How Can I Recover Faster from Cheek Implants?

Malar and submalar implants can be very rewarding AFTER the initial swelling has subsided. We routinely prepare our patients for 7 to 10 days of recovery before they START recognizing the improvements, but it still will not be the final result. It is this needed patience that makes recovery after cheek implants sometimes challenging.
Otherwise, I have not much to add to the recommendations provided by the other surgeons.
Best wishes for a smooth recovery!

Any operation, including cheek implants is associated with some swelling.  Arnica, Vitamin C, or any of the other numerous chemicals sold for swelling will help.  As healing proceeds at different rates for different individuals, the swelling subsides.

At 1 week post-op, it is normal to have jowl swelling after cheek implants. Aside from ice packs and head elevation, the only other thing that I might add is a short course of methylprednisolone over 6 days. 

I would agree with my colleagues. Manual lymphatic drainage is excellent to reduce facial swelling.
Of course, swelling will be worse in the morning.
Avoid using diuretics. They will have minimal effects on the face and could cause other problems.

It sounds like you are doing everything correctly and it may just take time for the swelling to go away. You can look into lymphatic massage or ultrasound therapy as well which may help the tissues drain faster. Good luck.
