A few nights ago I figured out a cool way that I like to use my Mia. I like the feeling of it on my skin best when it's hot, so between sections (forehead, each cheek, and nose/chin area) I pause the Mia (just press the power button) and run it under hot water. This not only gets the brush head hot again, but also rinses off any dirt that it may have picked up from the section you just washed so you're not dragging it all over your face.
Clarisonic Mia update
So I've been using my Mia (by the way -- I just got an e-mail today from Clarisonic announcing the release of a LAVENDER MIA! so cute! I wish it was out when I got mine) for about two weeks now, most of the time just at night. After a few days I started to break out a little bit (2-3 blemishes), but I think it was the under-the-skin dirt that was surfacing since the Mia was getting my pores super clean every night, and they had nowhere else to go but up and out of my skin. Yay! Now, two weeks later, I don't have any current break-outs and my skin tone seems to be improving. I have less redness and overall my skin color seems more even. That super squeaky-clean feeling I get after using it is still noticeable to me.
