Is It Possible to Get Droopy Eye Lids Right After Botox Wears Off?

Botox should not create any permanent ptosis.  If you had multiple injections over time some of the botox maybe  still present.  You need to let all of the botox wear off which should occur 3-4 months after your most recent injection.  Often patients who develop ptosis or eye lid droop from botox may actually have had preexisting mild ptosis which they compensated for by lifting their brow.  You should have your Dr Assess your eyelids after all botox has worn off.  I suspect you may have preexisting mild ptosis.

The botox that was injected several months ago to your glabella and lateral brow gave you a brow lift.  When botox wears off (usually takes 3-5 months), your skin will return to its starting position.  Botox has no permanent effect. 

But, remember, Botox does not wear off abruptly.  It wears off gradually.  I suspect that the reason why you are noticing more droop on the right is that most of the botox has worn off on the right, but there is some residual botox effect on the left.  Over the next several weeks, the botox on the left side will wear off as well, and your lids will return to the shape that you had prior to any injections. 

The only other thing to consider is whether you have had a stroke.  This can lead to asymmetric facial features.  But given your history and the focality of the defect (R eyelid droop), I think that your symptoms are likely due to the botox wearing off.
