We all know the amazing benefits of Vitamin C for achieving radiant, even-toned skin. But if your skin finds it too strong every time you try it, meet its calmer, gentler cousin: Magnesium Ascorbyl Phosphate (MAP).
MAP is a derivative of Vitamin C that is much more stable and gentle on the skin. It has incredible properties that prevent quick oxidation and make it water-soluble, allowing it to blend well with a wider range of skincare products. Another bonus: it is pH-friendly, meaning your skin won’t panic each time you apply it.
While MAP may not work quite as quickly as traditional L-Ascorbic Acid, it is still a powerhouse in its own right. It helps brighten the complexion, reduce the appearance of hyperpigmentation, and provides antioxidant and collagen-supporting benefits. For sensitive skin types or those new to active ingredients, it’s an excellent starting point.
When shopping for products containing MAP, look for moisturizers, serums, or hydrating toners. These are great options for dry, sensitive, or redness-prone skin.
If regular Vitamin C feels too harsh for your skincare lineup, Magnesium Ascorbyl Phosphate might just be the gentle, effective alternative you have been looking for.
Where to find MAP
Magnesium ascorbyl phosphate is the vitamin C in both the Biostem Serum and the Biostem Daily Moisture Complex, so you can use them together for a gentle, stable vitamin C step.
