Product Description

Snap-8 (Acetyl Octapeptide-3) is a synthetic peptide derived from the SNAP-25 protein, a key component in the neurotransmitter release mechanism. It is widely used in cosmetic formulations targeting signs of facial aging.

Mechanism of Action:

• Inhibits excessive release of acetylcholine at the neuromuscular junction

• Reduces the intensity of facial muscle contractions

• Softens expression lines, particularly crow's feet and forehead wrinkles

• Offers a milder alternative to neuromodulator agents in cosmetic research

Cosmetic Research Applications:

• Anti-aging formulation development

• Wrinkle reduction studies

• Facial expression line research

• Topical peptide efficacy investigations

Formulation Guidelines:

• Recommended usage level: 2–10% in topical formulations

• Compatible with water-based cosmetic systems

• Stable within typical cosmetic pH ranges (4.5–6.5)

• Can be combined with other anti-aging peptides for synergistic effects

Quality Assurance

• Purity verified by HPLC (≥99%)

• Mass spectrometry confirmation for molecular identity

• Certificate of Analysis (CoA) provided with each shipment

• Microbial testing for cosmetic applications

• Stability data available for qualified manufacturers
