SARGASSUM FILIPENDULA EXTRACT.

This extract acts as a comprehensive skin protectant through its rich profile of bioactive compounds. It functions as a potent antioxidant, utilizing vitamins, flavonoids, carotenoids, sterols, terpenoids, and polyphenols (including phlorotannins and fucoxanthins) to significantly reduce oxidative stress and combat free radical damage. Its terpenoids confer anti-inflammatory properties, effectively calming skin and reducing redness. Exhibiting antibacterial effects, it can help manage bacterial growth associated with concerns like acne and body odor. Furthermore, it supports anti-aging and skin rejuvenation by replenishing essential nutrients and demonstrating *in vitro* inhibition of collagenase and elastase enzymes, crucial for preserving the skin's extracellular matrix. As a hygroscopic ingredient containing polysaccharides, it also contributes to enhanced skin hydration and a smoother complexion.
