The OS-01 LIP SPF is a daily mineral lip treatment designed to protect, hydrate, and care for your lips. Powered by the brand’s proprietary OS-01 Senescence Blocking Peptide™, the first peptide scientifically proven to target a root cause of skin ageing, it helps support the lips’ natural barrier and hydration, keeping it smooth and more resilient. It provides 100% mineral SPF 15+ protection with non-nano zinc oxide, helping to prevent UV-induced damage, inflammation, and collagen loss. 

It also blends skin-supportive ingredients like Vitamin E that help defend against environmental stressors while keeping lips soft and supple. Vitamin C (Tetrahexyldecyl Ascorbate), a stable antioxidant form, supports collagen and helps brighten dullness. Bisabolol and Centella Asiatica Extract calm and strengthen the delicate lip barrier, while Sea Buckthorn Oil replenishes moisture and restores elasticity. 

Vegan, lightweight, fragrance-free, and dermatologically tested, OS-01 LIP SPF delivers lasting hydration and protection, leaving lips soft, supple, and cared for every day.

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.
