HIGH ALTITUDE ESSENTIALS TM Magnesium Ascorbyl Phosphate Powder 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 at concentrations as low as 10% to suppress melanin formation (in skin-whitening solutions). It is also important to note that Magnesuim Ascorbyl Phosphate may be better choice than Vitamin C for people with sensitive skin and those wishing to avoid any exfoliating effects since many Vitamin C formulas are highly acidic (and therefore produce exfoliating effects). In skin care products, Magnesium Ascorbyl Phosphate (MAP) is also used for UV protection and repair, collagen production, skin lightening and brightening, and as an anti-inflammatory. It is also a potent antioxidant. It is considered an excellent non-irritating skin whitening agent that inhibits skin cells to produce melanin and lightens age spots, and is a great alternative to Quinone. Magnesium Ascorbyl Phosphate is a also a potent anti-oxidant that can protect skin from oxidation and UV rays, and is used as an anti-inflammatory (Source). Safety Measures/Side Effects: There are no adverse side effects to using Magnesium Ascorbyl Phosphate (MAP), although those with sensitive skin may need to be aware of Vitamin C?s acidic and exfoliating effects. However, Magnesium Ascorbyl Phosphate (MAP) is generally considered more gentle than traditional Vitamin C and therefore safer on sensitive skin. Note: This is a water-soluble ingredient, but it does not dissolve readily in cold water. If you don't have a professional mixer, we suggest that you let the product dissolve over several hours in warm or warm to hot water (40-50C (104-122F), stirring frequently.
