As we age, we lose volume in our faces, resulting in flat cheeks, hollows under our eyes, and sagging of jowls. We develop wrinkles around our eyes and mouth, as well as deepening of the nasolabial folds (parentheses lines) and marionette lines (downturned smile). Fillers are injected into the skin to “fill” areas such as wrinkles, folds, hollows, or scars to restore the skin to a smoother, more youthful contour. Fillers can also be used to augment areas such as the cheeks or lips. The world of fillers has blossomed in recent years and there is now a wide choice of fillers to choose from. Factors to consider when choosing a filler include; the expected duration of results, number of syringes required for full correction, number of sessions required, cost, and the skill and experience of the injector. Fillers are very technique sensitive and your final cosmetic result is highly dependent on who is injecting the product into your skin.
