Would half a syringe per cheek give me noticeable results? (Photos)

The cheek is a broad area. It sounds like a lot to get more than one syringe split between two cheeks, however 1 cc is 1/5 of a teaspoon. So if you use that for both cheeks that means 1/10 per cheek. There will be a small visible difference, but not significant. To really make a difference most patients need at least one syringe (one cc) per cheek. 

One syringe of voluma will produce an aesthetic improvement that will produce a subtle, but measurable result.  If you are only going to have one syringe injected in your cheeks, use Voluma because other fillers do not have the same lifting capability.  Since this is completely elective and you already have nice volume in your cheeks, the other option is to use that money on your vacation.  Good luck!

This will give you subtle improvement. Symmetry and volume of the cheeks can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra. Implants or fat are alternatives. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer
