Blisters are raised areas of collected fluid under the top layer of skin. Blisters are usually circular in shape. The fluid that forms underneath the skin is serum the clear liquid secreted from blood vessels that have been damaged. A blister filled with serum actually acts as a protective buffer for the damaged area.
