Doesn't work on the skin. My toenails had been infected for a very long time. Ridges, discolored, ingrown, and peeling. Didn't know what to do. I just settled for it. Finally mustered up some courage, did some research, and discovered this product. I made sure to file the top of my nails down first before using it. It's been 3 months and my nails are clear enough that it was time to write this review. I applied it once a day, every day. My toenails are clear and normal again. It says to not stop using the product just because everything looks good. It says to keep using it for up to a year to completely kill the fungus and that's exactly what I plan on doing. For the bottom of my feet, I used terbinafine hydrochloride 1%. Cleared everything up in a couple of months so I stopped using it. Everything came right back in a couple more months. So I'm using it again except this time, like the Elon product, I'm going to use it for a year. The product works. Just keep the top of your nails filed down occasionally for better product absorption until your nails are back to normal. Use it daily. Keep using it daily for a year or basically until both bottles are used up. Don't get tempted to stop using it once you see the good results. Follow the instructions. Review: Works on the fungus which nothing else can get rid of! - This stuff really clears up that impossible-to-cure-fungus, that you spend years suffering with because nothing over the counter works. The fungus which causes thick, yellow toenails that crumble away, and scaley, thick, dry skin that flakes off or cracks and bleeds. Like any treatment against this strain of fungus, Elon takes 6+ months, and you HAVE to be consistent, but you will see progress, and after the fungus has visually cleared up, you must continue using it another 3-6 months to ensure every last bit of fungus is irratigated. Also after each shower, the brittlest parts of your affected toenails will be soft and easily dug out and scraped away. Do that before applying this stuff. Doing so makes it easier for the medicine to penetrate down deep where it can be most affective. Forget all the other, cheaper nail fungal medicines and buy this one, it really works! While you're at it, get yourself some tea tree oil balm to use on the skin of your feet. You'll be going bare foot by summer! ## Features - MAXIMUM STRENGTH -- Effectively kills nail fungus by using a unique and natural blend of antifungal agents. Helps to prevent repeated infections with regular and continued use. - HOW TO USE -- Apply the product to clean finger or toenail at the cuticle and under the tip of the nail twice daily.
