Thank you for posting your interesting question. Most of the aging of the face is due to loss of bone and remodeling of facial bones. Midface lifts have limited indications, often do not replace the lost bone volume, do not address jowls or neck issues, and have problems with pulling down the lower eyelid, unless anchored properly. Fillers today have evolved significantly since the days of collagen. Sculptra, Radiesse and Voluma are excellent products to restore the loss of mid face volume leading to a characteristic aged appearance. These products, when injected artistically and in the proper volumes, restore the youthful volume and convexities of the face, producing beautiful and natural results. I recommend that you bring a photograph from a few years ago along, on your cell phone, to your consultation with a Board Certified Plastic Surgeon who is experienced with non surgical facial rejuvenation. At the time of your consultation, you will be examined, discuss your goals, have all of your questions answered and have a plan as to which products and how many will be required to deliver natural results. Best wishes, Richard Wellington Swift, M.D.
