Tear trough deformity? Or fat? (Photo)

My recommendation would be lower lid blepharoplasty with fat repositioning. This would involve an incision on the back of the lid (transconjunctival) and taking your natural fat and using it to fill your tear trough. This would remove the “bag” under the eye but also volumize your tear trough. Best to see an eyelid expert.

You have herniated fat in the lower eyelids which can be removed through a trans conjunctival approach with two small incisions made on the inside of the lower lids. Since you're only 27, a conservative amount of fat would be removed.
