OneSkin: a breakthrough line of skin health products powered by longevity science to address the root causes of aging. While many skincare brands make claims about reversing aging, OneSkin is the first company that quantifies the age reversal effect of their products by measuring changes in the skin at the molecular level. By researching the main driver of skin aging, OneSkin developed a new and proprietary peptide, OS-01, which powers OneSkin products. OS-01 is the first peptide proven to reverse aging by reducing the accumulation of aged senescent cells in human skin models. The result? Healthier, biologically younger, more resilient skin for better overall health and longevity.
