Acne generally refers to acne, and recurrent chin acne can be removed through general treatment, medication, and physical therapy. 1. General treatment: For patients with recurrent chin acne, they should choose water or mild cleanser to keep their skin clean and avoid staying up all night. 2. Medication: Topical medications such as benzoyl peroxide, adapalene gel, and retinoic acid cream can be used under doctor’s supervision and are often used to treat mild common acne. If the inflammatory reaction is obvious, you can take oral antibiotic drugs, such as minocycline, doxycycline and so on. 3. Physical therapy: If medication is not effective, physical therapy such as red and blue light irradiation can be used to reduce the number of Propionibacterium acnes and reduce the inflammatory response. If you have recurring acne on the chin, it is recommended that you go to the hospital and receive standardized treatment under the guidance of your doctor.
