Lithothamnion Calcareum Extract (Red Algae Mineral Extract)

Lithothamnion Calcareum Extract is a marine-derived ingredient obtained from calcified red algae (Lithothamnion calcareum) and valued in cosmetic formulations for its mineral-rich conditioning and comforting benefits. Naturally high in calcium, magnesium, and trace minerals (composition varies with origin and processing), it is often used to support a balanced, refreshed skin feel and to enhance the sensorial profile of products positioned for soothing or revitalizing care. In skincare, it can contribute to a smoother appearance and improved comfort, while in hair and scalp formulations it is sometimes included to promote a cleaner, more lightweight feel and support overall manageability. Typical applications include creams, masks, serums, cleansers, body treatments, and scalp products, particularly within “marine,” “detox,” or “remineralizing” concepts. Use level and formulation approach are guided by supplier specifications, with attention to particle characteristics (if dispersed), pH compatibility, stability, and overall system aesthetics.
