Yes. You can have CO2 laser resurfacing and Facial Fat grafting, and very often there would be a lot of benefit in performing both of these procedures.
Benefits sought with CO2 Laser Resurfacing:
Rejuvenation of the facial skin with some skin tightening
Improvement of facial wrinkles
Improvement of skin tone, evenness and pore size
Improvement of "sun spots"
Common goals of Facial Fat Grafting:
Rejuvenation and restoration of facial shape and fullness
Providing support below the skin where a thin appearance has developed
Balancing and augmenting for a more harmonious facial appearance
Depending on the specifics of the type of CO2 laser resurfacing and the specific areas being treated with Facial Fat Grafting, there may be circumstances where these procedures can be combined at the same time. Additionally, the "Fractional CO2 laser" has dramatically less downtime than the "older" or "traditional" fully-ablative CO2 laser.
A personal consultation with a surgeon that is experienced in both Fat Grafting and Fractional CO2 Laser resurfacing makes sense to learn about your options.
Hope this helps,
