STYLAGE® XXL is a gel made of cross-linked hyaluronic acid that does not have an animal origin, along with an antioxidant, Mannitol. This injectable implant is apyrogenic, has a physiological pH and osmolarity, and comes in a 2.2ml pre-filled syringe that has been sterilized using heat autoclaving techniques. STYLAGE® XXL adds volume to the skin tissue before gradually being absorbed into the body. Injecting STYLAGE® XXL subcutaneously or into the deep dermis can augment or restore volume to the cheeks or facial oval, correct ptoses, or treat facial lipodystrophy especially in HIV patients. For the best treatments results, precision is needed, so only medical personnel who have specifically been trained to inject dermal fillers should administer STYLAGE® XXL.
