Seems like it's a mixed response for Proactiv. Most people saying it wasn't all that good. There are some proactiv solution reviews that might give you an idea. Only got an average rating so I think you can find something a little better instead.
There are a few different options that can work. Like others said, Proactive is ok. There is a book called acne free in 3 days that is about changing your diet and detoxing. Supposed to work well if you want rid if acne quickly.
