+1 for this. I just used it last month and have some before/during pics if anyone needs.
Some caveats:
If you need your feet to be 100% done peeling for an event or something, plan to use it 3 weeks-a month ahead of time.
Your new skin will be sensitive! Those are protective callouses you're peeling off.
When you use the product, make sure you're settled and able to chill in the same place for a while. Don't be like me with hardwood and tile floors and doggos that need you to get up and do things for them.
If you keep your feet in regular cotton socks, it contains all the dead skin fallout and also helps you peel a little faster.
