While it's debatable if you need anything more than a simple cleanser and washcloth for the face, if you love the idea of an electronic skin brush (created by the makers of Sonicare), then this is the tool for you. It gently exfoliates while it deep cleanses, making it a great product for women who wear a lot of makeup. According to the product Website, the Clarisonic removes 6X more makeup and 2X more dirt and oil than cleansing with your hands alone.
I have tried this skin brush in a spa and liked it a lot. The bristles are very soft, so they are gentle enough for even the most sensitive skin. You can also use your favorite cleansers with the brush.
