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.
