Back acne is considered to be acne, which can be regulated by general treatment, topical medication, systemic medication and other measures. Back acne is related to the exuberant secretion of androgen in the body, the propagation of Propionibacterium acnes, and the hyperkeratosis of follicular ducts, which will cause the increase of follicular secretion, the accumulation of secretion, and the blockage of acne in the follicular pores, leading to back acne. 1. General treatment: keep the skin of the back clean and hygienic, pay attention to oil control and moisturizing, eat more vegetables, eat less sugary, high-fat food, avoid staying up late and avoiding exertion. 2. Topical medication: Adapalene gel and benzoyl peroxide gel can be used to regulate the secretion of hair follicles and prevent excessive keratinization of hair follicles; antibiotic medication such as fusidic acid cream can effectively control the reproduction of Propionibacterium acnes. 3. Systemic medication: Commonly used drugs include minocycline doxycycline and other antibiotics, but also with isotretinoin, and anti-androgenic drugs, such as spironolactone. It is recommended to go to the hospital for examination first, to clarify the cause of the disease and follow the doctor’s instructions for treatment.
