Thank you for the photo. I can't tell for sure without an examination but it appears he would need incision technique with some skin removal and possibly the little ptosis correction. This is a surgery under local anesthesia and your sutures will be present for about seven days. It would probably take about 2 to 4 weeks to look natural again. The surgery would look better as the weeks and months go by. Definitely only seek consults and surgical treatment with surgeons who clearly perform Asian eyelid surgery frequently.
