Is it better to do botox and fillers before or after CO2 laser?

you can do botox and lasers on the same day, I find that doing the botox prior to co2 is likely going to give you a better result.  Best, Dr. Emer.

My approach for CO2 laser is to pre-treat with Botox so that the skin heals without tension from muscle contractions, then allow 3-6 months for collagen to build.  At that follow-up visit I review Visia scans and then fill in residual areas (lines, creases) with filler.Botox before, filler after.Good luck!

In the big picture is really doesn't matter. The laser will improve the intrinsic quality of the skin and the Botox and fillers work differently. I would recommend doing the CO2 first, then see what else you may need 3-4 months after the laser.Best of luck
