Acne is generally known as common acne. Acne caused by wearing a mask can be improved by general treatment, medication and physical therapy. 1. General treatment: When wearing a mask, you should reduce the use of cosmetics, choose a refreshing and moisturizing lotion, clean your face in a timely manner, and eat less spicy and stimulating foods as well as foods high in sugar. 2. Medication: Patients with mild to moderate acne vulgaris can apply retinoic acid ointment, adapalene gel, tazarotene gel and other retinoic acid drugs as prescribed by the doctor. When the inflammation is obvious, you can take oral antibiotics under the guidance of the doctor, such as minocycline, doxycycline and so on. 3. Physical therapy: For mild to moderate lesions, physical therapy can be taken, such as red and blue light therapy, which can promote the recession of acne vulgaris and inhibit the inflammatory response. When chin acne occurs, it is recommended that patients go to the hospital and standardize the treatment under the guidance of the doctor.
