The medication for acne should be chosen according to the type of acne.1. Type 1 acne, that is, only blackheads or whiteheads, can use topical retinoids. Because acne is related to abnormal ductal keratinization, topical retinoids can maintain normal keratinization, so you can choose topical retinoids at this time.2. Type 2 acne: that is, on top of acne, there is inflammation on the face and the number is relatively small, you can also use topical retinoids. If the inflammation is more obvious, you can choose to use topical retinoids at night and topical antibiotics during the day, such as fusidic acid cream or benzoyl peroxide gel.3. Type 3 or 4 acne: there are nodules and cysts, and the inflammation is very obvious, so you can use antibiotic ointment in the daytime and drugs to maintain normal keratinization in the nighttime, such as retinoids, and you can choose the topical medications of third-generation retinoids such as Adapalene gel, etc.
