The reason why you get acne in the summer is because your sebaceous glands are producing too much sebum or you are sweating too much, which makes your hair follicles clogged. The sebaceous glands produce a lot of sebum in the summer, and too much sebum can clog the hair follicles, leading to folliculitis and frequent acne. In addition, because of the summer sweat more, after sweating is not completely cleaned up may lead to skin bacteria breeding, can also lead to the phenomenon of acne. Avoiding frequent late nights and eating less high-fat, high-sugar foods can reduce sebaceous gland secretion to a certain extent and minimize follicle clogging; in addition, timely and good skin cleansing work to keep the skin clean can also prevent acne. If you need to use medication for summer acne, it is recommended to use medication under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
