Last I did it, it recommended not using lotion because it could delay the peeling. Mine took several days to start and quite a few days to finish, but I love the results!It does! My feet are not terrible and it winds up being like if you are peeling after a sun burn. Actually....mine aren't doing anything and I did it Sunday night. If I remember, it takes a bit before it starts peeling. I mostly get it on the bottom of my foot but I use lotion every day on my feet so that may delay the peeling.
