Candela GentleMax Pro is your safest and most convenient option which uses laser heat to weaken and kill nail fungus. The laser beams high-intensity light deep into skin tissue, where it delivers a controlled amount of heat. The upper layers of your skin are protected by the patented Dynamic Cooling Device technology with a burst of cryogen. The Candela Nail Fungus Removal treatment option completely erases toenail fungus, usually eliminating the chance of a regrowth.
