Mixto c02 fractionated laser treatment
Fractional CO2 laser has different levels superficial, medium and deep and a combination of deep and superficial.
So it depends on what level you are being done and your level of tolerance.
In my practice I add pain meds.
I also Prepare the skin 3 weeks prior to surgery with Obaji skin care with Retin A.
After care is as much importance in getting the optimal results.
For all Laser treatments I always pretreat with the Obagi System (Retin-A and bleaching creams ) for a minimum of 6 weeks and, preferably, 12 weeks. I also usually use, beside what you mentioned, an oral sedative and pain med. I also, personally, do not believe topical numbing is adequate for this. Instead, I use regional blocks to anesthetize the whole area to be treated.
