The hot and humid environment in summer can easily cause sebum secretion to be more vigorous, plus sweating can easily cause bacterial growth leading to the aggravation of acne. Then the patient can be eliminated through general treatment, medication and good sunscreen and other ways. 1. General treatment: first of all, we suggest that patients try to choose cleansing products with good oil control effect, and try to choose skin care products with light texture. Try to eat a light diet, avoid eating greasy sweet food. At the same time, do a good job of sun care. 2. Medication: patients can use topical metronidazole gel, fusidic acid ointment and other antibiotic drugs. For closed mouth acne, you can use topical retinoic acid ointment, adapalene gel and so on. Those with severe inflammation can be treated with oral medication, such as minocycline. For patients with summer acne, it is recommended to go to a regular hospital in time and standardize the treatment under the guidance of a professional doctor.
