RHA Fillers

The RHA family of HA fillers are unique in that they are designed to resemble the natural HA present in the body by minimizing the amount of HA modification that occurs during the manufacturing process.  The idea is to have a more fluid and flexible filler and one that is less likely to result in reactions to the filler.  RHA fillers are designed to perform well in the most dynamic areas of the face without looking stiff or unnatural.



Results achieved with 0.6 mL of RHA® 2, 1.0 mL of RHA® 3, and 1.0 mL of RHA® 4 *Individual esults may vary

The RHA fillers are made with a gentle manufacturing process that helps preserve the natural structure of the hyaluronic acid, allowing it to more closely resemble the natural hyaluronic acid found in your skin. The three formulations in the RHA Collection are RHA 2, RHA 3, and RHA 4, with the higher numbers being more viscous and having more shaping power.  Your provider will help you determine which combination RHA filler is best for your treatment plan.



Results achieved with 1.0 mL of RHA® 3 and 2.0 mL of RHA® 4 *Individual results may vary.

What is the RHA Collection?

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

The current products in the RHA Collection are:

  • RHA 2 - ideal for superficial smoothing, radial cheek lines, perioral lines and lip augmentation

  • RHA 3 - appropriate for corners of the mouth, moderate nasolabial folds and the commissures

  • RHA 4 - best for deeper lines and folds, nasolabial and lower face, and the jawline

The RHA Collection has proven clinical effectiveness and duration comparable to other HA fillers such as Juvederm and Restylane.
