As the first peptide scientifically proven to reduce cellular senescence in the skin, OS-01 does what other peptides can’t. 01 Discover the science 6 visible signs of senescence Lines and wrinkles Caused by a decline in collagen and elastin production. Loss of elasticity Decreased elastin also contributes to lack of firmness. Uneven skin tone Irregular melanin production leads to hyperpigmentation. Rough texture Compromised skin cell renewal leaves a dry, uneven surface. Loss of volume Linked to a decrease in hyaluronic acid, collagen, and elastin. Thinning skin Slower cell turnover contributes to a weakened skin barrier.

Frequently Asked Questions

Peptides are short chains of amino acids. They represent a broad class of molecules with many jobs, from forming the building blocks of larger proteins to acting as cellular messengers. Peptides found naturally in the body (called endogenous peptides), play a crucial role in tissue growth, hormone regulation, and other biological processes.

Exogenous peptides, which can be injected, ingested or delivered topically like OS-01, can send out signals to skin cells to trigger collagen and hyaluronic acid production, aid in cellular repair, and help strengthen the skin barrier.01,02,03 OS-01 reduces the accumulation of senescent cells. These cells release inflammatory chemicals that cause neighboring cells to become dysfunctional, kicking off a domino effect in skin and accelerating skin aging. By reducing this inflammatory response, OS-01 helps prevent the accumulation of senescent cells in skin, improving key skin aging biomarkers and keeping other skin cells healthy and thriving.01,02,03 OneSkin is for everyone.

Whether you’re taking a preventative approach or want your skin’s health and appearance to reflect how you feel on the inside, our scientifically proven products work at the cellular level to keep your skin looking, feeling, and acting younger and healthier as you age.01,02,03 Through lab studies and clinical studies, our products have been shown to combat the visible and invisible signs of aging, from collagen loss and thinning skin to a compromised barrier function.01,02,03 To learn more about the specific benefits of each product, visit oneskin.co/claims. With daily use, you can expect to see visible results within 12 weeks, though some people see changes even sooner. This time frame allows OS-01 to work at the cellular level, improving the long-term health and appearance of your skin.01,02,04 01 Zonari, A., et al.
