SNAP-8

A synthetic octapeptide that mimics the N-terminal end of SNAP-25, a key protein in the SNARE complex responsible for neurotransmitter release. By competing with native SNAP-25, SNAP-8 reduces the exocytosis of neurotransmitters at the neuromuscular junction, resulting in decreased muscle contraction and reduced expression lines — often called a 'topical Botox alternative.'

• Competes with SNAP-25 for position in the SNARE complex
• Reduces vesicle fusion and acetylcholine release at the neuromuscular junction
• Decreases muscle contraction intensity in treated facial areas

• Known allergy to peptide ingredients
• Open wounds or active skin infections at application site
• Use with caution alongside botulinum toxin injections (additive effect)

Store at room temperature (15–25°C (59–77°F)) away from direct sunlight. Use within manufacturer's recommended timeframe after opening.

Developed by Lipotec (now part of Lubrizol), SNAP-8 has been shown in in vitro studies to reduce SNARE complex formation by up to 40%. Clinical studies on volunteers demonstrated a 63% reduction in wrinkle depth after 28 days of twice-daily application at 10% concentration. It is an extension of the argireline (Acetyl Hexapeptide-3) concept with two additional amino acids for improved efficacy. Widely used in premium cosmeceutical formulations globally, though it does not replace neurotoxin injections for deep wrinkles.
