Slow Healing from Lower Blepharoplasty? (photo)

This may be tender fat obstruction which should subside within 6 months. Gentle massage to the area should help the swelling.

Thanks for the posted photo. Yes gentle massage is slowly helpful. In my opinion a lateral canthopexy is needed with a filler in the tear trough. 

We Cosmetic Surgeons could suggest many different ideas to help you: But TIME, massage, cool compresses, allergy control, future fillers and possibly lower eyelid tightening surgery may be beneficial.
