Science

Mechanism of Action

This ingredient operates by introducing a rich array of fermentation metabolites, including essential vitamins, minerals, protective antioxidants, and beneficial organic acids, resulting from the careful fermentation of kale leaves by Lactobacillus. It actively supports and strengthens the skin's natural barrier through the provision of exogenous lipids, leading to improved hydration and robust defense against inflammation. Additionally, its antimicrobial characteristics aid in rebalancing the skin's microbiome, while its soothing properties reduce redness and irritation, promoting cell renewal for a smoother texture and enhanced protection against environmental stressors.
