Dermal fillers, naturally-derived hyaluronans, such as Perlane® and Radiesse® from the Juvéderm® and Restylane® product lines, are directly injected into skin with the purpose of plumping and lifting that area to the point where the wrinkle, depression, or fold is gone. Bellafill® and Sculptra® work to add volume by “restructuring” the skin’s collagen network. Facial contours are instantly restored. Without surgery or downtime, dermal fillers can restore the temples and under-eye (sulcus) hollows, plump the cheeks, improve folds around the mouth or between the brows, enhance the lips and lip borders, reshape the nose and facial contours and more. Patients can expect to return immediately to regular activities. Depending on the type of filler, the effects can last anywhere from six months to two years.
