I used to break out almost exclusively on my forehead. It was never-ending and my forehead was absolutely never clear.. One new blemish a day. I've been using this for a little over a month and my forehead hasn't had a blemish in almost three weeks. Thank god.
While this has pretty much stopped my usual breakouts completely, it did not prevent a terrible hormonal breakout on the sides of my face, where I don't usually break out, a day or two before my period. The rest of my face did manage to stay completely clear, which doesn't really ever happen.
Otherwise, I love this product, because I don't have to deal with any burning or stinging and yet it's very good at keeping my pores clean when no other product or prescription worked.
