Magnesium Ascorbyl Phosphate (MAP)

INCI Name:
Magnesium Ascorbyl Phosphate

Description:
Magnesium Ascorbyl Phosphate (MAP) is a highly stable, water-soluble derivative of Vitamin C created by combining ascorbic acid with magnesium salt.

Unlike pure Vitamin C, MAP does not degrade easily under heat or light, making it ideal for daily and long-term use in formulations targeting hyperpigmentation, dullness, and aging.
