SNAP-8 is generally identified in cosmetic ingredient terminology as acetyl octapeptide-3.The name reflects its structure: “acetyl” refers to the attached acetyl group, while “octapeptide” indicates that the peptide contains eight amino acids.
It is sometimes described in consumer products as an “acetyl hexapeptide serum,” but this terminology can lead to confusion with Argireline, which is commonly associated with acetyl hexapeptide-8 and, in some older ingredient references, acetyl hexapeptide-3. Although SNAP-8 and Argireline are both cosmetic peptides often discussed for their wrinkle-related applications, they are different ingredients and should not be considered interchangeable.

SNAP-8, also known as Acetyl Octapeptide-3, is a synthetic eight-amino-acid peptide studied primarily in cosmetic and peptide research. It is structurally inspired by a region of SNAP-25, a protein involved in the SNARE complex and neurotransmitter release.
Research has focused on the peptide’s proposed interaction with SNARE complex assembly in laboratory models. This has made SNAP-8 a subject of interest in in-vitro peptide-formulation studies.
SNAP-8 is related to Argireline (Acetyl Hexapeptide-8), but the two are distinct peptides with different amino-acid sequences. Research involving Argireline should therefore not automatically be interpreted as evidence for SNAP-8.
Published work on SNAP-8 is largely in-vitro and formulation research. Evidence for isolated SNAP-8 remains limited.
Interest in this peptide family is mechanistic: SNARE complex assembly is a defined protein-protein interaction, so short peptides derived from one partner are convenient tools for probing how that assembly is affected in vitro.1
Published work on SNAP-25-derived peptides uses cell-free vesicle-fusion and catecholamine-release assays in permeabilised chromaffin cells, together with in vitro assessment on cultured fibroblast lines.1
This study evaluated a hyaluronic-acid micro-array patch containing acetyl octapeptide-3 along with several other bioactive ingredients. It is cited here as research history only. Because multiple ingredients were present, its results cannot be attributed to SNAP-8, and no outcome is implied for any person.
An Open Label Clinical Trial of a Peptide Treatment Serum and Supporting Regimen Designed to Improve the Appearance of Aging Facial Skin
This was a study of a multi-peptide serum that included acetyl octapeptide-3 among seven peptides. It is cited here as research history only and does not establish the independent activity of SNAP-8, because several ingredients were used together.
A synthetic hexapeptide patterned on the N-terminal end of SNAP-25 was characterised in vitro and reported to interfere with SNARE complex formation in a cell-free system; SNAP-8 is the elongated analogue of that sequence.1

| Lyophilized, in transit | Stable for shipping for up to 3–4 months |
|---|---|
| Lyophilized, short term | Room temperature is usually adequate for several weeks; refrigeration under 4°C (39°F) is generally acceptable |
| Lyophilized, long term | Freezer at -80°C (-112°F) for several months to years |
| After reconstitution | Refrigerated; stable for up to 30 days |
| Light and moisture | Keep cold and away from light in the original sealed vial |
All of our products are manufactured using the lyophilization (freeze drying) process, which keeps them stable for shipping for up to 3–4 months.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until it is reconstituted with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used in the next several days, weeks or months, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
For longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80°C (-112°F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
Once the peptides are reconstituted with bacteriostatic water, they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
