blister
Sign in to saveA blister is a small pocket of body fluid (lymph, serum, plasma, blood, or pus) within the upper layers of the skin, usually caused by forceful rubbing (friction), burning, freezing, chemical exposure or infection. Most blisters are filled with a clear fluid, either serum or plasma. However, blisters can be filled with blood (known as "blood blisters") or with pus (for instance, if they become infected).
AI overview
A blister is a small pocket of fluid that forms in the upper layers of your skin, typically caused by friction, burns, freezing, chemicals, or infection. While most blisters contain clear fluid, they can also fill with blood or pus, and they matter because they're your skin's protective response to injury that usually heals on its own but may need care if infected.

Smaller blisters are called blebs. The word "blister" entered English in the 14th century. It came from the Middle Dutch and was a modification of the Old French , which meant a leprous nodule—a rise in the skin due to leprosy.
