Crows feet or smile lines occur around the outside of the eye and can extend into the cheek areas. These lines occur when the muscles around the eyes contract in a variety of facial expressions, most noteably smiling.
Treatment For Crows Feet
Small amounts of BTX (Botulinum Toxin A) is injected around the outside of the eye to relax these muscles. Once the contraction of these muscles is reduced the lines which appear as crows feet are significantly reduced.
