Recurrent acne on both sides of the chin may be related to acne and folliculitis. 1. Acne: It is related to androgen-induced sebum secretion and propagation of Propionibacterium acnes, which can cause a chronic inflammatory reaction in the sebaceous glands of the hair follicles and can lead to recurring acne on both sides of the chin. 2. Folliculitis: due to bacteria and other pathogens infected hair follicles, can lead to local inflammatory reaction, red papules. Commonly found in Staphylococcus aureus infection, can be induced by trauma, decreased immunity and other factors, so it can lead to localized rash recurrence. It is recommended that people with recurring acne on both sides of the chin go to the hospital in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
