Pimples / Acne?

I have some pimples on my face and i think it keeps spreading from one to more and more.. now it covers half of my face. i don't know what happen but i eat apples everyday, avoid poultry, eat many vegetables, wash it with skin care product (cleanser, toner, sun block, currently i stop my moisturiser to avoid over-moist on my face), do mask, keep my room clean and sleep on time. but they still pop up on my face. i've try to go to dermatologist to take out the pimples, but after a week, it comes out again. and when i stop to go there, it keeps spreading on my face. i also drink aloe vera + honey juice to clean my toxic in my body. and i use oxy on my pimples, it only dry my skin with the pimples still at red condition. any solution?
