Science
Mechanism of Action
This extract, abundant in zinc carbonate, actively stimulates collagen synthesis, thereby enhancing skin elasticity. It functions as a potent antioxidant, neutralizing free radicals to mitigate oxidative stress and signs of premature aging. Furthermore, Smithsonite Extract aids the skin's innate repair mechanisms, promoting regeneration and healing, and demonstrates anti-inflammatory properties to soothe stressed or irritated skin. Its benefits extend to improving hydration, regulating sebum production, and contributing to a more even skin tone by reducing hyperpigmentation.

Key findings
- 01 Clinical application within a cosmetic composition demonstrated that Smithsonite extract, used between 0.0001% and 10.0% by weight, effectively protects skin from external irritation and provides significant moisturizing benefits. Optimal efficacy was observed at concentrations ranging from 0.001% to 5.0%. Concentrations below 0.0001% showed diminished protective effects, while those exceeding 10% risked compromising formulation stability and aesthetic feel.

Stability
Smithsonite Extract maintains stability across a broad range of cosmetic formulations under normal conditions. It is dispersible in most formulations despite being insoluble in water. The ideal pH for formulations containing this ingredient is approximately 6.0 to 7.5 (for a 10% solution). Formulators should avoid strong acids and alkalis.
Conflicts
- strong acids
- strong alkalis
- potential for phase separation, unexpected changes in color, texture, or odor, sediment formation, precipitation, or oxidation if incompatible with other ingredients.
