MAP SL™ (Magnesium ascorbyl phosphate) is a stable, water soluble Vitamin C derivative. Vitamin C has been well-known for its inhibitory effects on melanin formation, but it has not been widely used for this function due to its instability in formulations.
Water Solubility: MAP SL™ is completely water soluble and easily absorbed through the skin. Its water-solubility offers the formulator with formulating flexibility, Stability. MAP SL™ is much more stable to heat and light than vitamin C. Experimental data showed that 3% aqueous solution of MAP SL™ maintained 90% of its activity after 6 months of storage in 40 ºC water bath.
Skin Lightening/Beautifying Effects: MAP SL™ exhibits a strong skin lightening effects which was shown useful in clinical practice. It has strong inhibitory effects on melanin formation therefore resulting in beautified, even-toned skin.
Radical Scavenger: Once absorbed into the skin, MAP SL™ can act as a radical scavenger to eliminate radicals and remove the signs of wrinkles and aging.
Synergistic with Vitamin E: MAP SL™ works synergistically with Vitamin E.
Stable Formulation: Unlike other skin lightening agents such as hydroquinone, MAP SL™ is stable without color change problems.
