What are blisters? A blister is a collection of clear fluid trapped between or beneath the top layer of skin, the epidermis. Blisters, which are often called âwater blisters,â often break open and the fluid inside is released onto the skin. Blisters, also known as vesicles, can occur in all age groups and populations.
