Discussion on whether salicylic acid and azelaic acid can be mixed
Or: "Salicylic acid and azelaic acid can be mixed and used?"

In this regard, various physicians have different opinions. It is said that the two are mixed and can complement each other. Salicylic acid has the ability to dredge pores and exfoliate, which can gradually remove the old stratum corneum on the surface of the skin and make pores smooth. Azelaic acid is not idle either. It can inhibit the secretion of oil, inhibit propionibacterium acne, and improve skin pigmentation. Mixing the two seems to be a good strategy for those with frequent acne, rough skin and uneven pigmentation.

However, some physicians also have concerns. Because salicylic acid is quite acidic, and azelaic acid is also acidic to a certain extent, the combination of the two may cause the skin to be irritated too much. If the skin is already delicate and sensitive, if you mix it rashly, you may appear redness, itching, and desquamation.

Therefore, if you want to mix the two, you should perform a skin test first. Take a little mixture, apply it to the skin behind the ear or on the inside of the forearm, and wait for 24 hours. If there is no abnormality, you can use it cautiously on the face and other skin. And when using it initially, it should be sparse frequently, and when the skin is gradually comfortable, you should increase the frequency. If the skin feels uncomfortable during use, it is recommended to stop using it immediately and seek medical treatment to ensure skin health.

In short, the mixed use of salicylic acid and azelaic acid has advantages and disadvantages. Users should be cautious and weigh the advantages and disadvantages before seeking the effect of skin improvement and avoiding the risk of skin damage.
