"I have struggled with nail for 8 or ten years. All but two toenails were dark. The big toes were thick and tender. I had tried all the home remedies and four bottles of Formula 3 bought from my podiatrist. The Formula 3 was the only thing that gave minimal results. My dermatologist prescribed Kerydin which is working great for me. I was applying twice a day for the first two months. This caused redness and peeling so I cut back to once a day. After four months of use, I can wear sandals again. My left pinky toenail is still thick but will probably heal in time. I'm sorry it isn't working for everyone but keep trying different things. You never know what might work for you. I'm blessed that my insurance covers this or I couldn't afford it."
