Which procedure would help minimize the appearance of a dent under my eye when smiling? (photos)

The dent is likely due to herniation of one of the lower fat pads into an abnormal position. I would advise that you see a Plastic surgeon with an interest in facial aesthetics for full assessment. Treatment may include temporary filler to camouflage the area or surgery to reposition the fat.

Hi there it seems that there is dislocation of the lateral fat pad of the eyelid. This can be corrected with a lower blepharoplasty. It is also possible to camouflage with Botox and fillers , to smooth the area when you smile.

Hello, thank you for your question, we suggest under eye filler
If you want to check the doctor's Instagram page, I added the link, you can take a look and have an idea about the surgery.
