RHA Dynamic Facial Fillers

RHA® Collection

RestylaneRHA, or Resilient Hyaluronic Acid, is the latest advancement in hyaluronic acid filler technology — purposely designed to treat dynamic areas of the face.

Manufactured to more closely resemble the skin's natural hyaluronic acid, it comes in a variety of formuas for more refined, more natural, and longer lasting results.

  • RHA Redensity is an FDA-approved weightless filler to smooth moderate to severe wrinkles in adults aged 22 and up.
  • RHA® 2 and  RHA® 3  offer soft and natural smoothing of wrinkles and folds.
  • RHA 3® is FDA approved for lips and for moderate to severe dynamic wrinkles and folds, such as nasolabial folds.
  • RHA® 4 provides natural volume for deeper dynamic wrinkles and folds.

These long-lasting fillers can last up to 15 months in dynamic wrinkles and folds, and 1 year in lipstick lines. Dr. Hamori or Dr. DiEdwardo can customize a treatment plan for your desired goals.

RHA Collection of Fillers Illustrated

Designed for facial dynamics

Our faces are constantly moving, making millions of movements and expressions each day — talking, smiling, frowning, laughing. All of these repetitive movements over time create dynamic lines and folds. Treating these dynamic lines with traditional fillers and neurotoxins can sometimes create a stiff or unnatural appearance when our faces making those many micro movements.

The RHA Collection was specifically designed to perform in this dynamic environment. The formulas are resilient to adapt to dynamic facial movements.

Dynamic fillers for the lips

Both RHA® 3 and RHA Redensity are FDA approved for treatment of aging lips and the lip area — one of the most dynamic facial areas.  These two unique formulations are designed for dynamic facial movement.

Designed for a natural look

Our skin naturally contains hyaluronic acid. This is what provides moisture, volume and  structure to youthful skin. As we age, we produce less hyaluronic acid, and we turn to dermal fillers. The RHA Collection's uniquely manufactured resilient hyaluronic acid provides a product that most closely resembles the natural hyaluronic acid in our skin. This creates a more natural, more dynamic result.
