Most patients considering filler injections have noticed early signs of aging, such as nasolabial folds, smile lines, or volume loss in the cheeks. Fillers restore volume but don't lift sagging or loose skin. Good candidates for fillers should have skin that retains much of its elasticity. Additionally, younger patients who want to create more angular facial contours, such as a streamlined jaw, higher cheekbones, or narrower nose, can get fillers to achieve those goals.
