Restylane is a very popular and effective hyaluronic acid-base dermal filler. It has been used widely throughout the face for the correction of deep lines and wrinkles. The active ingredient in Restylane is hyaluronic acid. This is the same ingredient that is in the ground substance of human skin. They do not add silicone to Restylane.
Two entirely different substances. Agree with Dr. Persky. If your injector is practicing in a hotel room, or any situation where you think 60 minute cameras should be there instead of you, it's time to exit stage left as that great American wit Snagglepuss was wont to remark.
