I want to treat my acne, But I have no access to treatments... Options

[synechdoche]

Well, I have moderate acne on my face, back and chest, and I went to the dermatologist for it. She gave me a prescription, which worked for awhile, but then all of a sudden the zits attacked my face again. I asked my mom to take me back, but she told me "We'll go soon... it's just that we have bills to pay..."
My parents aren't willing to go through trillions of different products to see which ones work (I think that they don't think acne's that big of a deal, and with my stubborn skin, I'll probably be going through that many products), and I have no way of getting to a store to buy stuff (no allowance, no job, and I'm too young to drive). I want to treat my acne NOW; I don't want to wait till the next dermatologist appointment (which will probably be in the next year if I'm lucky).

So, I guess what I'm saying is, how can I convince my parents that I want to try to treat this NOW (without nagging them to death/being annoying)?

I think I made sense. I hope I did. :P

Thanks!

Try loreals pure zone. Its like a cheap version of proactiv, but I know people who have used it (myself included) and it has worked wonders for them. Also, if you have bacne (back acne...haha) Try neutrogenas acne wash. These are thing you can pick up from wal*mart for a fraction of the price. And if they dont work, at least make it clear to your parents that you are trying to save them money, and maybe they will cut you a little slack. Oh, and this may sound crazy, but make sure you wash your hair and skin every day. Bacne is sometimes also caused by shampoo and conditioner being left on your back, so make sure you always wash your back after you do your hair. try putting it up in a towel. It helps cuz those products clog pores.
