Regulatory statusCosmetic; not approved injectable
What you need to know in 20 seconds
What is it?
Synthetic cosmetic octapeptide
Research focus
Topical cosmetic wrinkle research
Human evidence
Human cosmetic studies of microneedle formulations containing acetyl octapeptide-3 report wrinkle/skin-quality improvements, but the studied products also contained other active ingredients.
Regulatory status
Cosmetic ingredient rather than an approved injectable therapeutic.
Main limitations
The independent effect size, injectable efficacy, or long-term therapeutic benefit of acetyl octapeptide-3 alone.
Safety
Systemic/injectable safety is not established and should not be inferred from cosmetic topical use.
i
Human cosmetic studies of microneedle formulations containing acetyl octapeptide-3 report wrinkle/skin-quality improvements, but the studied products also contained other active ingredients.
What the evidence actually supports
✓Phrase as 'formulations containing SNAP-8 have been studied' rather than 'SNAP-8 proven to reduce wrinkles'.
✓Grade the formulation evidence separately from isolated-compound efficacy.
What is not established / key limitations
×No clean standalone ingredient RCT identified in this pass.
×The studies do not isolate acetyl octapeptide-3 as the sole active ingredient.
Systemic/injectable safety is not established and should not be inferred from cosmetic topical use.
Topical cosmetic exposure is the relevant evidence context; systemic/injectable safety is not established.
Technical details
Mechanism / biologyDesigned as a cosmetic peptide intended to influence SNARE-associated neurotransmitter-release pathways at the skin surface.
Route / formulation boundaryProduct-level effects from multi-active microneedle formulations cannot be attributed wholly to acetyl octapeptide-3.
Identity / data-quality noteUse the canonical compound identity and studied formulation when interpreting evidence.
Dosing evidence statusDosing research conclusion recorded. A human cosmetic study used a multi-ingredient microneedle product, so an isolated acetyl octapeptide-3 dose-response cannot be assigned.
