I love these brush heads! They are 100x's better at cleaning your face then using your fingers alone. Really gets deep down into your pores to clear blackheads and leave skin looking youthful and radiant. I don't have sensitive skin, but the Mia 2 I purchased came with several brush replacements all in sensitive . Can definitely be used for normal skin, and works great when paired with Clarisonic Daily face wash. Expensive, but definitely worth every penny. Brush heads need to be replaced every three months, would recommend buying more than one at a time because it can be cheaper than purchasing one every three months. A MUST try, trust me you'll wonder how you ever survived without it!
