Hello, welcome As you said you are taking steroid which has very common side effect that is steroid induced acne( specially on chest) although treatment would be same as normal acne but you have to stop the steroid have to see other alternative to avoid it. 1. Don’t use hair oil and any sticky cream on face. 2. avoid oily food , chocolate , milk products 3. avoid dust, use sunscreen( above 30 SPF) 4.Any cream don’t rub it on face 5. don t use any steroid creams 6.Continue treatment atleast 1 month 7. Facewash or soaps are not treatment and not much use full 8. Don,t touch acne and avoid pressing it. For treatment Clindamycine ( CLINTOP, FACECLIN, CLEAR GEL) - this is more of preventive and curative so I tell patients to use it all over face in the morning Adapalene gel ( adalene, defferine,)– I tell to use it over acne in the night. Tab doxy 100 mg once in a day.
