PromaCare-MAP is a water-soluble phosphate ester of ascorbic acid that remains stable under heat and light. It undergoes easy enzymatic hydrolysis (phosphatase) in the skin, converting to ascorbic acid and exhibiting physiological and pharmacological activities. Compared to other forms of vitamin C, it is more stable and less prone to oxidation. It effectively boosts collagen production, inhibits melanin synthesis more efficiently, prevents spots, and reduces fine lines and wrinkles.
