Key Benefits

Basically, it's a treatment that happens to feel like a balm. Smooth OS-01 Lip Mask on before bed and let it do its thing while you sleep. Come morning, lips feel soft, smooth, and actually replenished, not just sitting under a layer of product. That's thanks to the proprietary OS-01 Peptide™, which supports the biomarkers behind collagen, elastin, and hyaluronic acid. Stick with it and lips start looking firmer, plumper, and bouncier the longer you use it.

Microalgae, ceramides, and squalane pitch in to strengthen the lip barrier and hold onto moisture all night long. Astaxanthin, an algae antioxidant that's doing more work than you'd expect, gives the balm its soft rosy tint and leaves lips looking smoother and more awake by morning. Palmitoyl hexapeptide-12 teams up with OS-01 Peptide™ to support elasticity, so lips feel firmer and healthier the more you use it.

It's dermatologist-tested, fragrance-free, and gentle enough even for sensitive skin. The formula's vegan, made with sustainably sourced ingredients, and leaves out parabens, sulfates, lanolin, MCI/MI, DEA, heavy metals, talc, petrolatum, mineral oil, gluten, phthalates, PFAs, and anything else your lips really don't need.

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.
