I had a dark sun spot on my cheek for years. I had it treated many times at other offices, and it never went away. It would lighten slightly and then come back just as dark a month later. Mike was more aggressive with my spot and shaved it off with a laser. Once the small scab healed, it was gone for good. Years later, it's still not back. I have gone to him over the past 4 to 5 years for skintyte, DOT therapy, and IPL and have never been disappointed.
