Profound and CO2 at the same time?

Hi I would like to rejunevate my skin and get it tighter with younger looking texture. I have considered fractional co2 laser as well as profound. I have heard that they can be performed together. When this is the case, is the laser co2 used with the same intensity than it is when used alone ? (I've seen that laser co2 can be used with very different intensity and that some practicians even put their patients under general anesthesia to use it full force.) Thank you very much in advance !
