When we look at how blisters form, the best starting point is with the anatomy of the skin. We only see the surface, but skin actually has several layers, the epidermis, dermis, and hypodermis (which is also called subcutaneous). When your skin is subjected to friction from something rubbing against it, the outer layers of skin can separate from inner layers. If this happens, the body responds by filling the space between the separated layers with a fluid called serum.
Serum comes from other body tissues and is used to protect the damaged area while the body works to repair it. As the fluid fills in, a skin bubble forms.
Blisters can develop anywhere on the body, but tend to be most commonly found on feet and hands, since these areas are more frequently subjected to the friction needed to cause a blister.
