Blepharoplasty corrects excess skin and fat pads on the eyelids. It is really two different operations. On the upper lid, skin is removed, sometimes with a little muscle or fat, to open the eye. On the lower lid, the fat responsible for bags is redistributed or removed, and any skin removal is far more conservative.
What it will not change
It does not lift the eyebrow. A heavy upper lid sometimes comes from a dropped brow, and operating on the lid alone then exaggerates the imbalance. It does not soften crow's feet, which come from muscle contraction and are a recognised indication for botulinum toxin rather than for surgery. It does not change the colour of a dark circle or the quality of the skin. Assessment of the lids and the ocular surface beforehand is essential, because pre-existing dry eye can be made worse.
What recovery looks like
Bruising and swelling of the lids are the rule for the first days and are clearly visible. The upper scar sits in the lid crease; the lower one runs below the lashes or inside the lid depending on technique. Travel guidance suggests waiting seven to ten days after a facial procedure before flying, though the operating surgeon's clearance is what actually governs.
Before you commit
Ask whether the problem is truly in the lid or in the brow, how residual asymmetry would be handled, and who reviews you if eye irritation persists after you get home. Arrange an ophthalmologist you can reach locally before you travel, and get in writing what a revision would cost.
