| INCI | Magnesium ascorbyl phosphate |
| Manufacture | Magnesium ascorbyl phosphate is produced by direct phosphorylation of ascorbic acid magnesium salt where l-ascorbic acid is suspended in an oxygenated, non-hydroxylic solvent together with magnesium and then treated with a phosphorylating agent. |
| Preservation | Preservative-free |
| Purity Grade | No purity grade applicable |
| Raw Material Source | L-ascorbic acid, magnesium, and phosphoryl chloride (or other phosphorylating agents) |
| Uses | Add at the end of the formulation process just before the preservative, by pre-dissolving in little distilled water. Typical use level 0.2-3%, but up to 10% (for skin-lightening effect). For external use only. |
What is Magnesium Ascorbyl Phosphate, and how does it differ from regular Vitamin C?
Magnesium Ascorbyl Phosphate (MAP) is an esterified derivative of Vitamin C (L-ascorbic acid) that is more stable and less acidic than L-ascorbic acid. Unlike L-ascorbic acid, which is water-soluble and unstable, MAP is both water-soluble and lipophilic, allowing it to be more stable at a neutral pH and easily absorbed through the skin. This makes it a preferred choice for skincare to deliver the benefits of Vitamin C effectively.
What are the primary functions of Magnesium Ascorbyl Phosphate in skincare?
Magnesium Ascorbyl Phosphate serves multiple functions in skincare, including acting as a powerful antioxidant, a skin whitening agent, and a firming agent. It enhances collagen synthesis, protects against photoaging, stabilizes collagen fibers, and inhibits melanin synthesis to lighten and brighten uneven skin tones. It also plays a role in protecting the skin against oxidative stress when used with other antioxidants like Vitamin E.
Is Magnesium Ascorbyl Phosphate suitable for sensitive skin?
Yes, Magnesium Ascorbyl Phosphate is generally considered safe and non-irritating for most skin types, including sensitive skin. Its stability and neutral pH make it less likely to cause irritation compared to other forms of Vitamin C, making it suitable for those with delicate or reactive skin.
Can Magnesium Ascorbyl Phosphate contribute to hair growth?
Recent studies suggest that Magnesium Ascorbyl Phosphate may promote hair growth, especially when used in combination with MSM (Methylsulfonylmethane). This makes it a potential ingredient in hair growth formulations, alongside its established benefits for skincare.
How does Magnesium Ascorbyl Phosphate help with hyperpigmentation?
Magnesium Ascorbyl Phosphate helps reduce hyperpigmentation by inhibiting the enzyme tyrosinase, which is responsible for melanin production. This action makes it an effective lightening and brightening agent for areas of unwanted hyperpigmentation, such as age spots, leading to a more even skin tone.
Can I use Magnesium Ascorbyl Phosphate with other skincare ingredients?
Yes, Magnesium Ascorbyl Phosphate can be used alongside various other skincare ingredients and does not destabilize formulations, unlike some other Vitamin C derivatives. It pairs particularly well with Vitamin E (tocopherols) to enhance antioxidant protection and reduce oxidative stress on the skin.
