Age 26, male, will buccal fat removal help me with my midface/nasolabial folds? (Photos)

It's important to understand the impact that different operations can have to your face.

Buccal Fat Removal will reduce volume to the cheeks but will most likely not have an effect on the nasolabial folds. You mentioned you have an underbite, this means that possibly the chin is under-projected and a Chin Implant or a Genioplasty may improve the aesthetic relationship of the lower face to the mid face.

For the deep nasolabial folds, other non-surgical treatments might prove necessary such as Radiofrequency treatments to tighten the skin. In later stages, a Facelift may prove to be most efficacious.
