Answer 1

So skin is made of lots of layers of cells, and they stick together through stuff that acts like glue. That way, even though you’re doing stuff like sitting on your butt watching Tiger King, or running, your skin doesn’t come flying off.

Foot masks are basically different kinds of acids that dissolve the glue sticking the cells together, so the skin comes off. It takes a while for all of the glue to dissolve, which is why it’s a week of shedding. But, if you do stuff that breaks up the glue naturally (like running or rubbing that skin a lot), it’ll break off earlier.
