Before my Nutra Sonic I would clean my face with soap and a facial scrub and use toner afterwards only to find my face wasn't as clean as it should have been. I have very sensitive, T-zone skin and need to be careful about what I use on my face but I thought I would take a chance Nutra Sonic and I'm glad I did. The first time I used it, I started with the brush for sensitive skin for about a minute or so on a Friday night before I went to bed just in case I experienced any adverse affects. Not only was my face glowing but it was clean! After a month I noticed my periodic breakouts reduce in magnitude and on some months disappear altogether. I still use Nutra Sonic every night (and in the mornings in the summer) with the brush for normal skin but it's been over a year and I am still very happy with this product!
