Sargassum Fulvellum Extract
What is Sargassum Fulvellum Extract?
Sargassum Fulvellum Extract is derived from Sargassum fulvellum, a brown macroalga native to temperate coastal waters of the Northwest Pacific, including regions around Korea and Japan. This seaweed thrives on rocky shores and is rich in marine polysaccharides like fucoidan and alginate, along with phlorotannins, which are unique polyphenols. In cosmetics, it functions as a skin conditioning agent, often incorporated into creams, serums, and masks. It forms a lightweight film on the skin to enhance moisture retention, supports barrier integrity, and offers antioxidant properties to help neutralize free radicals from environmental stressors like UV exposure and pollution. Extraction typically uses water or mild solvents to preserve these bioactive components for topical use.
