Body acne, especially on the back and buttocks, is very common and highly treatable. Sometimes, breakouts on the arms and buttocks are actually folliculitis (inflamed hair follicles) rather than typical acne. If it is moderate-to-severe acne, oral antibiotics such as doxycycline or minocycline are often prescribed to reduce inflammation and bacterial activity. For severe, resistant cases, oral isotretinoin is a highly effective option. Because these systemic medications require a prescription and proper monitoring, I highly recommend consulting a dermatologist. They can accurately diagnose whether it is acne or folliculitis and prescribe the safest generic medication tailored to your skin.
