What is the Correct Settings for a Full CO2 Ablative Skin Resurfacing?

Your question did not state which Laser system was utilized in your treatment. There is also no mention specifically of what problem is being treated and the severity of that problem . There is also alot of variability among practioners . Also I did not examine you. For these and for other reasons it is difficult to state if the settings are appropriate. Most importantly were the results good. Has your laser surgeon performed many of these procedures with good - excellent results. These and similar question can give you an indication of your laser surgeon's ability. Good luck!

One thing to consider is that co2 laser resurfacing now a days is based on non continuous type of application of the laser. This cuts down on peripheral damage. For skin, the trt for 20-30 micro meters of skin is 1 milli sec and the optimal fluence is 5 j/m2. 30 w is 30 joules per second with a dwell time of 400 microseconds.  With those settings you might get more treatment of the deeper skin. This could get better results. But I typically stick with the 5 j/m2 and 1 millisecond dwell time for safety reasons.
