Acne Issues

So I have a lot of acne around my chest area and my back and that has basically stoped me from taking off my shirt or wearing something a lil revealing even when I’m around my man. I want to try to get rid of my acne so I’ve been trying to drink more water, shower at morning and night, and eating healthy and all the other stuff ur supposed to do, yet it isn’t going away. If anyone has any type of suggestions on what to do that would be really helpful, thank you.
