I have been diligently saving Sephora gift cards for two years in order to buy a Clarisonic skin cleaning brush. In short, I was blessed with lovely, blemish-free skin until I turned 28. Then, like the birthday present no one wants, I woke up one day with awful skin. I have tried everything. I heard from my lovely friend Flamy that the Clarisonic was a must. I'm no physicist, but basically, the brush uses sonic waves (like the Sonicare toothbrush), to jar loose dirt and oil on the skin's surface and in the pores. Sooooo, once I had $200 in Sephora cards, I went down and got my brush this weekend. It works GREAT!!!! My skin was looking better after the first time I used it. It is going to take a while to see really good results, but at least there is hope.
