Discover OS-01 FACE SPF 30+, a daily mineral sunscreen and moisturiser designed to protect your skin from UV rays, free radicals, blue light, and cellular ageing. Powered by the brand’s proprietary OS-01 Senescence Blocking Peptide™, it helps address the signs of ageing at their root by supporting the skin’s natural barrier and hydration.

Formulated with non-nano zinc oxide, it provides broad-spectrum SPF 30+ protection while delivering a soothing, antioxidant-rich boost to the skin. The blend includes Vitamin C to support collagen and elastin for firmer, brighter skin, and Green Tea Extract, rich in EGCG, offering up to 100 times the antioxidant power of Vitamin C to defend against oxidative stress. Açaí Extract helps protect against pollution and other ageing accelerators, while Tara Fruit and Sunflower Sprout Extracts work together to neutralise free radicals and help preserve skin elasticity. Finally, Bisabolol calms and comforts, reducing irritation and leaving skin feeling balanced and smooth.

Dermatologist tested, non-comedogenic, fragrance-free, and safe for sensitive skin, OS-01 FACE SPF 30+ keeps skin calm, hydrated, and protected 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.

Gently massage into skin in thin layers, allowing it to absorb before adding more (this will minimize white cast).

Use 15 minutes prior to sun exposure and reapply every two hours.
