Azelaic acid
Azelaic acid, also known as azelaic acid, is widely used. In the field of medicine, it is commonly used in the treatment of acne. Because of its antibacterial properties, it can inhibit the growth of Propionibacterium acne, thereby reducing inflammation and effectively improving acne symptoms. At the same time, in the skin care level, azelaic acid helps reduce skin pigmentation. It can inhibit the synthesis of melanin by inhibiting the activity of tyrosinase, which can then achieve the effect of fading pigmentation and brightening skin tone.

Azelaic acid has many benefits. First, it is relatively less irritating than some other acne treatment drugs and is more friendly to people with poor skin tolerance. Secondly, it can not only treat acne, but also improve the appearance of the skin to a certain extent, making the skin smoother and more delicate. Furthermore, long-term use of azelaic acid can maintain a stable state of the skin and reduce the chance of acne recurrence.

However, azelaic acid also has some side effects. Some users may feel slight tingling, itching or redness in the skin when applying it for the first time, which is usually due to a short-term intolerant reaction of the skin to it. If such a situation occurs, the use should be suspended and tried again after the skin recovers, and the frequency of use can be appropriately reduced. In addition, long-term use of azelaic acid may cause dry skin, so it is necessary to pay attention to moisturizing care of the skin during use.

Azelaic acid comes from a variety of sources. In nature, it can be found in some plant and animal metabolites. In industrial production, it is usually obtained by chemical synthesis. Using oleic acid as raw material, through a series of chemical reactions, high-purity azelaic acid can be prepared to meet the needs of the pharmaceutical and cosmetic industries.
