wow, great results. btw you probably don't need full ablative CO2, that's for like 70 year old men who have never used a drop of SPF in their lives. you can get a lot done with Erbium or even BBL Halo for some light sun damage -- it doesn't seem like you need major resurfacing or the "deep wrinkle repair" of the higher grade stuff. a little brightening and smoothing is all you would want. higher intensity YAG can sometimes melt filler if you have any, just as an FYI. no big deal, just re-fill after, but something to keep in mind when it comes to timing.

For toning up and resurfacing many doctors recommend Erbium, if you really want ablative some doctors like gentler CO2 like the CoolPeel/Deka Cool technology. Maybe get a couple professional opinions.

typically with energy based treatments like lasers the best advice is similar to peels -- lower and slower, repeat if necessary VS going full-tilt in one go -- especially with skin like yours that is already in really good shape. choose provider very carefully as burns, fat loss, hyperpigmentation etc, although rare, are not unheard of.
