My brother has had two (three years apart) and will go for his third in November. It does make a big difference with the overall look of your face and eliminates or diminishes whatever problems are of concern to you. You and whoever will be taking care of you for the first 24-48 hrs have to be braced for what you will look like immediately following the procedure. It's alarming, to say the least, like raw meat, and difficult to think it doesn't hurt but he has told me it doesn't. The deeper the doctor goes with machine the more you will feel some discomfort though. He had acne scaring which caused him to have it done.
