Acute acne after Dysport every time. Despite what so many doctors say here, it IS directly related. What component causes this?

I am 46, and have had Dysport injections 3x over almost 4 years to try to correct a droopy eyebrow. EVERY TIME I get stubborn acne in the area of the injections starting a week or two after the injections that finally resolves after a few months. I have always had clear skin, never had acne even as a teenager. After a quick search, I see many other ladies complaining of the same thing, yet the doctors all appear to disregard our claims. Maybe it's time to actually investigate the cause?
