Soak your feet!
Works well! I had thick calluses.  The first time i used it worked well, but I wanted better results.  I waited two weeks and went through the process differently. I soaked my feet for 30 min before using then soaked every say for about 20 minutes.  The peeling works faster and I had better results the second time. It could be because I already did it once or because of the soaking. I recommend soaking prior and every day for best results!
