SNAP-8 (Acetyl Octapeptide-3) is a popular, topical anti-aging peptide used in skincare as a milder, non-invasive alternative to Botox. It works by mimicking the N-terminal end of SNAP-25, disrupting neuromuscular signaling to relax facial muscles and smooth out expression lines and wrinkles.
How It Works
- Muscle Relaxation: Inhibits the release of neurotransmitters that cause repetitive facial contractions, preventing the deepening of dynamic wrinkles.
- Target Areas: Most effective on expression lines caused by smiling or squinting, such as crow’s feet and forehead creases.
- Formulation: Usually sold as a serum booster or pre-formulated into creams and lotions at concentrations between 2% and 10%.
