Science

Mechanism of Action

Operating as a sophisticated humectant, Hydrolyzed Silk actively attracts and securely binds moisture within the skin's stratum corneum, profoundly enhancing hydration and effectively mitigating dryness. It establishes a protective, breathable film upon the skin's surface, which demonstrably aids in reducing trans-epidermal water loss (TEWL) and forms a shield against environmental stressors. Rich in a diverse profile of amino acids, this ingredient contributes to heightened skin elasticity by promoting collagen synthesis and accelerating cellular metabolism, which in turn diminishes the appearance of fine lines and wrinkles. Furthermore, it exhibits anti-inflammatory and antioxidant properties, serving to calm irritated skin, reduce visible redness, and protect against free radical damage. Hydrolyzed Silk also demonstrates an ability to inhibit tyrosinase activity, contributing to a brighter and more even skin tone.

Stability

Hydrolyzed silk demonstrates stability across a pH range of 4.0 to 8.0, ensuring compatibility with the majority of cosmetic systems. It exhibits good thermal stability; however, care should be exercised to avoid excessive heat during manufacturing to prevent potential denaturation. As a protein-based ingredient, adequate preservation is essential within formulations to inhibit microbial growth.

Conflicts

  • Efficacy may be compromised in formulations utilizing very hard water unless chelating agents are incorporated.
