My doctor proposed doing 3 sessions of Youlaser MT on me (CO2+GaAs). He explained that doing regular CO2 was too harsh since my scars aren't deep and that by using this laser I could benefit from both skin tightening and resurfacing. I don't understand why he wants to do 3 sessions over the course of 3 months instead of doing one and only session with a higher setting. I'd prefer having more down time and seeing results faster rather than waiting. It seems like an unusual approach. Thank you
