I have been using the Clarisonic Mia for several months now and I have to say it works quite nicely, but it can also irritate my sensitive skin. It is important to use a very light touch when using this product on rosacea skin. I ended up buying the most gentle brush head clarisonic sells and I am not entirely sure it made a difference. This model has a "regular" speed setting and a "gentle" setting. I honestly don't see much difference between the two, neither setting is particularly abrasive if you don't push too hard against your face. I follow the instructions and use a circular motion, rubbing it against my skin. There is a timer and you are supposed to spend 20 seconds on your forehead, 20 seconds on your nose and chin (because of the rosacea I barely touch my nose and spend most of those 20 seconds on my neck and chin), then 10 seconds on each cheek. The device lets you know when to change areas by pulsing a couple of times. This can be subtle, especially if you are in the shower or distracted in any way, so it is easy to miss. On the whole, I am glad to have this product and recommend it with some reservations.
