Biotinoyl Tripeptide-1 is a bioactive peptide derived from a combination of biotin (vitamin B7) and a tripeptide (Glycyl-Histidyl-Lysine). It is widely used in cosmetic and dermatological formulations, particularly in hair care and eyelash/eyebrow growth products.
This ingredient works by strengthening hair follicles and improving scalp microcirculation, which helps support healthier and stronger hair growth. The biotin component provides essential nutrients for keratin production, while the tripeptide portion helps stimulate cellular activity and follicle anchoring.
