While Allergan’s Juvederm® and Galderma’s Restylane® filler collections are some of the most popular options for reducing static wrinkles and enhancing facial contours, a new filler has recently been introduced in the United States. RHA® Revance fillers are now available. So how do these new fillers compare to other standard hyaluronic acid-based gels? Here’s a basic rundown of some of the similarities and differences between traditional types of fillers and the newer RHA® fillers at our Philadelphia area practice.
Both RHA® fillers and earlier types of volume-adding injectables, like Juvederm®, contain hyaluronic acid as their main ingredient. However, due to the way it’s processed—with fewer chemical modifications and preservatives—the hyaluronic acid contained in RHA® is purer and more similar to the natural hyaluronic acid found in our bodies.
At one point, the only option for reducing dynamic wrinkles caused by repetitive facial movements was with neuromodulator injections to block the messages between nerves and muscles, thereby reducing furrow-causing muscle contractions. RHA® Revance fillers are the first hyaluronic acid fillers to be FDA approved for minimizing dynamic wrinkles and folds, which sets them apart from Juvederm®, which is intended for improving static wrinkles caused by collagen loss and intrinsic aging. Much like their Juvederm® counterparts, RHA® Revance fillers are typically used on the center and lower part of the face for moderate to severe wrinkles around the nose, lips, and mouth. RHA® can also improve facial contours.
RHA® integrates well, stretches, and adapts easily to facial movements when you talk or make facial expressions. This allows it to look more natural when compared to fillers that have a tendency to remain in one place. Due to the way RHA® fillers are formulated, it typically takes a longer time (15 months) for the hyaluronic acid to be metabolized, so they may have a longer lifespan when compared to other hyaluronic acid facial fillers (12 months). However, RHA® fillers do not last as long as Juvederm®’s Vycross fillers like Voluma® and Vollure®.
