Topical
5-10% concentration (cream or serum)
Twice daily (morning and evening) · Minimum 28-30 days; ongoing use to maintain effect
Used as a leave-on skin cream or serum. In studies, a 10% formula applied twice a day around the eyes reduced wrinkle depth by about 17% after 15 days and up to 27-30% after 30 days. It works on the skin surface only and is not injected. [1][2]

Topical
4% of supplied trade material in formulation
Twice daily · 28 days for measurable effect, ongoing use
Manufacturer in-vivo study: 4% for 28 days gave ~21% smoother and 15-20% less wrinkled skin [6].

Research compound
Safety overview
Acetyl Hexapeptide-3 demonstrates an excellent safety profile for topical cosmetic use with no serious adverse events reported in clinical studies. At the 10% concentrations used in cosmetic formulations, systemic absorption is minimal and no neurotoxicity has been observed despite its mechanism of action on the neuromuscular junction. The peptide shows a safety margin of approximately 100-fold compared to toxic reference compounds. Primary concerns are limited to local skin irritation in sensitive individuals, such as mild erythema, transient stinging, or contact dermatitis in those with peptide hypersensitivity.
Contraindications
- Known hypersensitivity to acetyl hexapeptide-3 or formulation components
- Active skin infections or open wounds at the application site
- No known systemic contraindications at cosmetic concentrations
- Use with caution in individuals with neuromuscular disorders (theoretical concern)
SYN-AKE
Evidence level
Limited human trials
FDA status
Research compound
Safety overview
SYN-AKE demonstrates excellent topical tolerability with no serious adverse events reported in cosmetic use spanning 15+ years. Adverse testing including Ames test (genotoxicity) and cytotoxicity assays show negative results at therapeutic concentrations, confirming absence of mutagenic or cellular toxicity potential. Occasional mild tingling or slight dryness represents expected local skin responses rather than true adverse effects; systemic absorption is negligible due to peptide topical application mechanism.
Contraindications
- Known hypersensitivity to Dipeptide Diaminobutyroyl Benzylamide Diacetate or excipients
- Active skin infections or significant dermatitis at intended application sites
- Severe compromised skin barrier in the treatment area
- Concurrent use with products at pH above 7.5 that may destabilize the peptide
