From Dr. Lampert:
Hyaluronic Acid Gel based injectable fillers such as Restylane, Juvederm, Restylane Silk, and Perlane (now rebranded as Restylane Lyft) provide temporary soft tissue volume without surgery. There are many different fillers, but for lip augmentation I currently only use hyaluronic acid based products or, alternatively, the patient's own fat with micro fat grafting. This young lady, shown immediately post injection, had a total of 1 cc of hyaluronic acid injected to the upper and lower lips for lip augmentation. She desired a natural more "hydrated" volume without the "duck lips" look.X
