SNAP-8
Topical Reference

The source gives one documented example of formulation math: a 10 mg SNAP-8 vial incorporated into a 200 g batch yields 0.005% w/w (50 ppm) active peptide, using the formula active percent w/w = peptide (mg) ÷ final batch (g) ÷ 10. [2] Preparing a batch like this requires a calibrated analytical balance for accurate measurement; the source frames this as formulation-chemistry context, explicitly not personal dosing advice. [1][2]

Storage: follow the vial supplier's own lot-specific documentation before formulation; the source does not give a single fixed storage temperature for the unformulated vial. [2] Separately, an analytical standard of SNAP-8 remained stable for 96 hours at 4 °C in testing; the source is explicit that this does not equal the shelf life of a finished cosmetic product, and no finished-product shelf life is stated. [2]

SNAP-8 is a synthetic octapeptide (an eight-amino-acid chain) with an acetyl group at the N-terminus, chemically designated acetyl octapeptide-3. [1] It is a topical cosmetic peptide ingredient used in skincare, marketed for anti-aging and wrinkle-reduction applications around the eye area; it is not an FDA-approved pharmaceutical drug and carries no approved therapeutic indication. [1]

The molecular weight and complete amino acid sequence of SNAP-8 are not explicitly stated in the sources reviewed for this page. [1] No peer-reviewed PubMed citation on SNAP-8's cosmetic efficacy, stability, or dermatological safety was available in the sources used to compile this page; the two sources cited below are both from the vial-protocol publisher, not independent journal literature. This page makes no claim of wrinkle reduction or anti-aging efficacy beyond what those two sources state about formulation concentration and study context.

SNAP-8 is not FDA-regulated as a drug, and dosage information for it should be read as topical concentration and study/formulation context, not as a personal cosmetic-use recommendation. [1][2]
