I've been using the Clarisonic for about 2 years now, and I still love it. I use it on my face, neck, and chest, twice daily. The fine lines disappeared, and I could feel a difference right away on the texture of my skin. I began using Retin-A about 2 months ago (for acne), however, and found that the change in my skin care necessitated changing to the brush for sensitive skin. Yes, it's pricey; but yes, it's worth it.
