Hi Jerronba,I think 4ml of Voluma per cheek may be too much, but you will know as you are having it injected.The best part of fillers is that it is WYSIWYG, or What you see is what you get. The fillers are opened one at a time, so as you finish 1-2 syringes on the first cheek, you will have sense of whether you are getting the result that you are looking for. If 2 looks good, then why do 3 or 4? Then stop and have your injector inject the same amount on the other side. If 2 looks good, and you want more, then open the 3rd one and continue. Perhaps 3 looks good, and you can stop. In my practice, my goal is to not make my patients look like they had any work done. At some point the, fill may start to look odd or puffy. So keep an eye on that, while you are having it done.If you want to be conservative, you can do this is more than one session. When you are swollen during the first few days after the first injection session you can use this as a "filler simulation" to determine whether or not you want more. You may feel that you look puffy when swollen instead of a sculpted, cheek augmented appearance. If that is the case, then cheek implants are firm implants placed on the bone which acts more like bone structure, without making the cheek fat plumper. One thing to note, the filler can add soft volume to the cheek which may look very cheeky and not sculpted, as you see in male models. If you look at male models they actually have relatively hollow faces with a cheek hollow below their cheekbone and pretty flat cheeks from a fat standpoint, but good bone structure.Hope that makes some sense.
