I should start here with the bottom line; once you start using it you will never go back to normally washing your face.  I bought this Clarisonic brush because a friend of mine recommended it and it was in all the magazines.  There are a few different sizes with different speed settings ranging from a small travel one with one speed to one with I think three speeds. Additionally, there are different brush heads that range from gentle, normal to ___. The one I have is the original that has two speeds, gentle and normal and I have a normal brush head on it. The directions tell you to use it for one minute, 20 seconds on your forehead, 20 seconds on chin and nose, 10 seconds on each cheek.  It conveniently beeps to let you know when to switch to the next section.  You use this morning and night and switch the brush head out every three months.  Their site says that

I have been using mine since last November and absolutely love it.  My face feels so much cleaner without any makeup or impurities left behind which I noticed ahs helped my breakouts.  My original Clarisonic broke and in the two weeks I went without one I could tell my face was more congested. I can also say that their customer service is amazing!  The button got stuck down and would not pop back up.   I called customer service because they come with a two-year warranty on it and they happily replaced it.  The lady was so wonderful, she apologized for the inconvenience, sent one within two weeks and had a prepaid box for me to send my broken one back in.  These things are pricey ranging from around $150- $200 with the replaceable brush heads running around $25 but I will honestly say it’s a great investment for your skin.  One thing I think it really helps with is clearing the dead skin off that clogs your pores and also allows your products to penetrate better.

Bottom Line: It’s worth the price, invest in the start of your great skincare routine.
