Blackheads, or acne, can be treated with medication, physical therapy, and general measures of conditioning. 1. Medication: When blackheads appear in patients with acne, they belong to class I acne, and patients can use retinoic acid cream as prescribed by the doctor, which has the effect of dissolving keratin and controlling hyperpigmentation after acne inflammation, and can also improve scarring. Patients can also use azelaic acid gel, which can inhibit Propionibacterium acnes and dissolve acne. 2. Physical therapy: Patients suffering from acne can also follow the doctor’s instructions for physical therapy, which can take the form of red and blue light irradiation, chemical peeling treatment. 3. General Measures: Patients with acne should use mild cleansers and should not over-clean the skin to avoid damaging the stratum corneum. Patients should pay attention to sun protection to avoid exposure of the skin to the sun, and should not be forced to squeeze out blackheads. When acne patients have blackheads, it is recommended that they go to the hospital and follow the doctor’s instructions for treatment, and should not use their own medication.
