Magnesium Aspartate

Magnesium Aspartate Description

The magnesium salt of aspartic acid, an acidic amino acid that plays a role in maintaining proteins in skin. In cosmetics, magnesium aspartate acts as hydrating and softening ingredient. It may be animal-derived or manufactured in a lab (Paula’s Choice uses the latter). Magnesium aspartate is considered safe as used in cosmetics, is non-irritating and bioavailable to skin. Usage levels typically go between 0.5–1%, but lower amounts may be used when the ingredient is part of a blend with other amino acids and glucose-derived ingredients known as gluconates.
