Acetyl Heptapeptide-4
What is Acetyl Heptapeptide-4?
Acetyl Heptapeptide-4 is a synthetic bioactive peptide made from a sequence of seven amino acids with an acetyl group at the N-terminus, modeled on thymopentin from the thymus gland. In cosmetics, it acts as a skin conditioning and protecting agent. It functions by signaling keratinocytes to boost synthesis of human beta-defensins, natural antimicrobial peptides integral to the skin's innate immune response. This contributes to barrier maintenance and resilience against daily stressors. Commonly found in serums, creams, and lotions for facial care, it is water-soluble, stable, and used at trace levels to enhance formulation efficacy without impacting sensory qualities. Its peptide nature allows targeted cellular communication in topical applications.
