Restylane Lyft (formerly known as Perlane) is an FDA-approved, hyaluronic acid filler. There are a variety of hyaluronic acid fillers available in the United States (Restylane, Restylane Silk, Juvederm, Voluma, Volbella, Belotero, etc) which all differ slightly in their specific properties and applications.
Restylane Lyft is a firm, dense gel, that is formulated with large particles of hyaluronic acid. As a result, it is best used for deep injections on the cheekbones, to help lift and contour the cheeks, however it can be used in other areas of the face as well. The results from Restylane Lyft can last for up to one year after treatment. I recommend that you schedule a consultation with a cosmetic dermatologist or plastic surgeon to further discuss your concerns, and to figure out the best treatment plan for your needs.
