At first I thought it's quite expensive, but since my pimples are really bothering these days, I decided to give it a try. It really works very well. The big pimples with whiteheads actually shrank the next day and gradually flattened in a couple of days. The scar also disappeared very quickly.In fact I was so impressed that the next day I went back to buy their blemish hydrator which helps to speed up the recovery. I also bought a concealer to help hide the scars while they are being cured.
