Magnesium Ascorbyl Phosphate (MAP) is a highly stable, water-soluble vitamin C derivative widely used in advanced skincare and personal care formulations. This next-generation antioxidant delivers exceptional brightening and collagen-boosting benefits while overcoming the instability limitations of pure ascorbic acid. As a powerful yet gentle skin-brightening agent, MAP gradually converts to active vitamin C in the skin, providing sustained antioxidant protection and tyrosinase inhibition.
