How Many IU's of Botox Would It Take to Lift the Eyebrows?

Falling brows can result from a combination of factors seen with the passage of time. Firstly, the normal frankfurter-shaped fat pad that sits directly under the outer third of the eyebrows in youth shrinks and shrivels and the little that remains goes South to push the outer third of the brown down over the upper eyelids leading to dermatochalasis or excess skin hanging over the upper lid, like a second lid. . Further contributing to fallen brows is a paradoxical increase with time  in muscular activity of the muscles of facial expression enabling the frown (scowl) muscles and those around the upper eyelids to pull the brows downward. 

In my experience, for the best and most lasting nonsurgical  "Poor Man's" eyebrow lift results  both problems must  be addressed. For the muscular component,  I typically use Botox, approximately 20 units for the frown (glabellar) lines and another four units in each of two locations along the outer portion of each of the eyebrows. (Dyport may also be used for this purpose in does of 50units for the scowl lines and 10 units in each of the two locations of the outer brown mentioned above.) To replace the lost volume and to restore the more youthful,  rounded contours under the outer brows, I typically choose to instill small amounts of Juvederm or Restylane.  The effect can be quite gratifying and the whole procedure may take about ten minutes.

There is unfortunately a lot of confusion in converting Botox dosing to Dysport dosing, but most are using somewhere around 2.5 to 3 so 20 units of Botox equates to 50-60 units of Dysport. For eyebrow shaping, typically I would use at least 15-20 units of Botox so your Dysport dose was on the low side. Give it another try and make sure it has been recently mixed.
