TRIPEPTIDE-34.

TRIPEPTIDE-34 functions as a carrier peptide, initiating the skin's endogenous repair mechanisms. It robustly stimulates the proliferation of dermal fibroblasts and elevates the production of vascular endothelial growth factor. This promotes skin and tissue regeneration, encourages angiogenesis, and accelerates collagen synthesis, all critical for the restoration of healthy skin structure. Tripeptides engage with specific cellular receptors to trigger vital cell migration, proliferation, and differentiation. Specifically, GHK-Cu tightens loose skin, repairs protective skin barrier proteins, and improves firmness, elasticity, and clarity. It effectively reduces the appearance of fine lines and wrinkle depth, smooths rough skin texture, and diminishes photodamage, mottled hyperpigmentation, and skin lesions. Furthermore, it stimulates wound healing, provides protection against UV radiation, and actively reduces inflammation and free radical damage. GHK-Cu modulates metalloproteinase and anti-protease activity, supports regeneration through the synthesis of collagen, glycosaminoglycans, and decorin, and activates the ubiquitin proteasome system (UPS).
