Remove Fungus Effectively with Flash

For a fungus between the toes, it worked fantastically. Looked bad, white and raw with skin peeling. After a few treatments, looks much much better. Skin looks much more normal.

If the fungus is on top of the nail, I can see it working. If it is in the nail bed, it may not work as well since it does not penetrate like that – to my understanding.
