Carolina Reis Oliveira Put a Biotech Lab Behind the Beauty Counter
A Brazilian biochemist crossed from tissue engineering into consumer beauty, then spent five years and 900-plus peptide tests turning laboratory discipline into a direct-to-consumer company.
OneSkin
OneSkin is a San Francisco biotech and direct-to-consumer skincare company founded by four Brazilian women scientists who set out to slow skin aging at the molecular level. Its flagship OS-01 peptide - identified from a library of 900+ candidates using computational screening and tested on lab-grown human skin models - targets senescent 'zombie' cells that drive wrinkles, thinning and loss of firmness. The company sells topical 'supplements' for the face, eyes, body and sun protection, and frames skin not as a cosmetic surface but as the body's largest organ and a lever on overall healthspan.
