RHA Dermal Fillers

Dermal fillers are known for adding volume and smoothing lines and static wrinkles on the face, neck, and even hands, while patients have long relied on neuromodulators to relax their dynamic wrinkles. With the recent FDA approval of Revance RHA® Dermal Fillers, patients may now experience the benefits of dermal fillers for their dynamic facial wrinkles.

Coast Dermatology & Laser Surgery Center offers the RHA family of dermal fillers to our Laguna Beach, California patients. Our team of board-certified dermatologists and licensed medical professionals has been serving our community with cosmetic and medical dermatological treatments for 30 years, remaining focused on our patients’ skincare health and beauty.

What Are RHA Dermal Fillers?

RHA Dermal Fillers are the latest products from TEOXANE Laboratories and the first HA (hyaluronic acid) dermal fillers to be FDA-approved for treating dynamic wrinkles. This family of fillers is formulated with the face’s constant motion in mind; they are strong enough to fill out lines and folds, but pliable enough to move with you. RHA fillers (RHA® 2, RHA® 3, and RHA® 4) are each individually prepared to treat varying intensities of facial wrinkles.

How Do RHA Fillers Treat Dynamic Wrinkles?

RHA Dermal Fillers work in the mid-to-deep dermis or deep dermis to superficial subcutaneous tissue to treat dynamic wrinkles and folds from within. Our board-certified dermatologists and expert injectors will place the RHA filler as deep as necessary to achieve optimal results for your specific needs and goals. These fillers can fill in dynamic wrinkles without stiffening your face. They adapt to your facial movements, allowing you to keep a natural look when your face is at rest or in motion.

This family of fillers is resilient because of their gentle manufacturing process. The natural structure of the HA remains intact, which helps provide moisture, volume, and structure to the skin. HA is what enables RHA fillers to mimic natural properties within the skin, allowing the filler to move more easily with facial movements, like smiling, squinting, or frowning.

Benefits of RHA Dermal Fillers

Unlike neuromodulators, RHA fillers are made to adapt to facial movements, not prevent them. The hyaluronic acid in these fillers closely mimics the HA naturally found in your skin, allowing the fillers to provide structure while softening your appearance. Other benefits include:

  • Offer long-lasting results as compared to other fillers as they take longer to break down because of their flexibility
  • Last much longer than neuromodulators that are also used to treat dynamic wrinkles (9-18 months for RHA fillers vs. 3-6 months for neuromodulators)
  • Provide natural appearance while correcting facial wrinkles and folds
  • Address many concerns, such as dynamic wrinkles, nasolabial folds, expression lines around the mouth, marionette lines, and chin lines
  • Sculpt and balance facial proportions
  • Restore volume to areas such as cheeks, chin, jawline, and lips

While these benefits are true for all of the fillers in the RHA family, each of the products offers specific benefits and possibilities for facial rejuvenation.


For moderate dynamic wrinkles, RHA 2 is usually best. We inject this product in the mid-to-deep dermis to treat wrinkles on the upper face such as the forehead, crow’s feet, and glabella. You can also use this product to enhance and contour the lips, as well as treat fine lines around the mouth.

Severe dynamic wrinkles are best treated by RHA 3. We also inject this product in the mid-to-deep dermis, but in areas with deeper wrinkles. Nasolabial folds and vertical lip lines are common areas for RHA 3 to treat as these creases are generally more defined than those on the upper face. We can also use this filler to add volume and pleasing contours to the cheeks and lips.


RHA 4 is the most robust filler in this family, and we use it to treat dynamic extended areas such as the cheeks and upper cheeks. Treatment in these areas can correct deep skin depressions and contour the face. We place this filler in the deep dermal and superficial subcutaneous tissue, where it can provide superior results on even advanced signs of aging.

RHA Dermal Fillers vs Neuromodulators

Until now, only neuromodulators could treat the dynamic areas of the face described above. While neuromodulators like Botox Cosmetic have been and continue to be effective in treating dynamic facial wrinkles, they aim to relax the underlying muscles, which can limit a patient’s ability to make the same expressive movements with their face as before. RHA dermal fillers actually add volume to the face, essentially “filling in” wrinkles rather than interacting with facial muscles. These fillers are made of hyaluronic acid, which is naturally found in your skin, while neuromodulators contain a different active ingredient designed to target facial muscles.

Both types of injectables can be safe and effective for patients, so we’ll help you select the best option for your unique facial structure and aesthetic goals at your consultation.

Which wrinkle treatment is right for me?

Wrinkles appear due to aging and external influences like sun exposure. Everyone’s face is structured differently, so no two faces age exactly the same way. At your consultation, our board-certified dermatologists will analyze your skin and listen to your goals to recommend treatment options for you.

Are RHA injections painful?

Each of the RHA fillers contains a small amount of lidocaine, a numbing agent. This helps minimize discomfort during your treatment session. We also offer topical numbing to increase patient comfort.

Are there any possible side effects from RHA fillers?

Side effects from RHA injections are temporary and may include redness, mild swelling, or bruising at injection sites.
