Suggest Treatment For Pimples On The Face,chest And Back

hello :) im 17,sporty-girl, and i have a lot of pimples/pimple marks on my face, chest and back. but the im more concern of those on my face cause it's affecting my self-confidence. i always wash my face under running water after i do sports(after ive cooled down). i've tried a lot of face wash(kept changing after 3-4 bottles yet no improvement) some make it worse and some manage to make my face less oily but did not remove or prevent me from getting pimples. i drink plenty of water everyday but i didn't sleep early. is this the cause of it? i tried to cover it with make up concealer(but wash it once i reached home) but it still obvious under bright lights. i want to know how can i get rid or decrease the pimple marks and pimples break out? do i need a doctor for medication? or dermatologist? will it cost me a lot? can it be cured and can i have smooth, clean and clear skin like others? i need help!
