i have a lot of body acne on my back, chest, arms, and my pubic hair, and i have no medical care at the age 21 also…

I am 15 years old and i have had severe acne since i was 9 years old, i am broke and i have acne scars. Most of my acne has cleared up and has revealed gaping scars on the side of my cheeks. Is there any way that i can get rid of them before prom next may on no money???

In fashion and advertisements, I know they edit photos to remove acne, make women look slimmer, etc., but I’ve heard that it costs more the more you have to edit. I don’t get it. Shouldn’t it cost the same to edit a small part of a photo, than many parts? What more are you paying for, once you’ve got the editing program and the person to use it?

I’ve had acne for a few years now and i think its all gone. now i just have these scars from picking at them. are there any home remedies or cheap products i can buy to get rid of them and wont dry out or make my skin really oily??
