I have been reading all the buzz about Clarisonic Cleansing Systems and watching men wander aimlessly around Sephora during holidays looking for them, so I decided to bite the bullet at get one. The original Clarisonic costs $195 and the Mia costs $149. The main difference is the Mia only has one speed and the original has four. The Mia also comes with the sensitive brush head only. You can buy any of the other brush heads for the Mia ( Normal, Delicate, and Deep pore Cleansing). The only one that does not work with it is the body brush head. The single speed and sensitive brush head work fine for me. I do want to try the deep pore head next time.
The main benefit of the Clarisonic cleansing system is the removal of dead skin. When we are younger, the dead skin seems to slough off by itself, but as we age, the skin needs a little help. I use my Mia about once a day, in the shower. I went on vacation for a week and didn't bring it with me and I could definitely see the difference. The prices seem to her very consistent. The only place you might get a better deal is on QVC. They sometimes have special edition versions that come with extra product, like the Clarisonic PLUS bliss Face & Body Collection.
