Safe to Have Eyelid Lift 3 Weeks After Botox?

It is a little goofy.  I am a highly experienced eyelid surgeon.  The BOTOX can affect the position of the eyebrow and how the lid fold rests on the eyelid.  This will change as the BOTOX wears off.  To get the most accurate surgical result, you should be assessed when the BOTOX has worn off.  Otherwise it is likely that your surgeon will be adjusting your eyelids to a position that only exists when you have BOTOX in your forehead.

Eyelid surgery should be safe 3 weeks after Botox injection.  Unless your brows were significantly elevated after the Botox injection, blepharoplasty can proceed.  Otherwise, there may be less skin redundancy with elevated brows and once the Botox wears off and the brows come down, you may still have that excess skin to the upper eyelids.  Lower eyelid surgery can proceed if Botox was injected only into the crow's feet. 

To answer this question accurately, I would need to know exactly where the Botox was injected.  Botox injections influence Brow position which in turn will influence the the eyelid skin.  If you are considering eyelid surgery it is best to wait and allow the Botox to wear off before having the surgery.
