hey yeah so call me wierd, but this is what i have been doing.....i keep a little bit of cornmeal in a cup in my bathroom and i wash my feet using water and cornmeal, it is natural and it makes my feet look smooth and my toenails look really good. It takes a few time of doing it before you notice a difference, but it has been working for me. I actually use it on my face and scalp to as an exfoliator.
Cornmeal is a great exfoliant! Haven't tried it on my feet yet though. I've been using a loofah but my feet seem to be needing some extra help lately..I think I'll give that cornmeal a try. Brown sugar with olive oil is awesome too.
