I had just used up one entire bottle on a few of my old cystic pimples that won't go away. This toner didn't have any effect on my old cysts but did it prevent more pimples? Not really, because new ones did appear on my face. They however didn't become stubborn cysts like the few I have been having on my chest and on my back. It's a decent toner for mild acne problem like what my face has. But for the occasional stubborn cysts resulted from pimples long ago and that refuse to go away, this toner doesn't do a thing to them. I give this a 3 stars out of 5. An 8 oz bottle of this toner is currently sold at $7.47 . Please feel free to disagree with me if you have a totally different experience with this product.
