I have been reading about the different injectable fillers (Juvederm, Perlane, Radiesse, Restylane) and don’t really understand their differences. What differentiates them, and how are they used?
Juvederm, Perlane and Restylane are hyaluronic acid fillers. Hyaluronic acid is a protein in our skin that along with collagen acts as a matrix and support for skin cells. These fillers use synthetically produced hyaluronic acid to plump, augment and rejuvenate various areas of the face. Although all are FDA approved for limited areas only they are commonly used to fill cheek folds, fine lines, augment lips, tear trough areas and other hollows. They are very safe and usually last 6 months on average. Radiesse is made of hydroxyapatite crystals which are calcium crystals that form the non cellular matrix of our bones. It has many uses in dental, orthopedic and laryngeal augmentation and support. As a cosmetic filler it is most often used to fill deep folds and lines and to add volume to cheeks. It is not suitable for lips or areas of thin skin. On average it lasts about 9-12 months.
