It does work. You can’t ever expect a cure from anything, but it’s just a really good regimen and will make your skin a lot clearer, and healthier. I used to use it just to prevent breakouts and had much clearer, healthier looking skin because of it.
I’m not so sure about the comment from ppcakes. I’ve never had a problem with waxing. It may make your skin more sensitive though.
One other thing to consider is going to a dermatologist for a treatment plan, if your insurance will cover it. Acne treatment can be tricky, but they’ve come a long way. Retin-A and other retinoid products seem to be the current gold standard. Other treatments like lasers and peels for chronic acne are also available.
