What Is The Best Acne Treatment For A 14 Y.o Girl?

I’m 14 and my 2 older brothers and mom had really bad acne that had to be treated by a dermatologist and had prescription for acne cream. I want to prevent that from happening to me so what should I use? I’ve been using Oxy maximum. I have small breakouts, but is there any treatment i could use to make them disappear?
