Much like many cosmetic procedures, Azzalure  is injected into the skin by a medical, licensed professional. Azzalure is a neurotoxin that gathers the junction between the muscles and nerves and prevents the release of acetylcholine. This is a chemical neurotransmitter which makes the nerves move, allowing movement in the face. Azzalure causes these muscles to relax, preventing the chance of wrinkles and reducing the appearance if there is any there.
