Acetyl Octapeptide-3
What is Acetyl Octapeptide-3?
Acetyl Octapeptide-3 is a synthetically produced peptide made up of eight amino acids, featuring an acetyl group attached to the N-terminal end. It falls under neuromodulating peptides commonly found in anti-aging cosmetics like serums, creams, and treatments for the face and eye area. In skincare products, it functions by acting as a synthetic fragment similar to part of the SNAP-25 protein. This allows it to compete for positions in the SNARE complex at nerve endings, thereby decreasing the exocytosis of acetylcholine, the neurotransmitter that triggers muscle contractions. With reduced muscle activity, it addresses dynamic wrinkles caused by repetitive facial expressions, such as those around the eyes and forehead. It integrates well into water-based formulas and is valued for its targeted action in topical applications.
