SNAP-8

In plain terms

SNAP-8 is an eight-amino-acid peptide, a shortened form of a longer sequence studied in skin research. Laboratory work has looked at how it interacts with the proteins involved in muscle-cell signalling in skin tissue models. Research is in cell cultures and laboratory skin models.

Research overview

SNAP-8 is an eight-amino-acid peptide, a lengthened form of the sequence studied for how it interacts with SNARE proteins in skin tissue. Research is carried out in cell cultures and reconstructed skin models, and much of the published work concerns formulation — how well it penetrates and how stable it stays in a topical preparation.

What has been studied

1. 1

   Muscle-cell signalling in skin

   SNAP-8 is a shortened form of a longer peptide studied for how it interacts with SNARE proteins, which are part of how nerve signals reach muscle cells in skin tissue.

2. 2

   Laboratory skin models

   Research has been carried out in cell cultures and reconstructed skin models rather than in living subjects.

3. 3

   Topical formulation research

   Much of the published work concerns how well it penetrates and remains stable in a topical preparation.

Direct published research on acetyl octapeptide-3 (SNAP-8) itself is limited. The work cited here concerns the closely related acetyl hexapeptide-8 and the wider use of synthetic peptides in cosmetic formulation, and is listed for context rather than as research on this exact compound.
