The dermal regenerator is a hand-held medical instrument that repairs cuts, burns and other skin injuries in moments.
Twenty-fourth-century doctors use the dermal regenerator to close wounds by stimulating the regrowth of skin tissue, passing a small glowing emitter over the injury until it disappears. It is used for minor injuries after combat, accidents or away missions.
Beverly Crusher, Julian Bashir and the Doctor all used regenerators routinely, and the tool reflects a world in which superficial injuries leave no lasting trace. Deeper damage to bones and organs requires other treatments.
