Laser therapy treats toenail fungus infection (onychomycosis), a hard-to-treat infection that changes the appearance and texture of the nail. The laser light penetrates through the nail and soft tissue to both kill fungus in its path, and promotes new nail growth. Once the living fungus is zapped by the laser, healthy nails begin to grow from the cuticle of the nail. This utilizes infrared radiation which is not painful and it is safe to gently heat the base of the nail. Price: $49 Duration: 1 hour
