I've had 2 treatments and it's hard to say if it has helped. I'm a little disappointed in the results to tell you the truth. I thought it would help control oil, but it hasn't. I don't usually get deep cyst type spots anymore, but I noticed after each treatment I got 2 or 3 like that. I was planning on getting 4 treatments, but I don't think I will. They are too expensive to not see results.
