I wish I had before and after photos, my feet are in much better shape after using this. I still need to work on them more but I ran out pretty quickly but my feet were dry af. I used to “shave” my feet once a month this is the power of foot filing in a stick. I will never foot file again. I need to find a way to make it last longer but I think I will not need as much now that my feet are in better shape. Iykyk, get this. It’s greasy as all hell but it’s easy to apply and you can do it over a towel and then put socks on immediately before bed. I wish it was a bigger stick but it is not too pricy so it’s worth it.
