This stuff is just plain AWESOME! The box says you will have visible results in 3 days, but I had it overnight. Flexitol is similar to Kerasal (which I have used and thought was a so-so product) but works MUCH better. Added benefit- it's about $3 cheaper than Kerasal for twice as much product! I use this in conjunction with the Ped Egg and will NEVER go back to anything else. The directions say to use it twice a day, but I only use it at night and have great results. It only took me about 2 weeks to get my feet in shape and now that I have I only need to use it once or twice a week to maintain it. I also use the Ped Egg a couple of times a month. Before I was having to use it 3-4 times a week to keep the dry, cracked skin off of my feet. One word of caution: When you put this on your feet you need to put on a pair of socks (thin cotton works fine) to keep it off of your sheets and carpets....It will stain!
