Why Does Your Skin Need Stable Vitamin C?

Understanding Stable Vitamin C

Stable vitamin C is a form of vitamin C that does not become easily oxidized by air or light, or heating. 

Typical stable derivatives are:

  • Sodium Ascorbyl Phosphate -Safe and potent for acne-prone skin.
  • Magnesium Ascorbyl Phosphate - Hydrating and non-irritating.
