Magnesium Ascorbyl Phosphate

The details

Magnesium Ascorbyl Phosphate (MAP) is a water-soluble form of Vitamin C. It is used in skincare because it tends to be more formulation friendly than pure vitamin C ( ascorbic acid ). According to research, MAP has three major benefits: While MAP is gentler on the skin than ascorbic acid, it is thought to be less easily absorbed into the skin. In a well-known absorption study, pure vitamin C increased skin vitamin C levels when formulated correctly, but derivatives like MAP did not in that experiment. This suggests MAP may not always convert into active vitamin C in the skin. Due to MAP's stability up to a pH level of 7, it is more stable to air and sunlight exposure than ascorbic acid. The best pH range for MAP is between 5 and 6.
