Peptides

Also listed as: palmitoyl tripeptide-1, palmitoyl tetrapeptide-7, matrixyl, signal peptides, oligopeptide

Signal peptides support collagen and layer fine with exfoliating acids and retinoids (the GHK-Cu copper peptide is the one exception - apply it first, then wait before an acid step).

Retinoids and peptides nudge the skin to firm up and soften the look of fine lines with regular use.
