J.O.
I had the same problem many years ago. Your skin is so dry that it's over producing oil and causing pimples. You need to exfoliate really well (avoiding the pimples) and moisturize really well, day and night. Also, use a moisturizing cleanser like CeraVe, which doesn't strip the oil from your skin. Find the richest moisturizer you can and your problem will go away.
