SNAP-8, also known as acetyl octapeptide-3, is a peptide used in anti-aging skin care treatments. It’s a more potent analog of acetyl hexapeptide-8, also known as Argireline. SNAP-8 has the amino acid sequence Unk-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2 and molecular formula C42H72N16O15S. Though it’s known for its skincare applications, this peptide’s anti-aging activities work by modulating the release of neurotransmitters [1]. Scientific Studies In a study published in the International Journal of Cosmetic Science, healthy women were administered SNAP-8 for 30 days. After skin topography analyses were conducted, the results showed a reduction in wrinkles up to 30 percent. According to the study’s authors, SNAP-8’s mechanism of action mimicked Botulinum neurotoxins (BoNTs) without exerting their neurotoxic effects [2]. Like Botox, SNAP-8 inhibits any neurotransmitters signalling muscles to contract. With less contraction, wrinkles in skin become less deep over time.
