The RHA® Collection is the first and only FDA-approved hyaluronic acid fillers for dynamic wrinkles and folds and include three approved formulas: RHA® 2, RHA® 3, and RHA® 4.

How is the RHA® Collection different than other dermal fillers?

The RHA® Collection of hyaluronic acid fillers are the only FDA-approved hyaluronic acid fillers for dynamic wrinkles and folds. Like other HA dermal fillers, RHA® is made from hyaluronic acid—but RHA® is different because it’s made differently. RHA® uses a gentle manufacturing process. This process helps preserve the natural structure of the HA, helping it mimic the natural HA found in your skin. RHA® is the latest advancement in HA filler technology, purposely designed to perform in the most dynamic areas of the face without looking stiff or unnatural.

The RHA® Collection is designed to be long-lasting—with proven clinical effectiveness and duration up to 15 months.


The resilient hyaluronic acid found in RHA fillers is much more malleable than traditional hyaluronic acid. It can recoil and spring back to fill in expression lines without making the face look resistant to movement. The resilience of RHA fillers is an essential quality when treating dynamic areas of the face like the skin around the eyes and mouth.

Each of RHA fillers is that they each contain a small amount of lidocaine, a local anesthetic, to minimize pain or discomfort during the injections.

Types of RHA Fillers

The RHA line contains three grades of filler products; each number represents the concentration of hyaluronic acid.

RHA2  - has the lowest concentration of hyaluronic acid and is used for moderate dynamic wrinkles and folds, such as lines in between the eyebrows or around the corners of the mouth.


RHA3 - has a higher concentration of hyaluronic acid and is used for deeper dynamic wrinkles and folds, such as nasolabial folds extending from the corners of the nose to the mouth.

RHA4 -has the highest concentration of hyaluronic acid and is used for severe dynamic wrinkles and folds, including nasolabial folds and folds around the jawline or cheekbone area.


Am I a candidate?

Before any treatment, we would first have a consultation with you to discuss options regarding dermal fillers. During your consultation one of our providers would go over your aesthetic goals regarding fillers and assess your area of concern. At that time recommendations would be made about which RHA® Collection filler is best for you. There are three formulations of RHA® in the collection. Your provider will determine which formulation is best for you.
