Pore acne is a type of acne, which is a mild form of acne. The main causes of acne are excessive secretion of facial sebaceous glands, abnormal keratinization of sebaceous ducts, blockage or non-passage, and Propionibacterium acnes infection, and acne removal needs to start from these aspects. Topical application of benzoyl peroxide ointment during the day and spot application of erythromycin isotretinoin gel at night. Among them, benzoyl peroxide ointment has the ability to kill Propionibacterium acnes and has the effect of dissolving acne as well as astringent. Erythromycin isotretinoin gel also has the effect of dissolving acne and causing acne to drain. It can be combined with oral tansy ketone capsules, which have an anti-inflammatory and oil-control effect. It usually takes 4-6 weeks of treatment. If the effect is not too satisfactory, you can go to the hospital dermatology department to brush fruit acid or salicylic acid treatment.
