Magnesium Ascorbyl Phosphate ( MAP )

MAP is a stable, water-soluble derivative of Vitamin C used in cosmetic formulations for brightening, anti-aging, and skin tone improvement. It is gentler than pure ascorbic acid, making it suitable for sensitive and acne-prone skin. MAP gradually converts to active vitamin C on the skin, delivering long-term benefits without irritation.
