Dermal fillers designed specifically for facial movement. The RHA® (Resilient Hyaluronic Acid) Collection is the first and only FDA-approved line of fillers engineered to adapt to your dynamic facial expressions—smoothing active lines without looking stiff, heavy, or unnatural.
How does RHA® differ from Botox if both treat dynamic lines?
Botox temporarily relaxes the underlying muscles that cause skin to crease. RHA® is a dermal filler that sits in the skin to physically smooth existing creases while stretching and flexing with your facial movements. They treat dynamic areas differently and are frequently paired together.
How long does RHA® filler last?
Clinical studies show RHA® maintains its structure for up to 15 months, making it one of the longest-lasting HA fillers designed specifically for high-movement facial zones.
Will RHA® fillers migrate or move to other parts of my face over time?
No. RHA® is engineered with high tissue integration and cohesivity. Rather than sliding or shifting under muscle pressure, the gel adapts locally—stretching when your muscles move and springing back to place when your face resets.
