What is a Hyaluronic Acid Filler?
Hyaluronic acid is a compound naturally occurring in the human body. As people age, the amount of hyaluronic acid in skin tissue decreases, leading to wrinkles, lines, and a reduction in volume. Restylane and Juvederm are both forms of hyaluronic acid fillers. When injected into the face, hyaluronic acid fillers can create a younger, fuller appearance. Although identical in composition, these products have some differences and may be used for different purposes.
What Is Restylane?
Restylane is an FDA-approved hyaluronic acid filler commonly used as a cosmetic injection to minimize facial lines and wrinkles. Restylane is also used to add volume to lips, cheeks, and chin. This filler is injected into the facial skin and molded into position. Recovery time is generally two to three days.
Advantages of Restylane
As a cohesive material, Restylane will stay in place once injected and will not drift into adjacent tissues. The filler can be used to add volume to areas of the face such as the lower eyelid, lips, and so on. Restylane also comes in various amounts and sizes. This means smaller procedures will require a smaller injection and thus will be less expensive.
Because Restylane has a more clumpy consistency, it will require some arrangement within the tissues. This process can be difficult for dermatologists and doctors who are not trained in this type of manipulation. Restylane may also cause more severe bruising than other hyaluronic acid fillers. In addition, the effects of Restylane generally do not last as long as Juvederm.
What Is Juvederm?
Juvederm is “cross-linked.” Cross-linking is a chemical process that binds the chains of hyaluronic acid together in a gel-like material. In short, this process changes the natural form of hyaluronic acid, which is liquid, into a gel. In comparison to the liquid form, the effects of this gel last much longer when injected into the face. In addition, the gel is generally easier for doctors and dermatologists to work with.
Juvederm is advertised as having a smoother appearance and feel than other hyaluronic acid fillers. This quality can be advantageous for dermatologists and physicians who prefer not to mold the substance into tissues. Juvederm can simply be injected into desired areas and left in place. The effects last between 9 to 12 months.
Although smoother than Restylane, Juvederm can creep into neighboring tissues, creating an uneven appearance. It can also cause excessive swelling in some patients. Juvederm may be slightly more expensive than Restylane as Juvederm comes in only one syringe size. Material may be wasted when doing small corrections of the face, leading to a higher cost per procedure.
