Acetyl Octapeptide-3 Buono Peptide Anti-age Idratare Acetyl Octapeptide-3 description Synthetic peptide that is based around octapeptide-3, a peptide complex composed of the amino acids aspartic acid, glutamic acid, glutamine, and methionine. Also known as SNAP-8, this peptide is said to improve the look of signs of ageing formed from repetitive facial expressions, though there’s no independent research supporting this claim. Even if there were independent research, the concentrations used in the company-sponsored testing to support the improvement of signs of ageing was 3-10%, which is far greater than what’s typically present in skin care products. Like all peptides it has water-binding properties and theoretical skin-restoring ability. It may play a role in helping skin look younger, and can help hydrate and smooth skin.
