Magnesium Ascorbyl Phosphate

Magnesium Ascorbyl Phosphate is a water-soluble, stabilized derivative of vitamin C that combines L-ascorbic acid with phosphate and magnesium salt. Unlike pure ascorbic acid, MAP remains stable at near-neutral pH (6-7) and doesn't oxidize readily, making it significantly easier to formulate and more suitable for sensitive skin. Formulators choose MAP for its proven ability to brighten skin, stimulate collagen synthesis, and provide antioxidant protection without the irritation and instability challenges associated with L-ascorbic acid, though it requires enzymatic conversion in the skin to become active.
