Science
Mechanism of Action
This ferment filtrate optimizes skin health through several key actions. It functions as a humectant, effectively drawing moisture into the skin, while its inherent antioxidant properties provide protection against environmental aggressors and oxidative stress. By harmonizing the skin's natural microflora, it helps to mitigate irritation and bolster the skin's intrinsic defense mechanisms. Furthermore, it has been shown to significantly promote procollagen synthesis and decrease pro-inflammatory cytokines such as TNF-α, contributing to improved elasticity, reduced sensitivity, and a brighter, more even skin tone through tyrosinase inhibition.
