What is Acetyl Hexapeptide-1?

Acetyl Hexapeptide-1 is a synthetic peptide made from six amino acids with an acetyl group attached to the N-terminus, designed to resemble parts of alpha-melanocyte-stimulating hormone. Classified as a skin conditioning agent in cosmetics, it appears in serums, creams, and lotions. It works by interacting with cellular receptors on skin cells, particularly melanocytes, to influence melanin synthesis and support skin barrier function. This process helps preserve skin's natural moisture, elasticity, and even tone. Typically incorporated at trace levels, it provides a gentle biotech-derived option for formulations targeting conditioning without heaviness. Its peptide structure enables targeted signaling, promoting suppleness and resilience in daily skincare routines.
