There are two types of acne on the body: 1. Folliculitis, also known as bacterial folliculitis. Bacterial folliculitis is mainly treated with anti-inflammatory treatment. Anti-inflammatory treatment can be done with topical medications, such as fusidic acid cream, clindamycin gel or mupirocin ointment. If the inflammation is strong, the rash is heavy or there are pustules, oral anti-inflammatory drugs, usually antibiotics, are needed. If you are not allergic to cephalosporins, you can apply cephalosporins or tetracyclines. 2. sebaceous cysts, sebaceous cysts are what the common people call powdery tumors, a cystic subcutaneous growth. It is recommended that surgical excision is relatively complete and not prone to recurrence. However, the prognosis of sebaceous cysts is related to the location, and the recurrence rate after surgery is relatively high in areas of the back that are generally susceptible to pressure. Because the rash is deeper, the cyst wall is not easily removed completely and the risk of recurrence is greater.
