Fraxel Laser Treatment produces thousands of tiny but deep columns of treatment in your skin, known as microthermal treatment zones. This treatment eliminates old epidermal pigmented cells. It also penetrates deep into the dermis. Just as important, though, are the areas of skin the Fraxel laser leaves untouched. For every microthermal zone the laser targets and treats intensively, it leaves the surrounding tissue unaffected and intact. This “fractional” treatment allows the skin to heal much faster than if the entire area were treated at once, using the body’s natural healing process to create new, healthy tighter tissue to replace skin imperfections.
