How is the RHA® Collection different than conventional fillers?

The RHA® Collection is the only line of FDA-approved HA fillers for dynamic lines, wrinkles, and folds. The RHA® Collection offers four HA-filler formulations. RHA Redensity™ is a weightless filler that smooths delicate lipstick lines. RHA® 2 and RHA® 3 offer elegant and refined smoothing for those seeking a soft, natural look in wrinkles and folds. Lastly, RHA® 4 provides natural volume for deeper dynamic wrinkles and folds. The RHA® Collection uses a gentle manufacturing process with minimal chemical modifications to the initial composition. This helps preserve the structure of HA, helping it more closely resemble the natural HA found in the skin. The RHA® Collection is the latest advancement in HA-filler technology—purposely designed to treat dynamic areas of the face. The RHA® Collection was developed by the innovative Swiss company, TEOXANE, and has been widely used by aesthetic experts outside of the US since 2015. TEOXANE was founded by Madame Valerie Taupin who co-created the dermal filler Juvéderm® two decades ago, looking to perfect dermal-filler technology. She then directed her research team to design an HA filler to more closely mimic HA in the skin—leading to the latest filler innovation in the market: RHA® Collection.
