I would strongly suggest you avoid CO2 lasers. They created large zones of heat induced coagulative damag and thus result in long recovery and prolonged redness. Erbium beams can cause ablation so fast that there is no measurable coagulative heat damage, this means less redness and recovery. A fractional CO2 laser like fraxel or DEKA's SMARTXide have never made sense to me. If you fractionate the beam you still get widespread coagulative damage of the entire treated area thus there is really no advantage to the fractionated beam. I use only Erbium lasers for deep resurfacing. The Profractional XC laser by Sciton is the world leader. It allows me to adjust exact treated depth and percentage of surface treated so I can deliver a three day recovery or a one week recovery depending on patient needs and expectations. Fractionated beams that cannot separate coagulative and ablative energy are marketing ploys in my opinion. I have never treated a patient with Fraxel or DEKA SmartXide( I have used both) with significant energy that wasnt red and swollen for weeks. Sure you can turn down the energy and get quicker recovery, but a tthe sacrifice of results. If you want fractional laser results, look beyond CO2. I hope this helps,
