Can I space out CO2 laser treatments by 6 months or a year?

CO2 laser resurfacing of the face can be done to different depths. In general, the deeper the laser goes, the more effective the results. CO2 laser treatments that go deeper also usually involve a longer recovery period though. If I were doing a deep CO2 laser treatment, I normally would only do one treatment. This procedure could be repeated if needed, but I generally wait at least a year before doing it again. My sense is that the laser treatments that you are planning are not very deep and that is why they are recommending 2-3 treatments spaced 6-8 weeks apart. I would not see a problem having your treatments spaced further apart. You should still get improvement even if the treatments are spaced 6-12 months apart.
