Cheek implants? Or fillers? (photos)

These options are not mutually exclusive.  Given your youth I would consider starting with a relatively small amount of the appropriate filler and see how you like it. Implants --silicone of polyethylene are often more dramatic, relatively permanent, and symmetric when placed properly. They are still foreign bodies, however that can shift, develop capsules, become infected or cause discomfort.  That is one reason injectable fillers have greatly reduced the number of implants we were used to doing.  Fat is the best and most natural of all the fillers and can be strategically placed for maximum and desired effect, as well as overcome asymmetries, but it is still a surgical procedure and more costly than the off the shelf injectables. 

Cheek implants and fillers were placed in the midface and over the maxilla to create more volume area.  Fillers are performed in the office setting for a temporary augmentation.  Cheek implants are placed through a small incision  through an intraoral approach under brief general anesthesia as an outpatient surgical procedure.  Cheek implants offered a permanent  augmentation.   For more information and many cheek implant before and after results, please see the link and the video below
