Nail fungus often grows under or around the nails. Although these fungi can appear on both the hands and feet, they are more common on the toenails.
The fungus or bacteria often grows under the nail as it uses it to protect itself.
During the session, a licensed professional will apply the laser light directly on your nails and, by going through them, it will effectively kill the fungi that are under them.
The laser also removes any fungus surrounding the nail bed. This procedure is not painful, since it does not damage healthy tissues.
