RESTYLANE® SUBQ is made of stabilized hyaluronic acid that does not have an animal origin. This transparent, sterile gel comes in a glass syringe with a luer-lock fitting. Inject RESTYLANE® SUBQ for facial augmentation, shaping the contours of facial features for more pronounced cheeks, a more defined chin, or other uses. Depending on the treatment area, the injection depth will vary from subcutaneously to supraperiostally. Over time, RESTYLANE® SUBQ will experience isovolemic degradation, maintaining its volume even as it breaks down. Only authorized medical personnel with experience correcting facial volume should administer RESTYLANE® SUBQ.
