Magnesium Ascorbyl Phosphate
What is Magnesium Ascorbyl Phosphate?
Magnesium Ascorbyl Phosphate is a water-soluble ester derivative of L-ascorbic acid, formed by attaching a phosphate group and stabilizing with magnesium ions. This chemical modification boosts its stability against oxidation, light, and heat compared to pure ascorbic acid. Primarily used in leave-on skincare products like serums, creams, and toners within the antioxidants and skin conditioning categories. It functions by gradually breaking down in the skin's moist environment to release active vitamin C, which neutralizes free radicals and supports cellular protection. Its neutral pH makes it compatible with a wide range of formulations, enhancing shelf life of sensitive ingredients while providing gentle delivery for daily use without common stability issues of traditional vitamin C.
