Function:
Magnesium ascorbyl phosphate is a derivative of vitamin C, is based on vitamin C as raw materials processed with modern science and technology, whether oral or absorbed through the skin into the body, can be quickly digested by phosphatase free vitamin C, Play vitamin C unique physiological and biochemical functions.
Magnesium ascorbyl phosphate has all the benefits of vitamin C. Also overcome the vitamin C fear of light, heat and metal ions, easy to be oxidized shortcomings. Magnesium ascorbyl phosphate is stable in nature and has excellent anti-oxidant quality.
Magnesium ascorbyl phosphate is a water-soluble whitening agent. This product is absorbed through the skin, can effectively resist the invasion of ultraviolet rays, and can capture oxygen free radicals, promote collagen production, can effectively prevent pigmentation, eliminate various skin pigmentation, make the skin moist, white, smooth, and this Stable, non-toxic, non-irritating, as an excellent modern whitening cosmetic additives, the product as a cosmetic additive mainly has the following characteristics:
