Cosmetic Peptides
The peptides you see on labels (GHK-Cu, Matrixyl, Argireline and more), explained one by one, with what each can and can't really do.
Argireline Explained (Acetyl Hexapeptide-8)
Argireline is the brand name for a peptide called Acetyl Hexapeptide-8. A peptide is a tiny piece of protein.
Matrixyl INCI Names: Original, 3000 and Synthe'6 Explained
Matrixyl is a trade name, so ingredient lists show peptide INCI names instead. Original Matrixyl is Palmitoyl Pentapeptide-4.
Peptides and Niacinamide: Can You Use Them Together?
Yes. Peptides and niacinamide get along fine.
GHK-Cu (Copper Peptides) in Skincare
GHK-Cu is a tiny natural peptide (three building blocks: glycine, histidine, lysine) linked to a bit of copper. In skincare it's used as a 'carrier' peptide, sold to help skin look firmer and fine lines look softer.
What Are Cosmetic Peptides?
