Final answer:
A friction blister is the result of repeated rubbing or abrasive forces on the skin causing separation of the epidermis from the dermis.
Step-by-step explanation:
The result of repeated rubbing or abrasive forces on the skin that causes the epidermis to separate from the dermis is commonly called a friction blister. This occurs when there is excessive pressure or friction to the skin, much like the formation of calluses and corns, which are also the result of abrasive pressure on the skin. Unlike bedsores and stretch marks, which are due to excessive pressure and rapid growth, respectively, or eczema and acne, which are long-term skin conditions, a friction blister is an acute response to stress on the skin.
