Acetyl Hexapeptide-8 is a synthetic peptide and is frequently used as a neurocosmetic active ingredient. In in vitro studies, it modulates components of the SNARE complex, which can attenuate facial micro-contractions—a mechanism often described as “Botox-like” (a cosmetic, non-injectable mechanism).(1-2)

Clinical trials report a reduction in fine lines. In the eye area, brightening and soothing effects were also observed in areas where the skin appeared tired. Manufacturer data show that the activity of tyrosinase—a key enzyme in melanin production—can be inhibited (in vitro), thereby contributing to a more even skin tone.(3-4)
