Experience the first and only FDA-approved hyaluronic acid fillers designed for dynamic facial movement, delivering natural results at rest and in motion.
What Is the RHA® Collection?
RHA stands for Resilient Hyaluronic Acid. The RHA Collection is a line of dermal fillers developed in Switzerland using a gentle manufacturing process that preserves the natural structure of hyaluronic acid. This makes RHA fillers behave more like the HA naturally found in your skin.
Traditional fillers can sometimes look stiff or unnatural when your face moves. RHA fillers are specifically designed to stretch and adapt to facial expressions, such as smiling, laughing, and talking. The result is smooth, natural-looking correction, whether your face is at rest or in motion.
The RHA Collection includes multiple formulations:
- RHA 2: ideal for moderate lines and lip enhancement
- RHA 3: treats deeper folds like nasolabial lines and marionette lines
- RHA 4: addresses severe folds and provides structural support
- RHA Redensity: the first FDA-approved filler for superficial lip lines
