MAP Reference
Vitamin C is an antioxidant, brightens the skin and reduces fine lines. Vitamin C is unstable in water. Magnesium Ascorbyl Phosphate (MAP) is a water-soluble derivative of Vitamin C. It is the stable form, but it is less potent than direct L-Ascorbic Acid.
L-ascorbic acid is the most potent form of vitamin C, while for dry and sensitive skin, magnesium ascorbyl phosphate, a water-soluble vitamin C, is less irritating.
Vitamin C is widely known for helping to brighten and improve hyperpigmentation, retinol is typically considered best-in-class for wrinkles and fine lines. Retinol is stronger than niacinamide. It’s also known to cause irritation, redness, and dry skin. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol.
