SNAP-8 is generally identified in cosmetic ingredient terminology as acetyl octapeptide-3.The name reflects its structure: “acetyl” refers to the attached acetyl group, while “octapeptide” indicates that the peptide contains eight amino acids.
It is sometimes described in consumer products as an “acetyl hexapeptide serum,” but this terminology can lead to confusion with Argireline, which is commonly associated with acetyl hexapeptide-8 and, in some older ingredient references, acetyl hexapeptide-3. Although SNAP-8 and Argireline are both cosmetic peptides often discussed for their wrinkle-related applications, they are different ingredients and should not be considered interchangeable.
