Dysport is approved to treat glabellar lines, the vertical wrinkles located in the middle of the forehead, between the eyebrows. They most often start to form during early adulthood and can become more prominent due to decreased elasticity caused by the natural aging process. Glabellar lines can also become more noticeable when squinting, instilling a frowning or angry appearance. Dysport is intended for people who have moderate to severe glabellar lines; patients with mild wrinkles in this area may not qualify for this type of procedure.   In addition to this, Dysport also has medical uses, such as severe muscle spasticity of the limbs in adults and children. Dysport is FDA-approved for use in the treatment of cervical dystonia (a condition that affects neck and head movement), lower limb spasticity in children, and spasticity in adults.
