Blisters

Blisters form when the skin rubs against another surface, causing friction. First, a tear occurs within the upper layers of the skin, forming a space between the layers while leaving the surface intact. Then fluid seeps into the space.

Soles and palms are most commonly affected for several reasons. The hands and feet often rub against shoes, skates, rackets, or other equipment. Blister formation usually requires thick and rather immobile epidermis, as is found in these areas. In addition, blisters form more easily on moist skin than on dry or soaked skin, and warm conditions assist blister formation.
