Hyaluronic Acid Filler - What's the Source?

Is it made by chemical process or obtained from animals? I would like to know how the substance is obtained and how safe it is to inject into the face.

Restylane is made of hyaluronic acid, which occurs naturally in the body. It is not manufactured using animal proteins and is very safe. In the thousands of treatments we have performed at our facilities we have never had a patient react negatively in any way to a Restylane injection.
