CO2 laser energy removes the outer layers of skin so that new, fresh, tighter skin can grow in to replace the wrinkled and discolored skin. The laser energy cannot penetrate through all of the layers of the skin and affect the underlying fat. It is very common in my practice for patients to have CO2 laser resurfacing to address the fine lines, wrinkles, and discoloration, and also during the same procedure undergo fat transfer to replenish volume because the majority of women need both issues addressed. If there is a perception that CO2 laser has diminished facial fat volume, it is likely that both procedures were needed and it is now more apparent that there is a lack of volume.
