I let these booties stay on for an hour. They say it takes 7-10 days to peel. My heels started peeling a lot after three days. The new skin is so soft and perfect. My toes and upper part of my feet didn’t start peeling until day 8. It peeled differently then the heels did. Very small dry patches. The only complaint is you can’t use any moisturizer in the time it’s peeling and my feet were so dry and uncomfortable.
