Acne is generally referred to as acne, and small acne particles on the face need to be treated by topical or oral medication on the basis of changing lifestyle habits. 1. Changing lifestyle habits: Acne patients should wash their face with warm water 1~2 times a day to avoid clogging pores with oil and avoid squeezing or scratching the lesions with their hands, in addition, they should avoid excessive intake of high-sugar and high-fat foods to avoid aggravating the condition. 2. Topical medication: patients can follow the doctor’s instructions to apply topical tazarotene, adapalene and other vitamin A acid preparations, but also use benzoyl peroxide, clindamycin, erythromycin and other drugs to kill Propionibacterium acnes. 3. Oral medication: If moderate or severe acne develops, oral antibiotics, such as minocycline and doxycycline, can be taken to control the condition, in addition, oral isotretinoin can be taken for severe acne. If accompanied by the manifestation of high androgen levels or polycystic ovary syndrome patients, oral compound cyproterone acetate can also be taken. Regardless of which treatment method is used, maintenance treatment should be continued after the lesions have subsided, and patients are advised to seek timely medical attention and standardize the use of medication as prescribed by the doctor.
