Why does acne grow on your face in hot weather?

1. Because the human body sweats a lot after the hot weather, the body discharges a lot of waste, which is easy to block pores. Moreover, the frequency of sunscreen cream used in summer is high, and it is easier to grow acne without cleaning.

2. The occurrence of acne is closely related to factors such as excessive sebum secretion, blockage of sebaceous glands in hair follicles, bacterial infection and inflammatory reaction. After entering adolescence, the level of androgen, especially testosterone, rises rapidly, which promotes the development of sebaceous glands and produces a lot of sebum. At the same time, the abnormal keratinization of sebaceous gland ducts in hair follicles causes duct blockage, sebum excretion disorder and keratin plug, that is, micro-acne. Many microorganisms, especially Propionibacterium acnes, proliferate in hair follicles. Lipase produced by Propionibacterium acne decomposes sebum to produce free fatty acids, and at the same time chemotaxis inflammatory cells and mediators, eventually inducing and aggravating inflammatory reactions.

3. When you have acne, wash your face with warm water 1-2 times a day to clean your skin and avoid squeezing or scratching the skin lesions with your hands. Avoid using oil and powder containing glucocorticoid, cosmetics, ointments and creams.
