Acne, also known as pimples, is a chronic inflammatory disease of the sebaceous glands of hair follicles. It mainly occurs on the face, forehead, back, buttocks and other areas with relatively high sebum production. If acne occurs on the buttocks, it can be treated according to the principles of acne. If the lesions are scattered, few papules, topical fusidic acid ointment or erythromycin isotretinoin ointment can be applied topically. If the lesions are heavy, the inflammatory papules and nodules that appear in this case can be treated with oral tetracyclines, such as doxycycline, tetracycline, minocycline, etc., in combination with topical medications such as fusidic acid. If necessary, physical therapy such as red and blue light irradiation treatment can also be used for treatment.
