About this ingredient
Biotinoyl tripeptide-1 (INCI: Biotinoyl Tripeptide-1) is a synthetic tripeptide bound to a biotin molecule. It is used in anti-aging and hair cosmetics, and the supplier links it to improved firmness and renewal of skin and hair. It deserves a realistic read: most of the data come from the supplier, and independent evidence is thin. It is a supporting active; it contributes inside a well-built formula but is not decisive on its own. Topical biotin plays a limited role, far from the myths around oral use. Topically it is not systemically relevant, so it can be used during pregnancy and breastfeeding without concern. Tolerance is high, with low irritation and allergy potential, suitable for sensitive skin.
