Acetyl Tetrapeptide-17
What is Acetyl Tetrapeptide-17?
Acetyl Tetrapeptide-17 is a synthetic signal peptide formed by linking four amino acids, with an acetyl group attached to enhance stability and skin penetration. It falls under cosmetic peptides designed for targeted action. Commonly found in hair care formulations like shampoos, serums, and scalp treatments, it serves as a conditioning agent for both skin and hair according to regulatory databases. In products, it works by reaching the dermal papilla in hair follicles, where it influences cellular activity to bolster structural proteins that anchor hair roots. This mechanism supports its role in maintaining hair integrity without altering growth cycles. The ingredient is typically solubilized in aqueous phases and remains stable across a range of pH levels in cosmetic blends, making it versatile for rinse-off and leave-on applications.
