A biotin-linked tripeptide used to support the look of stronger, fuller, better-conditioned hair.

How It Works

The peptide fragment provides a targeting sequence while the linked biotin lends a hair-associated cofactor; together they are used to support the visible signs of hair strength and condition. Its benefits are described at the level of the appearance and feel of hair, not as a medical or hair-growth treatment.

Formulating with Biotinoyl Tripeptide-1

Biotinoyl Tripeptide-1 is water-soluble and added to the water phase, typically at cool-down and at low levels to protect its actives. It pairs well with other actives and humectants. Observe good manufacturing and preservation practice.

Safety Analysis

Biotinoyl Tripeptide-1 is well tolerated at cosmetic use levels. Claims are limited to the appearance and feel of hair. As always, substantiate the finished product’s safety (e.g. patch / HRIPT testing) in line with MoCRA requirements.
