Fraxel® DUAL 1550/1927 laser treatment targets aging and sun-damaged skin with microscopic laser columns that penetrate deep into your skin to expedite your body's remodeling of collagen. And since the laser treats only a fraction of tissue at a time, it leaves the surrounding tissue intact, which promotes very rapid healing. Fraxel® DUAL 1550/1927 treatment resurfaces your skin by stimulating the growth of new, healthy skin cells from the inside out.
