snap-8

SNAP-8 is a synthetic neuropeptide (octapeptide) widely used as a topical ingredient in high-end cosmetic and anti-aging skincare products. Marketed as a “Botox-like” alternative, it works by locally modulating muscle contraction. Its primary function is to reduce the depth of facial expression wrinkles (dynamic wrinkles) by disrupting the release of the neurotransmitter acetylcholine at the nerve-muscle junction, leading to muscle relaxation without the need for injections.
