Laser procedures are a great alternative for clearer, healthier looking nails. Cynosure laser targets the fungus that lives in and under the nail that is responsible for the infection. During the laser procedure itself, you’ll feel a warming sensation and some mild pinpricks as the light penetrates your nails. After the procedure you can return to your regular activities immediately. You can even apply polish to your nails, if you wish (although you must remove any polish before the procedure).
