Acetyl Octapeptide-3
Explained
Acetyl Octapeptide-3 is a synthetic peptide also commonly known as SNAP-8. It is a lab-made peptide often marketed as a gentler, topical alternative to Botox.
It works by mimicking part of a protein involved in muscle contractions, which may help relax facial tension and reduce the appearance of fine lines (mostly around the eyes and forehead).
Itâs considered a ânext-genâ version of Argireline (Acetyl Hexapeptide-8), an older peptide with more research behind it that also supports collagen production.
SNAP-8 showed slightly better results than Argireline in one small manufacturer-funded study, but thereâs limited independent research. Plus, most tests use concentrations higher than whatâs typically found in skincare products.
This ingredient might offer a subtle smoothing effect but it won't donât deliver the dramatic results of actual Botox injections.
Think of it more like a supporting actor in your skincare lineup.
