MarineGlow™ is a natural, marine-derived bioactive ingredient extracted from Porphyridium cruentum, a red microalgae native to the Atlantic Ocean. Under extreme environmental and stress-induced conditions, Porphyridium cruentum secretes sulfated polysaccharides as a defense mechanism. These exopolysaccharides can be cultivated and used in cosmetic applications for instant hydration, enhanced radiance, barrier support, and skin rejuvenation.
