How Many Microns Deep or Passes Typically Done with CO2 Laser?

Hello,
If your into "microns" then you are setting your self up for trouble. Device settings do not dictate the actual depth of penetration. The recommended energy settings are from studies that do not always parallel each patients clinical situation. Then there is the doctors experience, healing issues, compliance, etc.
I have used both of these delivery systems and have excellent results. There are treatment "end points" that an experienced doctor knows for each type of clinical setting when using ablative technology. I cannot attest to your doctors experience nor your end result. If I had a patient that was so into the depth/ pass details, I would be concerned as I may have missed the importance of the consultation with you. Take a step back.... Forget about depth..... What are your goals? Can they be obtained?
Regarding the cost, if this is performed in a hospital environment, you have a very good cost but this may not be what will make you happy in the long run.

I used to use the CO2 Silk Touch/Feather Touch ablative laser exclusively with excellent results. However the new Pixel I find gives almost as good results with much faster healing and less risk. Your doctor will know the correct depth for your skin type.
