Red and swollen pimples commonly have two conditions: acne and folliculitis. If it is acne, you can use topical adapalene gel and retinoic acid cream; if it is folliculitis, you can use fusidic acid cream and mupirocin ointment. 1. Acne: The red, swollen pimples caused by acne are related to factors such as increased follicular greasy secretion of hair follicles and propagation of Propionibacterium acnes. You can use topical medications such as adapalene gel and retinoic acid cream to shrink pores and reduce localized keratinization of hair follicles, thus relieving the symptoms. 2. Folliculitis: Inflammatory reaction caused by infection of hair follicles by external pathogenic bacteria may also cause red and swollen acne. It can be treated with antibiotics such as fusidic acid cream and mupirocin ointment. Red and swollen pimples should first go to the hospital for examination to clarify the cause of the disease, and all medications need to be used under the guidance of a professional doctor.
