Does CO2 Laser Reduce Dark Circles And Retain The Natural Skin Tone?

Hi, I have very dark circles under my eyes and have since childhood. I'm considering using a CO2 laser to remove them. However, someone who works in a plastic surgeons office said that would change the color of the skin under my eyes from the rest of my face, so it might help with the dark circles, but might also result in a funny looking difference in skin tone. Do you know if this is true? I don't want to trade one set of problems in for another. Thank-you.
