Smoking and acne are not directly related. Acne is actually acne. Acne is usually caused by localized keratinization of the follicular sebaceous glands and secondary follicular sebaceous gland infections, such as Propionibacterium acnes infection and Staphylococcus albicans infection. In addition, the patient’s endocrine dysfunction can stimulate the patient’s facial sebaceous glands to secrete a large amount of sebum, and if this sebum accumulates, it is also likely to cause certain triggering infections. In addition, some of the patient’s poor eating habits, including eating spicy and stimulating foods, staying up late, etc., can aggravate the occurrence of acne. However, these are not directly related to smoking.
