Dysport for crows feet.

The crow's feet area does not commonly bruise unless the injections are placed too deep into the surrounding vessels. Compared to other treatment areas, the likelihood of bruising is greatest in this area because the tissue around the eyes is so thin. An experienced injector should reliably avoid those tiny blood vessels, preventing bleeding around or below the eye. An arnica based bruising cream applied to the affected area may shorten the duration of bruising. 

Thanks so much for this question. I suspect this has to do more with your injector/injector technique as opposed to whether it's Dysport vs Botox. You need to follow up with your injector and let them examine you so they understand and help you with your bruising. Best wishes, Dr. ALDO

Bruising does not always occur with an injection of Dysport to crow's feet, but of all the areas that are treated, the eye area is the most likely to bruise because of the thin skin there.  When bruising does occur in the eye area, it normally will gradually move downward to underneath the eye and then gradually resolve.
