OS-1 FACE Topical Supplement

OneSkin’s products harness the power of OS-01, an innovative peptide that tackles skin’s biological age by zeroing in on senescent cells—often referred to as "zombie" cells that speed up the ageing process. As these damaged cells accumulate, they lead to wrinkles, loss of firmness, and thinning skin. The OS-01 peptide works by actively repairing DNA damage in these cells, stopping them from unleashing harmful pro-aging factors that can impact surrounding healthy cells. This groundbreaking approach reduces cellular senescence, effectively lowering the skin’s biological age. It also boosts biomarkers of healthy skin, including collagen and hyaluronic acid biosynthesis to promote a healthier, more youthful skin that stays resilient over time.

Founded by a team of four female PhDs, OneSkin's products focus on skin longevity. At the core of their products is OS-01, the only peptide scientifically proven to reverse skin aging at the molecular level. OneSkin's approach goes beyond aesthetics, focusing on keeping skin healthier and more resilient over time. With rigorous research, peer-reviewed data, and a passion for life, the brand is redefining ageing and empowering individuals to live without limits.
