Swelling of lower lids 6 moths after Botox - what is a good treatment option? (photo)

Botox does not usually cause welling. The areas under your eyes look more like fat pads that everyone has, or it may a residual effect of the Botox causing a folding of the skin in a different location.

Botox generally wears off in 3-4 months, however, there are some patients who have prolonged "neuromodulator" (paralyzing) effects for 6+ months. Give it a couple of months then re-assess. My feeling is you will require a filler to camouflage the crease.
Lastly, does the under eye crease only appear with animation (smiling)?

Dear RSProfile,

Very few practitioners inject Botox into the lower eyelids. I would check with your injector and be sure they didn't inject a filler material, which is much more consistent with the complaint that you have. If it was filler, it can be dissolved. Good luck!
