The RHA® Collection — resilient hyaluronic acid fillers made for the way your face moves.
Want filler that looks natural even when you smile and laugh?
The RHA® Collection of fillers is the only one FDA-approved to work for dynamic lines and wrinkles while moving naturally with your face. ZENA Medical proudly offers this collection, which is only available to a select group of providers. While some dermal fillers can give a stiff, unnatural appearance when used in mobile parts of the face, the RHA® Collection matches the motion and appearance of your skin better for a smooth, natural-looking result.
The ZENA Medical team has a unique approach to dermal fillers, selecting from all the fillers available like an artist’s palette to create a subtle and natural-looking facial enhancement. Our experts can restore volume loss and achieve balance while ensuring that you never look overdone.
The RHA® Collection uses hyaluronic acid, a complex sugar molecule found abundantly in young skin. Its unique manufacturing process lets the hyaluronic acid stay closer to its natural form. This allows it to interact with the skin more naturally. RHA® stands for Resilient Hyaluronic Acid, a more flexible and lasting formula that adapts to your facial movement, providing a more natural look at rest and in motion.
RHA® is a flexible filler for a face in motion. Most dermal fillers work on static lines and wrinkles. These wrinkles remain visible whether your face is active or resting. They typically result from increased skin laxity and sagging. Dynamic wrinkles form in areas where facial muscles pull on the skin during facial motion. They are often called expression lines because they form in regions that crease during facial expressions like smiling, frowning, or laughing. The flexible, natural-looking RHA® Collection moves with these dynamic lines and wrinkles so they can be used to treat areas other fillers cannot.
RHA is available in three strengths to ensure the best fit for your needs.
Because hyaluronic acid occurs naturally in the skin, the RHA® Collection is safe for almost anyone. If you want a more natural-looking solution for your lines and wrinkles, even those other fillers do not treat, the RHA® Collection offers a unique option.
Depending on the number of areas you have treated, your session may take 15 to 20 minutes. The injections feel like a slight pinch, and most people find them very tolerable. You can schedule an RHA® Collection appointment during a break in your schedule and return to your planned activities immediately afterward.
You will see your lines and wrinkles become smoother and softer almost immediately. The superior resilience of the RHA® Collection means it can move with your features with no sign of stiffness or an unnatural look.
You will not have any downtime after getting RHA® Collection fillers. As with other injectables, some people notice red spots or minor bruises in the injection areas. These will disappear within a few days.
The RHA (Resilient Hyaluronic Acid) Collection is a line of fillers designed specifically for the dynamic, expressive areas of the face. Their manufacturing preserves a more natural HA structure, so they stretch and recoil with movement — helping you look refreshed while smiling, talking, and laughing, not just at rest.
RHA 2 addresses fine lines, RHA 3 and RHA 4 restore volume in deeper folds like the nasolabial and marionette lines, and RHA Redensity refines delicate lines around the mouth. Because they move with your face, they’re a favorite for patients who want a result that never looks stiff.
RHA fillers typically last up to 15 months. Treatments at ZENA Medical are performed by board-certified dermatologist Dr. Zena Gabriel in Newport Beach, with an emphasis on natural, expression-friendly results. Book a consultation to see if RHA is right for you.
