This synthetic peptide is based on octapeptide-3, a peptide composed of the amino acids aspartic acid, glutamic acid, glutamine, and methionine. Like all peptides, it has moisture-binding properties and theoretical skin-repairing abilities. It can help skin appear younger and can help moisturize and smooth the skin.

Acetyl Octapeptide-3 (SNAP-8) is a more potent anti-aging peptide than Acetyl Hexapeptide-3. Acetyl Hexapeptide is more stable than botulinum toxin and can effectively reduce facial wrinkles.
