The fractional CO2 Lasers (Fraxel re:Pair, ProFractional, Fractional FX, Deep FX, etc) are all quite effective for treating wrinkles, acne scars, enlarged pores, etc. In a recent article in the Plastic and Reconstructive Surgery Journal entitled "Fractional Photothermolysis for Skin Rejuvenation" (Cohen, Henssler, Johnson) - the Conclusion was : "Fractional photothermolysis represents a breakthrough in laser treatment for a wide array of skin problems." The study did compare non-ablative and ablative (fractional lasers) . It also concluded that "The Re:pair delivers the deepest injury of any of the nonablative and ablative fractional lasers." and "The delivery system is thought to be faster than any other device on the market and ... it provides a very versatile range of fractionally ablative treatments." "The handpiece...provides optimal, uniform delivery of energy for greater safety, speed, and efficacy. Early clinical results have been impressive." This basically means the laser treatment can be tailored to your particular problems and severity of skin damage. So be sure to ask your physician, whether a board certified plastic surgeon, facial plastic surgeon or dermatologist, what their experience is with the various lasers, why they prefer what they use, what are their results, how many treatments does it take, can you see photos or even talk with patients that have had this procedure. All of this will help to build a level of confidence in your physician.
