Hyaluronic acid is a natural substance in the skin that delivers nutrients, helps the skin retain moisture and softness, and adds volume. This natural substance is found in almost every single living thing. In humans, hyaluronic acid acts as a network that transfers essential nutrients from the bloodstream to skin cells.

The RHA® Collection is the only line of FDA-approved HA fillers for dynamic lines, wrinkles, and folds. Using a gentle manufacturing process to help preserve the natural structure of hyaluronic acid, RHA is able to more closely resemble the hyaluronic acid in your skin.

Repetitive movements – like laughing and talking – create facial lines called dynamic wrinkles and folds. The RHA® Collection is designed to be resilient enough to adapt to your dynamic facial movements for a look that’s beautiful at rest and flawless in motion.

These long-lasting fillers can last up to 15 months in dynamic wrinkles and folds and 1 year in lipstick lines.

The RHA® Collection includes four hyaluronic acid 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.
  • RHA® 4 provides natural volume for deeper dynamic wrinkles and folds.
