Medication: Patients can be treated with vitamin A acid medication under the guidance of a professional doctor to help unclog pores and dissipate acne. If there is obvious inflammation, anti-inflammatory treatment such as oral clarithromycin and minocycline can be taken; 2. Physical therapy: common ones such as photodynamic therapy and laser therapy can inhibit sebaceous gland secretion, reduce the number of inflammatory lesions and promote tissue repair to varying degrees; 3. Life adjustment: when patients wash, it is advisable to clean the face with a mild oil-control cleanser to reduce oil adherence to the face so as not to clog pores.
