About Dermal fillers. Dermal fillers are causally known as wrinkle fillers but they do so much more than that. Most dermal fillers are based on hyaluronic acid ( Juvederm®, Restylane®, Belotero® Balance ) but they can also be composed of Calcium Hydroxylapatite CaHA ( Radiesse® ), Poly-L-latic Acid ( Sculptra® ) or Polymethylmethacrylate PMMA ( like Ballafill® ). They are injectable treatments used to fill wrinkles, restore facial volume and contour and enhance lips. They also provide excellent hydration and boost collagen production for long-lasting instant results.
