  2. Corrugator Supercilii muscles. These are the muscles stretching out above the eyebrows marked with the green ticks in the image below. The Corrugator Supercilii muscles cause vertical frown lines.

  3. Depressor Supercilii muscles. These are the muscles on the sides of the Procerus muscle, although some people see these muscles as part of the Procerus muscle.

  • Do not go to sleep or massage the forehead, because this might displace the Botox toward the upper eyelids, leading to a heavy feeling of the eyelid or even a slightly droopy eyelid. Should this happen, Iopidine eyedrops will counteract the effect until it resolves spontaneously in 7-21 days.

  • Slight bruising can occur, but can be concealed with make-up.

  • The effect will kick in after 3-10 days and last between 2 and 7 months, depending on the Botox dosage used and the patients physiology.

  • Some patients dissolve Botox faster than other patients.

  • First time patients will sometimes be requested to return after 2-3 weeks for a check-up and top-up if required.
