A peptide formulated for application directly to the skin, often in creams, serums, or patches. Copper peptides (GHK-Cu) and cosmetic peptides (SNAP-8, Matrixyl) are common topical formulations. Skin penetration is limited for most peptides without penetration enhancers.
"Topical Peptide" is filed under Administration in the PeptideAtlas glossary, alongside 15 other terms in that group.
The term applies directly to 1 compound profile here: Snap-8 (evidence F). Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
1 other glossary entry refer to this term in their own definition, which is usually the fastest way to see how it is used in practice.
International Nomenclature of Cosmetic Ingredients — the standardized naming system required on cosmetic product labels worldwide. Relevant for topical peptide products like GHK-Cu (INCI: Copper Tripeptide-1) and Matrixyl (INCI: Palmitoyl Pentapeptide-4).
An injection administered into the fatty tissue layer between the skin and muscle. The most common route for peptide self-administration.
An injection administered directly into a muscle. Some peptides may be administered via IM injection under medical supervision.
Administration directly into a vein. Provides 100% bioavailability but requires medical supervision and sterile technique.
