What is the RHA Collection?

The RHA Collection is a new collection of hyaluronic acid fillers like Juvéderm or Restylane. Hyaluronic acid (HA) is a molecule naturally found in the skin and is responsible for keeping it soft, supple, and youthful. In the form of an injectable dermal filler, HA can restore volume and enhance the natural features. The RHA Collection offers you even more confidence-boosting options along with our other fillers and injectable treatments.

Is the RHA Collection Right for Me?

The RHA Collection is a great option for patients who are new to fillers or who want to explore natural-looking ways to reduce signs of aging and enhance areas like the lips – without compromising natural expressions. RHA fillers produce instant results and require no downtime, making them a great way to refresh your look. Our knowledgeable injectors can help you explore the best options from the RHA Collection during a consultation:


RHA Redensity is the lightest and smoothest filler in the RHA collection. It’s one of the best options available for areas like the lips or undereyes that can benefit from minimal volume. Redensity can smooth fine lines around the mouth and add hydration to the lips, as well as gently fill in undereye troughs.

RHA 2 and 3

RHA 2 and RHA 3 are medium-thickness fillers that work best in the lower face, filling in concerns like nasolabial lines or marionette lines without impacting expressions. Versus other fillers of the same thickness, RHA 2 and 3 are incredibly flexible and great options for dynamic areas.


RHA 4 is the thickest option of the RHA Collection and provides natural-looking volume for deeper lines and folds, as well as areas of contour deficiency like the jawline or cheeks. RHA 4 provides the most stable and long-lasting volume of the RHA Collection.

What are the Benefits of the RHA Collection?

  • Immediate results
  • No downtime required
  • Quick and easy treatment

What Happens During RHA Treatment?

To begin, you’ll discuss your cosmetic goals with our team so together we can select the best filler option for your needs. The injection process is incredibly quick, and you can refine your results before you return home.

RHA Collection Maintenance

RHA fillers can last up to 15 months, with thicker formulations like RHA 4 lasting the longest and Redensity lasting the shortest amount of time. Our team will ensure you understand when to return for your touch-up treatment. After your session, you may have some slight redness and sensitivity at the injection sites. We recommend you avoid blood-thinning medications before and after your treatment to reduce the chances of bruising. We also recommend keeping your head elevated. Although you’ll see instant improvement after your session, it can take up to two weeks for your final results to settle in.
