On the compatibility of vitamin C and azelaic acid
The nourishment of the skin is related to the suitability of various drugs. Vitamin C and azelaic acid are both important agents for skin care, but whether they can be used together is of concern to everyone.

Vitamin C has antioxidant properties, can help the skin resist the damage of free radicals, brighten the complexion, and can also promote the synthesis of collagen. Its liveliness can be effective in many skin care scenarios.

Azelaic acid has inhibitory effects on Propionibacterium acne, can improve acne vulgaris, and can regulate pigment metabolism and reduce pigmentation. Its effects are mild and extensive.

As for whether the two can be compatible, from the perspective of their chemical properties, vitamin C is acidic, and azelaic acid is also acidic. Although both are acidic, vitamin C has strong reducing properties, while azelaic acid has relatively stable chemical properties. When the two meet, there is no chemical reaction in theory, and there is no danger of mutual antagonism.

However, when actually using, you still need to pay attention. Individual skin differences are quite large, and some people have sensitive skin or are intolerant to the combination of the two. Try it on a small area of skin first to see if it has any discomfort, such as redness, tingling, itching, etc. If there is no abnormality, you can gradually expand the scope of use.

Furthermore, the order of use is also exquisite. You can gently cleanse your face first to make your skin clean. Then use vitamin C products, wait for them to be fully absorbed, and then apply azelaic acid. In this way, the efficacy of both may be demonstrated, and the possibility of adverse reactions can be reduced.

In short, vitamin C and azelaic acid may be compatible, but when using it, you should be cautious and take the suitability of the skin as the key to obtain the good effect of skin care.
