Magnesium Ascorbate
What is Magnesium Ascorbate?
Magnesium Ascorbate is the magnesium salt of L-ascorbic acid, a synthetic derivative designed for greater stability compared to pure vitamin C. It appears as a white to off-white powder, readily soluble in water, and is incorporated into skincare products such as serums, creams, and toners. In formulations, it primarily serves as an antioxidant by scavenging free radicals and preventing the oxidation of sensitive ingredients like oils and fragrances, which helps extend product shelf life and maintain color integrity. It also works as a skin conditioning agent, promoting skin suppleness by supporting the moisture barrier without greasiness. This form is favored in cosmetics for its milder profile, allowing consistent delivery of vitamin C-like properties across various pH levels and storage conditions.
