This is so easy to use and the results are amazing! I noticed that it started working within a day and a half. My feet were in really bad shape, very rough and frankly just gross feeling. I wasn't sure that this product would even work for me. After applying the booties and rinsing my feet once time was up, I didn't really notice much of a difference. It wasn't until the next day after soaking my feet in warm water that I noticed that my feet were starting to peel! It took about a week and a few days for all the peeling to stop. My feet use to be rough and just plain gross, now they are smooth and soft. I couldn't recommend this product enough! It's amazing!
