In addition to its more common usages in the nasolabial folds (the lines between the nose and the edge of the mouth), and in the marionette lines (lines extending at the underside of the lower lip) Restylane can be used to contour the jawline and even in the temporal (just in front of the sideburns) areas, as well as in the cheeks. For the jawline itself, other products, such as Radiesse and Sculptra, are often used, and can be very effective. In my view, the most important aspect of a successful injectable contouring session is not the product used, but the surgeon using the product. I would advise spending more time choosing the treating surgeon and deciding together on the best filler for your particular situation, rather than focusing on the particular choice of filler.
