Magnesium Ascorbyl Phosphate
Magnesium Ascorbyl Phosphate is a very stable vitamin C derivatives(L-Ascorbic acid mono-didrogen phosphate magnesium salt)which does not degrade in formulas containing water.In skin care products,Magnesium Ascorbyl Phosphate is used for UV protection and repair,collagen production,skin lightening and brightening,and as an anti-inflammatory.It is also a potent antioxidant.It is considered an excellent non-irritating sakin whitening agent that inhibits skin cells to produce melanin and lightens age spots,and is a great alternative to Quinone.Magnesium Ascorbyl Phosphate is a also a potent anti-oxidant that can potect skin from oxidation and UV rays,and is used as an anti-inflammatory(source).It can improve appearance of aged and fragile skin.Widely used as add-on ingredient in skin-lightening products to correct perpigmentation and age spots.Antioxidant effect can be increased by combining Magnesium Ascorbyl Phosphate with L-Ascorbic acid and/or vitamin E.

Vitamin C
Nowdays Various vitamin C derivatives are used in cosmetics for external use . Pure vitamin C, ascorbic acid or also called L-ascorbic acid (ascorbic acid) has the most direct effect.In contrast to the other variants, it does not first have to be converted into the active form. Studies show that vitamin C supports collagen synthesis and fights free radicals. It is also effective against acne and age spots by inhibiting tyrosinase. However, ascorbic acid cannot be processed into a cream because the active ingredient is too susceptible to oxidation and decomposes quickly. Therefore, preparation as a lyophilisate or administration as a powder is expedient.
In the case of a serum containing ascorbic acid, the formulation should have a strictly acidic pH value to ensure the best possible penetration into the skin. The administration should be an airtight dispenser. Vitamin C derivatives that are less skin-active or more tolerable and that remain stable even in cream bases are particularly suitable for sensitive skin or the thin eye area.
It’s well known that a high concentration of an active ingredient does not mean a better care effect. Only the careful selection and the formulation adapted to the active ingredient ensure optimal bioavailability, good skin tolerance, high stability, and the best possible product performance.
