I started using the Pro-X Advanced Cleaning System by Olay a year ago. I chose to spend $30 opposed to the Clarisonic for $200. I'm sure the Clarisonic is amazing, but what I don't know won't hurt me.
I love how well it exfoliates and I believe that my skin looks better now than it ever has. Cell renewal is supposed to be one of the benefits. I don't know if that's the case but I get compliments on my skin frequently so something's working! If you are still shopping this is a great gift idea as well...
