NOW IM HAVING THEM AGAIN the old pimples are getting read and starting to be a pimple again . I DONT KNOW WHAT GOES WRONG PLEASE HELP ME 
Oily skin usually results in the formation of clogged pores (or closed comedones) like the type of acne you have. They're fleshed-colored bumps, am I right? I have the same issue here. Unfortunately, I do not know how to stop my overactive sebaceous glands from producing oil. However, I do know how to get rid of the clogged pores. I use to have a lot of those closed comedones, and I mean A LOT. I got rid of them using an exfoliant called Mandelic acid. Other exfoliants like salicylic acid and glycolic acid failed me. Maybe you should give it a try? I use a 5% mandelic acid toner. It's pretty sick, I highly recommend!
