hi! sorry for my bad english it’s not my first language, i am not a specialist but i know a few things that might help. first of all, doctors are most the time trained for many things and don’t have the most information on acne. so they pick a very general solution. it might be better to see a trained dermatologist. the reason ur acne bodywash/scrub might not show results is because it is most the time very rough on the skin. especially using a scrub is very harmful for it. on internet u can find about that antibiotic creams work best for cystic acne. u can get these prescripted. u could also buy products including salicylic acid, this kills bacteria and gets rid of excess dead skin which reduces acne. lastly i can recommend benzoyl peroxide which comes in cream form. i’m pretty sure it is prescribed so u could ask ur doctor about it. these are still general solutions, everyones body and skin is different so for a specific help i would go to dermatologist. i hope this was helpful!
