even tone, radiance, and firmness in that same window.¹

Does your moisturizer have the same rigor behind it?

Did you know? The skin around your eyes can be decades older than the rest of your face.

Thinner skin, less collagen and elastin to start, fewer oil glands, and constant movement from expressions add up to skin that shows signs of aging first, and often earliest.

OS-01 EYE CREAM is built around the same OS-01 Peptide™ used across our line, targeting the senescent cells behind that breakdown while supporting the collagen production that keeps the eye area firm.

Meet the OS skin longevity protocol: consistency over complexity.
Most skincare just improves the visible signs of aging. OneSkin goes deeper, targeting the underlying biology so skin stays healthier, stronger, and more resilient for longer. That kind of change isn’t built overnight. It’s built through advanced science translated into superior, foundational formulas designed to work together as one buildable protocol.

Adding this to the routine and not going back.

OS-01 HAIR SCALP SERUM is the only scalp formula powered by the OS-01 Peptide™, scientifically proven to target senescent cells, the same dysfunctional cells that disrupt healthy hair growth over time.
