The crow's feet refer to the lines that develop around the sides of the eyes. These are present because of the repetitive action of the orbicularis oculi muscle (zygomaticus major and minor too) which is situated around the eye in a circular shape.
Again one of the most common areas to be treated with botulinum toxin, it can take years off someones appearance.
Injections are placed in the orbicularis oculi muscle in three separate spots either side of the eyes in order to inactivate this muscle and produce the best results.
