Science
Mechanism of Action
This peptide acts as an inhibitor of collagen deformation by mimicking decorin, a key protein that controls collagen aggregation and ensures uniform fibril diameters. By modulating collagen fibrillogenesis, Tripeptide-10 facilitates the formation of thinner, more uniformly organized collagen fibers, thereby improving skin cohesion and elasticity. It functions as a signal peptide, stimulating fibroblasts to increase the production of essential extracellular matrix components including collagen, elastin, fibronectin, glycosaminoglycans, and proteoglycans. Additionally, it offers antioxidant properties to protect against free radical damage and contributes to enhanced skin hydration by aiding moisture retention.

The Formula
Formulation
Stability
Tripeptide-10 is susceptible to enzymatic degradation. Optimal stability is maintained within a pH range of 5.0 to 6.5. Storage should be in a cool (15-25°C), dark environment, with temperatures not exceeding 50°C. In solution, stability is confirmed at -80°C for 6 months and -20°C for 1 month when sealed from moisture. Deamidation, a degradation pathway, significantly increases at alkaline pH, and oxidation accelerates above pH 7.
Conflicts
- Ingredients that induce enzymatic degradation
- Strong alkaline pH environments (above 7)
- High temperatures (exceeding 50°C)
- Combination with other ingredients may necessitate re-evaluation of safety parameters.
Safety
Safety Profile
