RHA Filler Guide: The Collection That Moves With You

Most fillers are engineered to hold shape. RHA fillers are engineered to move — designed specifically for the parts of your face that talk, smile, and laugh. This guide covers everything you need to know about RHA 2, RHA 3, and RHA 4 at RELUXE Med Spa in Westfield and Carmel, Indiana.

What Is RHA?

A filler designed for faces that move

RHA stands for Resilient Hyaluronic Acid. The collection is made by Revance — the same company behind Daxxify — and represents a meaningful step forward in how filler is formulated. Rather than focusing purely on structure or volume, the RHA collection was built around one specific question: what happens to filler when your face moves?

The result is PRESERVED Network technology — a gentle manufacturing process that keeps the hyaluronic acid in a state closer to what naturally exists in your skin. Unlike more heavily processed fillers, RHA HA can stretch up to 32% and bounce back, according to manufacturer testing. It is also the first and only filler collection with FDA approval specifically for dynamic wrinkles and folds.

What Sets It Apart

Why RHA looks natural when you smile

Traditional fillers were not specifically designed with dynamic movement in mind. They may look excellent at rest but feel or appear stiff when you animate. RHA was engineered to solve that.

It flexes, then recovers

The PRESERVED Network technology allows RHA gels to deform and return to shape — meaning they move with your face during expression, not against it. Many patients describe treated areas feeling more natural in motion compared to other fillers they've tried.

Looks natural when you laugh

Standard fillers can leave folds or ridges visible during strong facial expressions. Because RHA moves with the tissue around it, many patients see a smoother, more integrated result when they're animated — smiling, talking, or laughing.

A distinct FDA designation

The FDA's approval of RHA specifically for dynamic wrinkles and folds is a meaningful distinction. It reflects clinical evidence that the product performs well in areas of the face under constant movement — not just at rest.

Closer to natural HA

The gentler manufacturing process in PRESERVED Network technology preserves the long-chain HA structure more than heavily cross-linked alternatives. The result is a product that may integrate more naturally with surrounding tissue, though individual results always vary.

The Products

RHA 2, RHA 3 & RHA 4

The three formulas in the RHA collection are distinguished primarily by viscosity — how thick and dense the gel is. Lighter products are for fine correction; thicker products provide structural support. Your provider will recommend the right formula — or combination of formulas — based on your anatomy and goals.

Lightest viscosity

RHA 2

Subtle correction & lip enhancement

Best for

  • Lip enhancement — natural volume and definition
  • Fine lines and moderate facial wrinkles
  • Under-eye area (periorbital lines)
  • Patients new to filler wanting a barely-there result

Because it's the softest in the collection, RHA 2 integrates beautifully for patients who want a refreshed appearance without obvious volume. It's a favorite for natural lip work.

Duration

Up to 15 months

Most Popular

Medium viscosity

RHA 3

The workhorse — lines, folds & cheeks

Best for

  • Nasolabial folds (smile lines)
  • Marionette lines
  • Cheek enhancement and mid-face support
  • Moderate to severe dynamic wrinkles

RHA 3 is the most versatile in the collection — appropriate for the majority of patients treating moderate to severe lines. Its medium body provides noticeable correction while still moving naturally with your expressions.

Duration

Up to 15 months

Thickest viscosity

RHA 4

Volume restoration & structural support

Best for

  • Significant cheek volume loss
  • Chin projection and jawline definition
  • Severe nasolabial folds
  • Patients needing meaningful structural lift

RHA 4 brings the structural strength needed for deeper restoration without sacrificing the flexibility the RHA collection is known for. Many patients are surprised by how natural it looks even at higher volumes.

Duration

Up to 15 months

Pricing shown is per syringe. Most treatments require one to two syringes depending on area and degree of correction. Final pricing is confirmed by your provider before treatment. Results and duration vary by individual.

Treatment Experience

What to expect during your RHA appointment

01

Consultation and assessment

Your provider will assess your facial anatomy, movement patterns, and areas of concern. They'll recommend which RHA formula — or combination of formulas — best suits your goals and anatomy.

02

Comfort preparation

Topical numbing cream may be applied for 15 to 20 minutes before treatment. RHA fillers also contain lidocaine, which further improves comfort during injection. Most patients find the experience manageable.

03

Treatment

Filler appointments typically take 30 to 60 minutes depending on the number of areas. Your provider will inject carefully, then gently mold the product. You'll be able to see initial results immediately, though some swelling is normal.

04

Recovery and integration

Some swelling and mild tenderness is normal for 24 to 72 hours. RHA is uniquely suited to gentle facial movement during recovery — light, normal expression may actually help the product integrate. Avoid strenuous exercise and significant heat for 24 hours.

05

Final results

RHA results are visible immediately but look their best once swelling fully resolves, typically one to two weeks post-treatment. A follow-up appointment is included to assess your results and address any questions.

06

Maintenance

Many patients see results lasting up to 15 months, though individual results vary. Your provider will recommend a maintenance schedule based on how your body metabolizes the product over time.

FAQs

RHA filler questions, answered

RHA stands for Resilient Hyaluronic Acid. It's a filler collection made by Revance (the same company behind Daxxify) and is notable for PRESERVED Network technology, which keeps the hyaluronic acid closer to its natural state. The collection is designed specifically for dynamic facial areas — parts of your face that move a lot — so filler moves naturally with your expressions instead of looking rigid.
