Accutane can be purchased, by way of a doctor's prescription, which will definetly to help keep your acne from flaming up. Stay way from the RetinA and other similar products, which have different ingredients than Accutane that can fuck your cycle up. Hell, RetinA has been proven to cause serious depression, even leading to suicide in some rare cases, because of how it greatly affects the chemical composition in the body. This DEFINETLY DOES NOT HELP, especially if you are already bi-polar, or have some other mental "chemical imbalance" in your body...But if the acne is just on your back, don't worry about it. No chick or anyone is going to see it, and if you are worried about ur girl seeing it when you are in the sack, do what the "small dick" guys do...fuck your girl in the dark! LOL
