Fractional laser resurfacing is a laser treatment that treats a fraction of the skin with the laser and leaves the majority of the skin unaffected. Typically about 20-40% of the skin is treated with microthermal zones (MTZ’s) of laser energy. These MTZ’s are columns of tissue heated by the laser that are about 1/10′th the diameter of a hair. By only treating a portion of the skin, the downtime and risks are minimized but the treatment depths can actually be higher – leading to more effective treatments. The Fraxel Re:Store laser is a 1550nm laser wavelength that delivers deeper columns of heat in these MTZs and is known as nonablative laser resurfacing. This means that after a treatment, your skin is pink and puffy and downtime is typically 3 days. The newer Fraxel DUAL laser adds the 1927 wavelength of light that is absorbed at higher levels in the skin and is excellent at targeting pigment issues. Typically, nonablative resurfacing will require multiple treatments, and will have minimal or no downtime. FDA indications for Fraxel laser treatment include treatment of pigmented lesions, acne scars, melasma, mild to moderate periorbital rhytids (wrinkles), surgical scars and actinic keratosis.
