Acne

Patient: I have acne on my face that consists of mainly a lot of red bumps with 4-5 big pimples. I have tried several OTC, Proactiv, prescription strength cleansers and lotions. Nothing seems to help. Now I have noticed I am constantly getting them on my inner thighs. The ones on my inner thighs are huge and are painful until they pop and sometimes they do not pop so it takes few days to settle down. What can I do to help prevent these?
