Easy to use, no problem with application. However, my feet didn't peel in big strips but in millions of little flakes. My feet look horrific and I flake large amounts of dry skin everywhere despite deep scrubbing with brush and pumice every day, even trying to shave the mess down with a blade didn't help. I haven't been able to go without socks for 4 days and counting (without socks every little step leaves flakes behind, gross). To add insult to injury my feet feel no softer and my calluses are no thinner. I'd say my feet were about average before trying this treatment- end of summer season but I take good care of my feet. Maybe I needed thicker calluses or something? Or to leave them on longer than the hour the package said to do?
