SNAP-8 is an eight-amino-acid peptide designed to reduce the appearance of wrinkles, specifically by targeting the same mechanism as botulinum toxin. It is typically formulated into topical creams, serums, or patches. Dosing involves calculating the precise active peptide concentration within a cosmetic research formulation rather than a direct injection amount.
- SNAP-8 is Acetyl Octapeptide-3, an 8-amino acid peptide.
- Dosage is expressed as a concentration in a final topical product.
- Typically used at 0.0015% to 0.005% active peptide.
- Research evaluated use in creams, multi-peptide serums, and microneedle patches.
- A 10 mg vial can make 200g of a 0.005% active formulation.

Dosing schedule
| Phase | Dose | On a U-100 syringe |
|---|---|---|
| Weeks 1-4 (Cream) | 0.005% active peptide | Apply twice daily around the eye area |
| Weeks 1-12 (Serum) | Multi-peptide serum with SNAP-8 | Apply morning and evening |
| Weeks 1-4 (Patch) | 0.03% SNAP-8 patch | Overnight nightly for 14 days, then every third day through day 28 |
Protocol detail
| Confirm Active Mass | Adjust the nominal 10 mg amount if the lot assay requires it. |
|---|---|
| Select Research Concentration | Target between 0.0015% and 0.005% active SNAP-8 in the final product. |
| Calculate Peptide Mass Needed | Use the formula: Peptide mg needed = target percent multiplied by final batch grams multiplied by 10. |
| Prepare and Mix | If direct mass measurement is too low, use an accurately quantified stock solution. Ensure uniform dispersion in the chosen base (cream, gel, or serum). |
| Verify and Label | Record final weight, pH, appearance, packaging, and dispensing amount. Label with concentration, batch ID, and date. |
Overview at a glance
| Developer Active Reference Range | Approximately 0.0015% to 0.005% active SNAP-8 |
|---|---|
| Best Documented Cream Example | Approximately 0.005% active SNAP-8, applied twice daily for 28 days. |
| Formulation Note | When a 10 mg vial is used in a 200 g batch, it yields a 0.005% w/w concentration. |
How it works
SNAP-8, or acetyl octapeptide-3, is an eight-amino-acid peptide that mimics a portion of SNAP-25, a protein involved in neurotransmitter release. Its proposed mechanism in cosmetics is to interfere with the assembly of the SNARE complex, which is crucial for muscle contraction. By modulating this pathway, SNAP-8 aims to reduce facial muscle tension, thereby diminishing the appearance of fine lines and wrinkles. While developer-generated data support its cosmetic potential, direct clinical evidence for muscle relaxation is less robust.
Reported effects
- Reduced appearance of wrinkles
- Smoother skin texture
- Non-invasive anti-aging solution
Reported side effects
- Tolerability generally good in studies
- Potential for skin irritation (with improper formulation or sensitive skin)
- Lack of long-term independent safety data

Important notes
- Dosage refers to concentration in a topical formulation, not an amount for injection.
- The '3% to 10% SNAP-8' on commercial labels typically refers to a dilute supplier solution, not pure peptide concentration.
- Human research often involves multi-active formulations, so SNAP-8's isolated effects are not always clear.
- Formulation stability, pH, and preservation are critical for safety and efficacy.
- This product is for research purposes only and not for human consumption.
Frequently asked questions
What is the typical concentration of active SNAP-8 in a topical product?
Human research and developer guidelines suggest an active SNAP-8 concentration between 0.0015% and 0.005% in the final topical formulation.
If I have a 10 mg vial of SNAP-8, how much cream can I make at a 0.005% concentration?
A 10 mg vial of SNAP-8 can be used to make 200 grams of a topical cream or serum with a 0.005% active peptide concentration.
Does '10% SNAP-8' on a product label mean it contains 10% pure peptide?
No, this is a common misunderstanding. '10% SNAP-8' typically refers to the percentage of a nominal 0.05% supplier solution added to the formula, resulting in approximately 0.005% active peptide in the final product.
Can SNAP-8 be used in a microneedle patch?
Yes, some human studies have evaluated SNAP-8 in dissolving microneedle patches, often in combination with other active ingredients.
