How to to get rid of acne or reduce it and control redness?

Im 14 and a guy. My face is T oil. Which means my forehead and around my nose gets oily. Im trying to get rid of my acne and acne scars. I drink lots of water, I eat healthy and I moisturize, I use OXY face wash and an anti bacterial cream. But im still getting acne. I’ve searched but they all recommend buying all these moisturizers and creams and all that junk. I want to use something natural, fast and effective. Can anyone help me?
