How do blisters “heal”?

221 views

If I ever pop a blister by puncturing the dead skin with something like a needle to let the fluid out, it seems like several hours later, the same dead skin is pocketing fluid again. Why is that? Dead skin shouldn’t be able to heal like that, right? Shouldn’t the hole remain there?

If you pop it like a pin hole, then that hole will be small enough to essentially glue itself shut as the exposed tissue underneath continues weeping and trying to refill.
