What Are RHA® Fillers?

RHA® (Resilient Hyaluronic Acid) fillers are a next-generation collection of FDA-approved hyaluronic acid dermal fillers designed to restore youthful volume and smooth dynamic facial wrinkles and folds. Unlike traditional fillers, RHA® is uniquely formulated to move with your face — producing results that look natural both at rest and in motion.

How RHA® Works

Our skin naturally contains hyaluronic acid (HA), a substance that attracts moisture, maintains elasticity, and supports structure. Over time, HA levels diminish, leading to lines, folds, and volume loss. RHA® uses a patented gentle manufacturing process that preserves the natural structure of HA, creating a flexible gel that integrates seamlessly with dynamic facial movements.

Once injected by a skilled provider, RHA® fillers:
Bind to water to hydrate and plump the skin
Smooth wrinkles and restore lost volume
Adapt to facial expressions for a natural look and feel
Provide long-lasting enhancement with minimal stiffness

The RHA® Collection & Treatment Areas

The RHA® Collection includes a range of formulations tailored for specific goals:

RHA Redensity® – Smooths delicate dynamic lines around the mouth (perioral rhytids).
RHA® 2 – Ideal for milder dynamic wrinkles and expression lines.
RHA® 3 – Addresses moderate to deeper facial folds, including nasolabial lines; also used for lip enhancement.
RHA® 4 – Provides volumization and contouring for deeper folds, cheeks, and structural areas.

These fillers can target common concerns such as:

Nasolabial folds (smile lines)
Marionette lines
Lip augmentation
Mid-face volume loss
Fine lines around the mouth and eyes

Benefits of RHA® Fillers

Patients choose RHA® for its:

Dynamic, natural-looking results — adapts with facial expressions.
Soft, supple feel that avoids stiffness.
Hydration and improved elasticity due to HA’s moisture-binding properties.
Longer-lasting effects — many patients enjoy results for months before touch-ups.

What to Expect

RHA® treatments are performed in-office by a trained injector. After carefully choosing the right RHA® product for your goals, your provider will administer treatment with ultrafine needles or cannulas. Most patients see immediate improvement, with minimal recovery time. Downtime is usually short, with mild redness, swelling, or tenderness resolving quickly.

Safe, Personalized Care

As with all injectable treatments, RHA® fillers should be administered by an experienced medical professional. During your consultation, we’ll discuss your aesthetic goals, treatment plan, and address any questions about safety, aftercare, and expected outcomes.
