Cartalax vs Palmitoyl Pentapeptide-4

Tetrapeptide bioregulator from cartilage tissue; stimulates chondrocyte proliferation and extracellular matrix synthesis; normalizes gene expression in cartilage cells

A Khavinson peptide bioregulator targeting cartilage tissue. Promotes chondrocyte activity and cartilage matrix regeneration; studied for osteoarthritis and joint degeneration.

Binds TGF-β receptors on fibroblasts, upregulating collagen I, III, fibronectin, and hyaluronic acid synthesis. The palmitoyl chain provides lipophilicity for improved skin penetration into the dermis.

A lipopeptide consisting of a palmitoyl fatty acid attached to the pentapeptide KTTKS. A key component of Matrixyl 3000 formulations. Stimulates collagen and extracellular matrix production more potently than palmitoyl tripeptide-1 (Matrixyl) alone, particularly for deep wrinkle reduction.
