Dr. Marguerite Aitken of Plastic Surgery Associates in Grand Rapids Michigan performed a deep CO2 Laser on my 60 year old sun damaged, ex-smoker, wrinkled face. I'm amazed at the results and truly happy. I feel ten years younger with smooth, soft skin. No pain, just an ouch, ouch, ouch when I rinsed my face after washing it. You wash it 4 to 5 times a day for the first week. I tried filtered water to no relief. I went back to work after two weeks. I highly recommend Dr. Aitken.
