The efficacy of Fraxel Restore is limited by the erbium wavelength which brings about much less thermal coagulation compared to Fractional CO2 laser. The advantage of Fraxel Restore is its relatively short downtime of few days and its efficacy to achieve more even skin tone; however even after 5 treatments, the clinical benefits can be very subtle even to professionally trained eyes. If you can afford week-long downtime associated with Fractional CO2 laser and find an experienced board-certified dermatologist or plastic surgeon who has performed greater than 50 cases of your skin type, one single Fractional CO2 Laser treatment can be quite satisfying for rejuvenation, reversal of sun damage, and improvement of skin texture and aging lines.
