The Fraxel is one of several different lasers that we call non ablative fractional lasers. Although there are differences in the way the lasers are operated, they all work by creating "micro thermal zones" (MTZ) in the skin. Each MTZ is shaped like a long skinny pole. The MTZ is an area of skin where the heat from the laser has "cooked" (denatured) the proteins in the skin. These denatured areas cause the rest of the skin around the MTZ to release enzymes to try to repair the MTZ. This repair process causes you to grow new collagen, which gives your skin an improved appearance.
