Science
Mechanism of Action
This synthetic dipeptide operates by signaling the skin to initiate its endogenous repair mechanisms, effectively mimicking the function of natural collagen fragments crucial for tissue regeneration. Its action promotes the reduction of fine lines and wrinkles, simultaneously enhancing overall complexion and skin elasticity. DIPEPTIDE-49 further stimulates cellular renewal by upregulating Ki-67 synthesis and downregulating caspase-9 expression, while also bolstering cellular antioxidant defenses through increased expression of Hsp-90 and inducible NO-synthase.

The Formula
Formulation
Stability
Peptide stability in aqueous solutions is highly dependent on pH and temperature. Degradation pathways typically involve hydrolysis, which is acid-catalyzed at pH 1-3 and also occurs at pH 5-6 near serine residues, and base-catalyzed epimerization at pH levels above 7. Strategic pH optimization and the use of appropriate buffering systems are crucial for maintaining peptide integrity and efficacy in formulations.
