Should I do under eye fillers before or after a CO2 laser treatment?

I believe the CO2 is a great option for under eyes as well as the filler for loss of volume. It is best to do the CO2 laser, allow for enough healing time (about 1-3 weeks) and then schedule the filler for optimal results. The under eyes are a very delicate area, therefore I highly recommend having a consultation to decide if this is the best treatment plan for you. 

CO2 is the best laser for scars, but Erbium is a great alternative. It may take a series of treatments to see improvements and to maintain. Keep in mind that a tailored combination approach will give you the most improvement with acne scars. I recommend getting a formal evaluation with an experienced cosmetic dermatologist and acne scarring expert. Best, Dr. Emer.
