The RHA Collection® is a family of hyaluronic acid (HA) dermal fillers designed specifically for dynamic facial wrinkles and folds—the lines that appear when you smile, laugh, talk, or make facial expressions.

"RHA" stands for Resilient Hyaluronic Acid. These fillers are manufactured using a process that preserves more of the natural structure of hyaluronic acid, allowing the filler to move more naturally with facial expressions.

The collection includes:

• RHA Redensity™
• RHA 2
• RHA 3
• RHA 4

Each product is designed for different depths of wrinkles and levels of volume correction.

How Does the RHA Collection Work?

Like other hyaluronic acid fillers, RHA:

1. Adds volume beneath the skin
2. Attracts and retains water
3. Supports facial tissues
4. Smooths wrinkles and folds

What makes RHA unique is its focus on dynamic movement.

The filler is formulated to:

• Stretch and compress naturally
• Move with facial expressions
• Maintain a soft, natural look while talking, smiling, and laughing

This is why many providers call RHA a "dynamic filler."
