I have acne problem especially on my forehead and in between forehead and nose. I also have very oily skin. I visited doctors and applied used some medication as per their suggestion like salicylic acid and glyceric acid face wash and benzoyl peroxide ointment. It worked for sometime but acnes started again even when I continued using those medication. I also did tests for blood sugar which was near border line of having pre diabetes but that has lowered in last 2 months by cutting down on sugar and other suggestions. I also noticed my face became little darker by using these medications and acnes comes up if I stay in sunlight for little longer. Kindly advise what should I do now?
