When it comes to maintaining natural expression while softening lines and restoring volume, RHA® (Resilient Hyaluronic Acid) offers a next-generation solution. Designed specifically for areas of the face in constant motion, RHA® adapts beautifully to facial movement—whether you’re smiling, frowning, or speaking—resulting in a more fluid, lifelike enhancement.

At Metropolis Dermatology in Pasadena, we provide RHA® filler treatments tailored to match your unique facial structure and aesthetic goals. These advanced injectables allow us to address fine lines and volume loss while preserving the natural dynamics of your face.

What Is RHA®?

RHA® is a state-of-the-art dermal filler formulated to mimic the natural hyaluronic acid found in your skin. What sets it apart from traditional fillers is its ability to remain resilient in high-movement areas. This means you get smoother, more youthful skin—without the frozen or overfilled look. Created using a gentle manufacturing process, RHA® retains more of HA’s natural structure, allowing it to blend seamlessly with your skin and move with your expressions.

 

What Does RHA® Treat?

RHA® is an ideal choice for treating dynamic wrinkles and areas where traditional fillers may look unnatural due to constant movement.

  • Expression lines: Smile lines, laugh lines, and frown lines that deepen with facial motion
  • Volume loss: Subtle replenishment in areas like the cheeks, lips, or temples
  • Elasticity concerns: Helps firm and restore youthful suppleness
  • Facial folds: Fills deeper creases, including nasolabial folds and marionette lines
  • Contour definition: Enhances facial shape and structure while maintaining fluid movement

 

Where Is RHA® Commonly Used?

RHA® is especially effective in regions of high mobility, including:

 

  • Nasolabial folds: Smooths the deep lines running from nose to mouth
  • Marionette lines: Softens creases below the corners of the mouth
  • Lips: Enhances volume without sacrificing softness or flexibility
  • Cheeks: Lifts and reshapes areas affected by volume loss
  • Crow’s feet: Reduces fine lines around the eyes—even when smiling

 

Why Choose RHA®?

Unlike conventional hyaluronic acid fillers, RHA® is designed to move naturally with your facial expressions, making it a go-to choice for people who want their enhancements to be discreet and realistic.

Key benefits of RHA® include:

  • Flexible structure: Designed to adjust with movement for a natural look
  • Long-lasting effects: Results can last 12 to 15 months
  • Gentle integration: Blends smoothly into the skin for subtle volume and support
  • Safe and effective: FDA-approved and clinically tested

 

What to Expect During Your Appointment

Treatments are straightforward and typically completed in under an hour.

  • Consultation: We’ll assess your goals and map out treatment areas.
  • Preparation: A topical anesthetic may be applied for comfort.
  • Injection: RHA® is injected using a fine needle or cannula into targeted areas.
  • Post-treatment: Minor redness or swelling is possible but usually resolves within 24 to 48 hours.

Most patients see immediate improvements, with final results settling in a few days.

 

How Long Does RHA® Last?

RHA® offers some of the longest-lasting results among dynamic fillers, with most patients enjoying results for 12 to 15 months. To maintain optimal results:

  • Avoid excessive sun exposure immediately post-treatment
  • Refrain from intense workouts for 24 hours
  • Stay hydrated and maintain a good skincare regimen

 

Who Is a Good Candidate?

You may be an excellent fit for RHA® if you:

  • Want to treat facial wrinkles without sacrificing expression
  • Are looking for subtle, flexible volume in areas that move frequently
  • Prefer a filler that blends naturally with your skin
  • Are in good health and not currently pregnant or breastfeeding

FAQs

Is the treatment painful?
RHA® injections are generally well tolerated. Topical numbing cream is used to enhance comfort.

How soon can I return to my routine?
Most people return to work or social activities right away. Mild swelling or redness is temporary.

Can RHA® be paired with other treatments?
Yes. Many patients combine RHA® with Botox® or skin treatments like microneedling for a more comprehensive result.

Are the results reversible?
Since RHA® is hyaluronic acid-based, it can be dissolved with hyaluronidase if needed.

How many treatments will I need?
Most patients only require one session, with touch-ups recommended annually or as needed.
