For the device intended to permanently remove one hair at a time, see Electric tweezers. Closeup of the head of an epilator. An epilator is an electrical device used to remove hair by mechanically grasping multiple hairs simultaneously and pulling them out. The way in which epilators pull out hair is similar to waxing, although unlike waxing, they do not remove cells from the epithelium of the epidermis. Aside from the spring in early spring-type epilators, there are no parts in epilators that require regular replacement.
Epinephrine is a chemical that narrows blood vessels and opens airways in the lungs. These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and other symptoms of an allergic reaction. Epinephrine injection is used to treat severe allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs, and other allergens. Epinephrine is also used to treat exercise-induced anaphylaxis.
