Acetyl Octapeptide-3 is a cosmetic ingredient that can significantly reduce facial wrinkles, especially in the forehead and periocular area. By blocking the binding site of the SNAP-25 protein, the ingredient inhibits muscle contraction, thereby effectively preventing the formation of wrinkles. As an alternative to botulinum toxin type A, acetyl octapeptide-3 not only provides similar effects, but also avoids the high cost and inconvenience of injection therapy.
