My feet are heavily callused from dance in the past. Not in bad shape or ugly really, but I decided to try Satiny Foot Peel Mask. I was skeptical at first until I researched this online. I gave it a try and the hardest part honestly was sitting still with the little plastic sock things on, not moving for a while. I expected my feet to peel on the 4th or 5th day after the initial use, however they started peeling at the beginning of day 3 during yoga class (I know gross, sorry). First it was my toes then the rest of my feet and this went on for a little over a week since I didn't really pick at them. It works- my feet were soft and newer looking. I wish I did take pictures to show process, but forgot. I will buy again in the future when I want to exfoliate.
