Is restylane subq used in the USA? And is it FDA approved?

I have practices on both the Upper East Side of Manhattan and in Raanana, Israel. Unlike in Israel and Europe, Restylane SQ is not approved in the U.S. With the introduction of so many new and robust volumizing fillers, particularly in Israel, in recent years I have been using SQ far less than in the past. I have found products such as Emervel Volume, Stylage XXL, and Voluma XC (now also available in the U.S.) to yield equally long-lasting, but smoother results compared to SQ. 

In the US only restylane L, restylane silk and restylane Lyft are approved by the US FDA.  Best, Dr. Emer.

there was always a form of subcutaneous Restylane in the United States. It was called perlane. I think they just changed the name
