I've been using the clarisonic for about a year, and for the first few months (1-4) it was working pretty well. It actually cleared up my skin (along with Murad Acne Complex) about an additional 15%.It made my skin smooth, got rid of dead skin, and worked great as a facial scrub. Then for the next 3 to 4 months I didn't see any more improvement. Afterwards (and up til now) my acne has been getting worse and I have horrible black marks (I can't necessarily call them scars because sometimes they heal and go away after a few months). I used to use it twice a day along with Murad and after the worsening acne I brought it down to once per day, and now I don't use it at all. At first once I stopped I was afraid of getting cystic acne (like I have when I tried to stop using in the past), but thankfully I haven't. I've also been using Murad for about 2 years but have seen no significant improvement in the past year. The first year I saw about a 40% improvement (but as the same with the clarisonic) the past year has done nothing for me. Now I'm thinking about starting on Cetaphil, Black soap, or go back to Proactive (which I last used 6 yrs ago).
Long story short, I would use this product MAX once every other day and only as a scrub or for micro-dermabrasion. DO NOT use this everyday. I've actually spoke with an aesthetician,who said it was too abrasive. Many would say that your skin would have to "purge first", but after 4-6 months of "purging" I personally had to say enough. Please do not use this everyday, it will cause too much irritation and for those with oily skin, it will make the oil increase because your skin is trying to make up for it.
