On Azelaic Acid and Adapalene
The disease of the skin is caused by acne. In the treatment of this disease, azelaic acid and adapalene are both commonly used. Compared with the two, each has its own short and long.

Azelaic acid is a natural acid. It comes from grain fermentation and is mild in nature. It can inhibit the growth of Propionibacterium acne, which is one of the causes of acne. And it can reduce the secretion of skin oil. Too much oil often causes clogged pores and acne. It can also adjust the metabolism of keratin, so that the stratum corneum of the skin can be replaced normally, so as not to accumulate and hinder the pores. In addition, azelaic acid has anti-inflammatory effects, which can slow down the inflammatory response of acne and relieve the redness and swelling. It is suitable for mild to moderate acne, less irritation to the skin, and can be tolerated even on sensitive skin.

Adapalene belongs to retinoic acid. Its function is to penetrate deep into the hair follicle, adjust the keratinization of the hair follicle mouth, make the blocked pores unobstructed, and the breeding environment of Propionibacterium acne is no longer restored. It also has significant anti-inflammatory power and can eliminate inflammation caused by acne. It has good effect on moderate to severe acne, can effectively reduce the number of acne and improve the condition of skin lesions. However, it is more intense, and when first used, some people's skin may feel tingling, dryness, and desquamation, and they need to gradually build up tolerance.

If the skin is sensitive and the symptoms are light, it is appropriate to choose azelaic acid. Its mildness can keep the skin stable and relieve acne. If the acne is deep and the inflammation is obvious, adapalene is better. Although there may be discomfort in the early stage, it can be effective if you insist on using it. Both have their own strengths. Doctors should choose them carefully according to the characteristics of the patient's skin and the severity of acne to achieve the best healing effect.
