We appreciate that this is not a Clarisonic 200, reason for which I'm happy with his purchase: it gave me the idea of what is the concept of a device of this kind for less. The usage is easy and, for me, almost daily. I have a hyper sensitive skin so I always use the small ultra soft sponge pink, I found the white hair brush is a little abrasive and I reserve the cleaning once a week. At the point where my skin is more sensitive I make a quick passage, I insist instead on the rest of the face. I also advise not to use soap and / or cleansing gel, but also recommended a cleansing milk, fat and more sensitive he will do well drag your brush on the skin without irritation. I also have another brush such cells but this model I find it much because I can recharge it with the USB cable. So for me (I have a little over a month) is a very good value for money and my skin is much better since I have.
