Cystoseira Compressa Extract (Cystoseira Compressa Extract)

Cystoseira Compressa Extract is a marine algae–derived botanical ingredient obtained from Cystoseira compressa (brown seaweed) and used in cosmetic formulations for its conditioning, hydrating-support, and protective antioxidant profile. Rich in seaweed-associated polysaccharides, minerals, and polyphenolic compounds (composition can vary with origin and extraction method), it helps promote a smoother, more comfortable skin feel and can contribute to a visibly refreshed, revitalized appearance. The extract is often positioned in “marine,” “anti-pollution,” and “revitalizing” concepts, where it supports moisture retention and helps defend against the look of environmental stress. Common applications include facial serums, creams, masks, after-sun products, and body care, as well as hair and scalp formulas where it can enhance softness and manageability. Use levels and processing conditions are typically guided by supplier specifications to optimize stability, clarity, and sensory performance in the finished product.
