Hello doctor my son is 13 years old and he is having severe acne red bumps on his forehead and on face too. I have consulted skin specialist doctor but for some time its gets improve but later again it's reoccur it. It's now more than 8 months acne still persist the medicine he taken are ketoconazole solution, resorcinol &, sulfur lotion usp. tretinoin cream usp, beclometasone dipropionate & neomycin sulphate, adapalene & clindamycin gel and now is only using betamethasone valerate & neomycin skin on his face. We are unable to understand the real cause of acne whether it's due to fungal or bacterial infection or something other he also now using skin shine fairness soap kindly suggest what we should do to get rid of his pimples.
