What really is needed, is to treat the root of the problem. When I was married, I still had acne bad, and tried many things, including prescriptions that didn't help much at all. While working at a health food store, we had many customers who swore by a simple herbal pill. It was made of dandelion root. I think it might have been called Ac Ne or somthing similar. It costed $11 for a bottle. I figured what the heck, by that time I had spent hudreds on other products. I didn't hold out much faith at all for this product. But by the time I was done the bottle, I was noticing a big difference! Infact, I stopped using it, and havent used it since! What it is is a liver (?) cleanse thing. Instead of trying to stop them from coming on your face, by using things that may really dry out your skin (like I had done) this will treat the root problem.
Best of luck, I know how uncomfortable and embarrasing this problem is!
