What is SNAP-8?

SNAP-8 is a cosmetic peptide that works by a mechanism similar to botulinum toxin (Botox) but in a much milder, topical form. It is an octapeptide that competes with SNAP-25 for a position in the SNARE complex, which is involved in neurotransmitter release at the neuromuscular junction. By modulating this process, it may reduce muscle contraction intensity and thereby reduce the appearance of expression lines.

Preliminary

How It Works

SNAP-8 works by gently interfering with the signals that cause facial muscles to contract. By reducing the intensity of these contractions, it may help soften the appearance of expression lines over time. Think of it as a very mild, topical version of the Botox concept.
