ELI5: what is happening to your skin when a callus forms?
gpt
Ok, a lot of people are anthropomorphizing the body a little bit with these answers. The body doesn’t “recognize increased pressure/wear.” Actually the pressure itself damages the lipid shells of skin cells causing them to interlock and mesh together more strongly. Then when they die they are more tightly bound to neighboring cells and do not slough off. This process repeated over and over creates a crust of dead skin bound tightly to itself and the living skin underneath. It’s sort of a passive process rather than the active one most people are describing.

Edit: Wow first gold, silver, etc. thanks guys, and also “slough”
