Recurrent facial acne should be treated with maintenance therapy rather than stopping the medication as soon as the symptoms improve. Acne is a common inflammatory disease, with the main causes being increased secretion of androgens and sebaceous glands, abnormal keratinization of sebaceous ducts in hair follicles, or proliferation of Propionibacterium acnes, followed by an inflammatory response. Dermatology is the first option for patients with acne, but in some cases, acne can be caused by other primary diseases, of which acne is only one manifestation, so it is important to consider visiting other related departments, such as the gynecology department for polycystic ovary syndrome. Acne treatment is generally divided into topical and systemic medications. Common topical medications include retinoids, benzoyl peroxide, antibiotics, selenium dioxide, and so on. Systemic treatments include oral antibiotics, isotretinoin, anti-androgens or glucocorticoids. In addition, because acne is characterized as chronic and recurrent, it should not be discontinued immediately after the symptoms improve, but should be maintained under the supervision of a physician to prevent or reduce the likelihood of recurrence. Effective maintenance therapy can prevent or minimize the likelihood of recurrence. Therefore, acne patients should follow the doctor’s instructions for treatment and maintenance therapy to avoid delays.
