Magnesium Ascorbate is the magnesium salt of ascorbic acid. In skin care it is a water-soluble vitamin C salt, distinct from Sodium Ascorbate, Calcium Ascorbate, and Magnesium Ascorbyl Phosphate. This grade is a white to pale yellow powder that dissolves in water.

Essences and gels continue to specify this INCI when the formula needs vitamin C with magnesium rather than sodium. Cosmetic-grade Magnesium Ascorbate remains a practical bulk active when the assay and the cation are on the COA.
