Since the approval of Restylane by the FDA in 2005 with Juvéderm following in 2006, dermal fillers have been a popular feature of the aesthetic world. In fact, after Botox, those two dermal fillers are the most popular cosmetic injectables around the globe.
But now you could say there’s a new kid in Atlanta — Resilient Hyaluronic Acid dermal fillers, RHA fillers for short. They’ve been available in Europe for over five years, but recently received FDA approval for the U.S. market.
Dr. Beaty is offering all three Teoxane RHA fillers at our locations in Alpharetta and Atlanta. And if you come in today, you’ll be loving your erased nasolabial folds and marionette lines for all your holiday parties.
What are RHA fillers?
RHA stands for resilient hyaluronic acid, and this is the latest advance in dermal filler science. These fillers are designed for the dynamics of our facial movements, so the volume they provide looks more natural and adapts to movement without breaking down as quickly.
There are currently three available Teoxane RHA dermal fillers, RHA 2, RHA 3, and RHA 4. These are marketed in the U.S. by Revance.
What is the difference between RHA fillers and regular dermal fillers?
Most people have heard of Juvéderm and Restylane, along with their respective families of dermal fillers. These fillers are made from hyaluronic acid, a naturally occurring substance in the human body (and most other mammals) that is responsible for hydrating, plumping, and firming the skin. Hyaluronic acid does this by binding with nearby water molecules.
These fillers have provided great results, but sometimes they don’t respond as well when the patient’s face moves with expressions and the like. That’s because hyaluronic acid breaks down rapidly and is metabolized in about 48 hours. To prevent this from happening, with first-generation dermal fillers the HA is crosslinked with suspended chemical proteins. These proteins make the HA in first-generation dermal fillers not as malleable with facial movements.
The difference between RHA and first-generation hyaluronic acid dermal fillers is that these new fillers have fewer chemical modifications and crosslinking in longer chains of HA. This makes RHA fillers closer to the natural hyaluronic acid that is found throughout the human body in their flexibility in usage, natural-looking results, and longevity of results. Basically, RHA fillers are closer to natural hyaluronic acid, so they are undetectable regardless of facial movements. That’s the improvement RHA fillers make over the first-generation HA fillers.
