Matrikines: How Peptide Fragments from Collagen Breakdown Signal Dermal Regeneration
Matrikines are peptide fragments released when the extracellular matrix breaks down, and they act as endogenous signals telling fibroblasts to rebuild collagen, elastin, and hyaluronic acid. Topical peptides like Matrixyl and GHK-Cu are essentially exogenous mimics of this repair cascade.
