Magnesium Ascorbyl Phosphate is a stable derivative of Vitamin C (ascorbic acid) combined with magnesium. It is an essential water-soluble antioxidant and a potent skin brightening agent.

Due to its stability, Magnesium Ascorbyl Phosphate is widely used in cosmetic formulations to deliver the benefits of Vitamin C to the skin effectively. It helps neutralize free radicals, protect the skin from environmental damage, and stimulate collagen synthesis, promoting a more youthful complexion.

This ingredient is well-tolerated by the skin and suitable for all skin types, making it an ideal choice for skincare products targeting anti-aging, hyperpigmentation, and overall skin health.


Anti-Aging Skincare: Magnesium Ascorbyl Phosphate is used in anti-aging products, such as serums and creams, to reduce the appearance of fine lines, wrinkles, and dark spots, and improve skin elasticity.

Skin Brightening Formulations: The compound is included in products designed to brighten and even out skin tone, resulting in a more radiant complexion.

Sun Care Products: Magnesium Ascorbyl Phosphate is incorporated into sunscreens and after-sun care products to provide antioxidant protection and support skin recovery from sun exposure.
