Science
Mechanism of Action
As a biomimetic lipopeptide derived from proline, Dipeptide-52 operates by directly stimulating melanocytes within the hair follicle, which are responsible for pigment synthesis. It activates the entire hair pigmentation cascade, from gene expression (including CREB, MITF, and TYRP1) to melanosome transfer, thereby promoting natural hair repigmentation. Concurrently, it functions as a robust antioxidant, safeguarding follicle cells from oxidative damage, restoring redox balance, and ensuring sustained pigmentation. On the skin, it enhances resilience, imparts a soothing effect, and supports hydration in the face of environmental stressors.

The Formula
Formulation
Stability
Dipeptide-52 is typically supplied in a hydroglycerin solution. As with most peptides, maintaining stability requires avoiding extreme pH values. Optimal dissolution is achieved in sterile, oxygen-free water or buffer (e.g., Tris or phosphate at pH 7), potentially aided by sonication and gentle warming, while strictly avoiding excessive heat. Peptides are generally susceptible to degradation via hydrolysis, oxidation, and Maillard reactions, with stability influenced by moisture content, temperature, and pH.
