Walking on the soles of your feet is as uncomfortable as stepping on something. It's really annoying to cut the hard skin and grow it back soon!
If there are many corns, it is too much trouble to paste them. You can try this method.
Cut the boiled egg into 4 equal parts and remove the yolk.
Find a bottle, put it in vinegar, and soak the white solidified egg white of the egg in vinegar.
One day later, put the white solidified egg white close to the corns, and then tie it tightly with gauze.
Repeat the next day until the corns fall off.
Vinegar is volatile, so seal the bottle carefully.
Don't walk around after being tied.
You can boil more eggs, and the longer you soak them, the better.
If you feel trouble, you can apply some Youshubizhi cream. It's best to soak in hot water for more than ten minutes before applying, which will be better absorbed.
