What options do I have to reduce the appearance of festoons? (photo)

A lower lid blepharoplasty to remove excess skin with a canthopexy to support the lateral canthus would be a good option.

Festoons are certainly one of the more difficult things to treat on the face. In my practice I use three modalities to treat festoons and usually in combination: 1) extended lower lid blepharoplasty to tighten the orbicularis muscle 2) direct festoon excision 3) Laser resurfacing. Best to see an expert in your area.
