Nope, Nothing, waste of money
I bought this product to soften and remove rough callouses on my feet. Was so excited to try it that I bought a 4pk. Well,  I'm sad to say that it did not work for me at all beyond a burning sensation and  some mild (as in barely any) flaking 3 days later.  I followed the directions to a "T" and kept the booties on for the maximum time as recommended.  I'm really bummed and sad I wasted my money.
