White acne, also known as whitehead acne, is a chronic skin disease that occurs in the sebaceous glands of hair follicles. Clinically, it can be treated comprehensively through general treatment, topical medication, oral medication, photodynamic therapy and other methods. 1. General treatment: some whiteheads can recover on their own in a short time, and some of them exist for several weeks or months, during which attention should be paid to keep local skin clean, and warm water and neutral soap can be used to clean the face, so as to minimize the oil adhering to the face and clogging the pores. 2. Topical medications: (1) Vitamin A acids: such as commonly used adapalene gel, tazarotene gel, etc., can play a role in dissolving acne and promote the symptoms of acne discharge. However, mild irritation reaction can occur at the time of initial use, which gradually disappears after adaptation. (2) Benzoyl peroxide: When acne develops to the late stage, it is easy to be infected by bacteria. At this time, benzoyl peroxide cream can be used for treatment, which can kill Propionibacterium acnes through the slow release of the new ecological oxygen and benzoic acid, and also dissolve acne and astringent effect. 3. Oral medication: Oral medication is generally not necessary for mild white acne, but for patients with moderate or severe acne, oral antibiotic medication, such as minocycline, doxycycline, etc., can provide anti-inflammatory and anti-infective effects. 4. Photodynamic: Red and blue light irradiation can be applied appropriately for treatment, which can destroy Propionibacterium acnes and reduce inflammation through photodynamic effect. Therefore, once white acne appears, it is recommended to go to the hospital first, according to the patient’s condition, under the guidance of the doctor for standardized treatment.
