What should i have for my skincare routine?

Ok i have combination skin and i dont wanna waste a lot of money on products. So please only suggest products from the drugstore because i dont have a sephora or stores like that near me. I have keratosis pilaris on my cheeks and i sometimes get 1 or 2 pimples on my nose forehead or nose. I also have keratosis pilaris on my upper arm and i have some on forearm and i REALLY want to get rid of that now!!! And my parents DO NOT want to take me to the dermatologist not even if i beg them 100 times or get somebody else to tell them!!! So dont tell me to go to the dermatologist.... because thats going to get me annoyed..So all im asking is if you guys can suggest some things for my skincare routine that is from the drugstore and i need the things to be like organic or for it not to have a lot of harmful chemicals that will f**k up my face and arms ( i am new to the skin care thing so i need everything) So i need a skincare routine for my face and arms please! :) THANKS!
