Acetyl hexapeptide-4
INCI name · acetyl hexapeptide-4
In short
Acetyl Hexapeptide‑4 is a stabilised form of Hexapeptide‑4 designed to stay active longer on the skin. It supports firmness and texture by engaging collagen‑related signalling pathways.
What it is
N-terminally acetylated form of hexapeptide-4; acetylation at the amino terminus improves metabolic stability against aminopeptidase activity in the stratum corneum, extending the effective concentration reaching fibroblasts; targets the same procollagen I C-terminal receptor pathway as the parent peptide but with an improved half-life in formulation; hydrophilic and compatible with most aqueous systems.
