Acne on women’s backs can be due to a variety of reasons such as blocked hair follicles, elevated androgens, and pathogen infections. 1. Hair follicle obstruction: If you don’t pay attention to cleanliness, you can’t remove the oil from your skin in time after it is secreted, which will cause localized hair follicle obstruction and acne. 2. Elevated androgens: If a woman’s androgen level is elevated, it will cause the sebaceous glands to secrete vigorously, thus causing back acne. 3. Pathogen infection: If the patient’s back is infected by bacteria, fungi and other pathogens, it will cause irritation to the skin and cause acne. Women’s back acne may also be related to other factors, when this situation continues to be unable to alleviate, it is recommended to go to the hospital in a timely manner, under the guidance of the doctor for standardized treatment.
