The advantage of Restylane is that it maintains its shape by using the body’s own natural moisture. As the hyaluronic acid slowly degrades, the molecules bind to water. Over time, the same volume can be maintained with a lesser amount of hyaluronic acid. The fact that the hyaluronic acid binds to water, helps the results last longer.
Restylane is free from animal proteins, minimizing the risk of allergic reactions to animal proteins. Temporary side effects include minor redness or swelling, which should disappear in a day or so.
