Science
Mechanism of Action
This ingredient is meticulously produced by fermenting Yerba Santa (Eriodictyon californicum) leaves with Lactobacillus lactis bacteria. This bioprocess precisely breaks down complex plant biomolecules, isolating specific, beneficial glycoproteins. These glycoproteins actively bind water molecules via hydrogen bonding, thereby optimizing skin hydration at a cellular level. Beyond its primary humectant action, it imparts moisturizing and soothing properties, enhances emolliency for a soft, smooth skin feel, aids in reducing tackiness, and offers robust antioxidant protection against environmental stressors.

Stability
The ingredient maintains optimal stability within a pH range of 5.0-6.5. Some sedimentation may occur upon prolonged standing, necessitating thorough mixing prior to use. Should the product's appearance change due to cold temperatures, gentle warming to 45-50°C followed by mixing will restore its normal state.
