What is the RHA Collection?

The RHA (Resilient Hyaluronic Acid) Collection is a line of FDA-approved dermal fillers designed to mimic natural hyaluronic acid and flex with facial expressions. Unlike traditional fillers, RHA is formulated to withstand dynamic movement, providing natural-looking results even during animation.

What makes RHA fillers different from other fillers?

RHA fillers are manufactured using a gentler process that preserves long HA chains, making them more resilient and capable of withstanding facial movement. They are especially well-suited for areas with significant expression movement such as around the mouth and mid-face.

How long does the RHA Collection last?

Clinical studies show RHA fillers last up to 15 months. RHA Redensity is formulated for superficial fine lines; RHA 2, 3, and 4 address progressively deeper wrinkles and greater volume needs.

Which RHA product is right for me?

RHA Redensity treats under-eye and fine surface lines; RHA 2 addresses moderate wrinkles; RHA 3 treats deeper folds; RHA 4 is for high-movement areas needing significant volume. Your Naya Wellness injector will assess your anatomy and recommend the right product during your appointment.

Is the RHA Collection safe?

Yes. The RHA Collection is FDA-approved with an established safety profile. Like all HA fillers, RHA is reversible with hyaluronidase. At Naya Aesthetics, all injections are performed by licensed medical professionals using sterile technique.

At Naya Aesthetics, we offer the RHA Collection of resilient hyaluronic acid (HA) fillers, the only line of FDA-approved HA fillers designed to adapt to facial movement. Engineered with Swiss innovation, RHA fillers maintain their integrity even in dynamic areas such as the cheeks, nasolabial folds, lips, and perioral lines—delivering natural-looking results that move with your face.

Scientifically Engineered for Facial Movement

Unlike traditional HA fillers, the RHA® Collection is manufactured using a gentle, proprietary process that preserves the long HA chains found naturally in the skin. This results in a filler that mimics the natural HA found in youthful skin and provides improved durability and elasticity in dynamic facial areas. According to clinical studies published in Aesthetic Surgery Journal (2020), RHA fillers maintain results for up to 15 months with high patient satisfaction and minimal side effects.

FDA-Approved and Clinically Validated

RHA 2 and RHA 3: Ideal for moderate to severe dynamic wrinkles and folds such as nasolabial folds and marionette lines.
RHA 4: Formulated for deeper lines and volume replacement in areas like the cheeks and lower face.
