Science

Mechanism of Action

This extract functions as a potent humectant, efficiently drawing and retaining moisture within the skin. It supports the skin's natural barrier by depositing sulphated phycocolloids onto skin proteins and enhances the natural moisturizing factor (NMF) through osmoregulating molecules. Abundant in antioxidants like fucoidan, laminarin, and polyphenols, it actively neutralizes free radicals and mitigates environmental damage. Furthermore, it exhibits anti-inflammatory effects that soothe irritation and reduce redness, contributes to a brighter complexion by addressing hyperpigmentation, and promotes improved skin firmness, elasticity, and cellular regeneration.
