I am 56 years old, have had problems with blackheads, acne and oily skin since I was maybe 11 years old. I am not an imaginary "online presence" who is pitching for the company that makes Clarisonic. I actually resent that someone posted that possibility and think it's really ridiculous, that isn't the purpose of this forum. I have had an awesome experience and results with this product, and the Sonicare toothbrush made by the same company and I am sharing this opinion with other people. My results are real and substantial. I don't have really sensitive skin, so I can't speak to that. I use the normal brushhead and have been using the product for over a year. I have reversed gum disease by using the toothbrush for about the last 6 years. Good luck!!
