Restylane® is a revolutionary, nonallergenic dermal filler from Sweden that offers exceptional, long-lasting results. With Restylane®, Dr. Terracina can smooth facial lines and wrinkles, add body and contour to lips, and sculpt the cheeks and mouth. This highly effective cosmetic filler is made of hyaluronic acid, a biodegradable substance that occurs naturally in all living beings. Its natural function in the human body is to provide volume and pliability to the skin. Hyaluronic acid is capable of binding with water up to 1,000 times its weight in water, so even as a Restylane® treatment begins to naturally degrade, it continues to attract water. This is why Restylane® lasts up to 60 percent longer than collagen fillers. Clinical trials have shown that lip augmentation treatments with Restylane® last up to six months, and facial contouring treatments last up to 12 months. Because it is so effective, Dr. Terracina often uses Restylane® to enhance the results of a neck lift or eyelid surgery. Our patients appreciate the fact that, because Restylane® is derived from a natural substance, no skin test is necessary prior to treatment.
