What causes acne in the middle of the body?

Acne may be related to acne, sebaceous cysts and folliculitis.
1. Acne: Due to factors such as high androgen levels, sebaceous glands overproduce and are prone to glandular obstruction, which may lead to acne in the middle of the body.
2. Sebaceous cysts: Localized cysts may be formed when sebum cannot be discharged from the follicles due to the blockage of sebaceous gland ducts in the middle of the body, and accumulates in the glands.
3. Folliculitis: due to bacterial infection of single or multiple hair follicles, can cause local inflammatory reaction, skin redness, swelling, pimples and other symptoms.
It is recommended that people with acne go to the hospital in a timely manner to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
