Acetyl Tetrapeptide-3 is a synthetic bioactive peptide composed of four amino acids with an acetyl group attached, designed to enhance stability and biological activity in cosmetic formulations. It is widely used in hair care and scalp treatment products, particularly for hair strengthening and hair loss prevention formulations.
This peptide works by stimulating the synthesis of extracellular matrix proteins in the scalp and strengthening the dermal papilla and hair follicle anchoring structure. By improving the environment around the hair follicle, it helps promote stronger, thicker, and healthier hair growth.
