Firstly it comes out of the tube this very strange green colour, but once you start working it onto the skin it turns slightly white and milky. The idea is to lightly scrub the face with this in circular motions for 30 seconds, working on problem areas, then leave it on for up to 2 minutes so it can get to work. After washing off my skin definitely felt a lot smoother, and more even. As far as the brightness of my skin, I didn't notice a huge difference, but that might come over time using it regularly. It's an expensive product, but you really only need about a pea sized amount, if not less. It's great for in the shower, and is an intensive treatment for the skin is just a couple of minutes.
