Gentlemax Pro vs CO2 for clearer skin?

I went to a plastic surgeons office to consult for skin clarity with the gentlemax pro, I was told this would tighten my skin but would not help with mild discoloration and redness? I was told I would need co2 laser to accomplish that. This is the opposite of what I have read when exploring treatment options, the co2 is also 3 times the cost. I am 49 and have very good skin with some light age spots and broken capillaries around the nose. Could someone clarify?
