- Molecular Identity
- Eight-amino-acid synthetic peptide sequence (Acetyl-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2)
- Identical eight-amino-acid synthetic peptide. Same sequence
- No structural difference. Both names reference the same compound
- Naming Convention
- Trademarked brand name developed by Lipotec (Lubrizol)
- INCI (International Nomenclature of Cosmetic Ingredients) designation
- SNAP-8 used in branded formulations; acetyl octapeptide-3 used on ingredient labels and in generic formulations
- Mechanism of Action
- Competitive inhibition of SNARE complex assembly by mimicking SNAP-25 protein fragment
- Identical. Inhibits SNARE complex assembly through SNAP-25 fragment mimicry
- Mechanistically indistinguishable. Both reduce neurotransmitter vesicle docking efficiency at the neuromuscular junction
- Regulatory Status
- Not FDA-approved as a drug. Classified as a cosmetic ingredient under 21 CFR 700
- Same regulatory classification. Cosmetic ingredient, not pharmaceutical
- Neither requires prescription; both fall under cosmetic ingredient oversight rather than therapeutic drug regulation
- Typical Use Concentration
- 5–10% in topical formulations for wrinkle reduction
- Same concentration range. 5–10% for comparable efficacy
- Dosing protocols identical regardless of nomenclature used on the label
- Clinical Efficacy Data
- 10% SNAP-8 formulations reduced wrinkle depth by 63% at 28 days in published trials
- Same clinical data applies. Efficacy tied to peptide concentration, not brand name
- No performance difference when concentration and formulation base are held constant
