It can effectively inhibit the activity of tyrosinase, which plays a key role in the production of melanin, so azelaic acid can significantly reduce the synthesis of melanin, help fade pigmentation and even skin tone. At the same time, azelaic acid also has antibacterial and anti-inflammatory properties, which has inhibitory effects on acne-causing microorganisms such as Propionibacterium acne, which can relieve inflammatory acne and improve skin inflammation.

In the Reddit community, many users shared their personal experience of trying it. Some people say that the combination of glycolic acid and azelaic acid, at first, due to the exfoliation of glycolic acid, the skin feels slightly tingling and redness, but after a few days of adaptation, with the soothing of azelaic acid, the skin tone becomes more uniform, acne is gradually reduced, and the skin texture is greatly improved. Some people also remind that the combination of the two should pay attention to the concentration and frequency of use to prevent excessive irritation. The simultaneous use of high-concentration glycolic acid and azelaic acid may cause adverse reactions such as allergies and peeling in people with poor skin tolerance.
