Magnesium Ascorbyl Phosphate

Magnesium ascorbyl phosphate

Magnesium-L-ascorbyl-2-phosphate (MAP) is a stable derivative of ascorbic acid. When used as a 10% cream, MAP was shown to suppress melanin formation. A significant lightening effect was seen clinically in 19 of 34 patients with melasma and solar lentigos. Furthermore, MAP has been shown to have a protective effect against skin damage induced by UV-B irradiation. The latter protective effect is because of the conversion of MAP to AS.
