The best thing for fungus!!!!!! I had a fungus on the nail of my big toe for over two years. I had visited dermatologists and underwent their treatments, but there was absolutely no difference. I searched on my own and based on the reviews I read, I decided to buy this product! Honestly, from the first week, I saw a difference. I didn't expect it. Personally, I applied it in the morning and at night, or only at night before going to bed so it would stay on my nail all night. I frequently filed my nail and cut it until the fungus disappeared. I should add that it had reached halfway through the nail, so it took about 2 and a half months to disappear. The instructions said to continue using the product for another 6 months once the fungus is gone, which I didn't do. Despite that, it has been 2 years and my nail is perfect. If anyone I know has a similar problem, I recommend it and there truly are results.
