How long does Dysport last? (Photos)

Dysport typically lasts about 3-4 months. 21 units between the eyes is not too much if it's dysport units. It may be difficult to hold your eyes open in sunlight as the muscles that you use to squint/reduce brightness are now paralyzed due to the Dysport. As for the wrinkles underneath the eyes, that can sometimes become more prominent after treatment of the crow's feet due to compensatory hyperactivity. In other words, because one part of the muscle is selectively paralyzed, the other parts will work/contract harder which is likely the cause of the new under eye lines. Once the product wears off, your facial expressions should return back to baseline.Hope this helps!

Generally speaking, Dysport lasts 3 to 4 months. For your eye condition, I suggest you see an eye specialist about the potential dryness of your eyes.Best wishes, Dr. ALDO :)

I'm sorry you are unhappy with your Dysport results.  In general the treatment will wear off gradually over about 3 months.  The amount you stated you received in the glabella area is much lower than typical.  I recommend returning to your injector for an evaluation and discussion of your concerns.
