Magnesium Ascorbyl Phosphate (Vitamin C):

Magnesium Ascorbyl Phosphate is a water-soluble, non-irritating, stable derivative of Vitamin C. It has the same potential as vitamin C to boost skin collagen synthesis but is effective in significantly lower concentrations, and can be used to suppress melanin formation. It is a good choice for sensitive skin as well.
