Science

Mechanism of Action

This ingredient functions through a multi-faceted mechanism of action. The fermentation process meticulously breaks down kelp's complex nutrients, delivering bioavailable forms of vitamins, trace minerals, amino acids, and polysaccharides to the skin. It acts as an efficacious skin conditioner, humectant, and emollient, significantly enhancing hydration and improving overall skin texture. Furthermore, it forms a protective film on the skin's surface and positively influences the dermal microbiome, fostering a balanced environment. Its inherent antioxidant and anti-inflammatory properties contribute to strengthening the skin's resilience against environmental stressors, calming irritation, supporting fundamental cellular functions, and demonstrating potential for stimulating collagen production.
