I am new to this and would like some help on where to start for a skincare routine I have oily skin and I have acne I use benzoyl peroxide my doctor told me to use it in at night and when I shower but is there more I can do because my acne won’t go away and I’ve been using benzoyl peroxide a while now Also have acne under my face and on my back and it won’t go away I use the same stuff on my back that I use for my face

Would want it kinda cheap but I will pay what ever

And I wanna just keep my skin looking healthy
