I have a few toenails with a bit of a fungus problem so I tried this gel. It does have a thick consistency, so about half of one drop is enough per toenail. I find it was more helpful for me to file down the toenail first. To address, toenail fungus, this will have to be used for at least four months, but the color of the nail improved within two weeks. Here’s hoping that things will improve longer term!
