About
A synthetic four-amino-acid peptide conjugated to biotin (vitamin B7) — used as a skin-conditioning active. Low-risk by class.
Biotinoyl Tetrapeptide-51 is a synthetic tetrapeptide chemically modified by attaching biotin (vitamin B7), intended to combine peptide carrier behavior with biotin-related skin/hair benefits. Both biotin and short peptides are well tolerated topically at typical cosmetic levels. There is no specific CIR or SCCS opinion for this conjugate. Independent peer-reviewed efficacy data is essentially absent; claims rely on supplier in vitro work and small consumer panels.
