LOGO-INJECTORJust like RESTYLANE®, PERLANE® and PERLANE-L® are hyaluronic acid fillers made like cut up Jello suspended in a liquid. PERLANE® is more concentrated than RESTYLANE®, and therefore it is very good for longer lasting effect and to volumize deeper areas, such as the tear trough below the eyes. PERLANE® also is not as hydrophilic as JUVEDERM®, which also makes it ideal for around the eyes.
