In the field of cosmetics, Biotinoyl Tripeptide-1, known as a lash peptide, stands out for its ability to improve the appearance and health of eyelashes. This bio-fermented ingredient, combined with provitamin B5, stimulates the proliferation of keratinocytes in the hair follicle and strengthens hair attachment through the synthesis of laminin 5 and collagen IV. Clinical studies have shown that it increases eyelash length by 43% and thickness by 40% after 30 days of use, making it an essential ally for longer, denser, and stronger eyelashes.
