SNAP-8

SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that acts as a milder, topical alternative to Botox. It works by inhibiting the SNARE complex, which is involved in neurotransmitter release at the neuromuscular junction. This reduces the intensity of facial muscle contractions, softening expression lines and wrinkles. Applied topically in serums and creams, SNAP-8 offers a non-invasive approach to reducing the appearance of fine lines.
