Do cheek implants move naturally with your facial movements (when smiling, talking) and can people tell if you have them?

Cheek implants and facial movement. No they don’t move which is the same as the bone you have. If properly done by an experienced surgeon you should be very happy. You can always try a filler first. 

Cheek implants are placed on the bone and do not move with facial expression changes. I prefer to place a screw in each implant to secure it to the bone. Cheek implants are permanent and yet, can be easily removed under local anesthesia. If you are tired of getting yearly fillers, cheek implants are a good option.

Yes, cheek implants can give natural looking results and can be customized. However, volume of the cheeks can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra which would allow you to try on the look before committing to a permanent option like implants or fat. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer
