Refined Rejuvenation With RHA Fillers

Your face is always in motion—smiling, laughing, speaking—and every expression is a reflection of who you are. The RHA® Collection adapts to the movements of your face, delivering results that look natural.

Dr. Monica Tadros offers the RHA® Collection to give you a modern, refined approach to facial rejuvenation. These fillers use hyaluronic acid and Swiss innovation to blend with your skin, soften lines, and restore volume, while preserving your natural expressions.

What Is the RHA® Collection?

The RHA® Collection is the first and only line of resilient hyaluronic acid (HA) fillers FDA-approved to treat dynamic facial wrinkles and folds. Developed in Switzerland with a patented manufacturing process, RHA® fillers mimic the natural HA found in your skin, so they move with your facial expressions, not against them.

What sets RHA® apart is its ability to provide a softer, more flexible result that adapts to the natural movements of your face. Whether you’re smiling, laughing, or at rest, the RHA® Collection gives you a refined, authentic appearance, without the stiffness or overfilled look of traditional fillers.

Types of RHA® Fillers

There are four formulations in the collection—RHA Redensity™, RHA® 2, RHA® 3, and RHA® 4—each tailored to address specific areas and depths of facial aging.

From fine lines around the lips to deeper folds and volume loss in the cheeks and jawline, Dr. Tadros selects the ideal formulation for your unique anatomy and aesthetic goals.

Ideal Candidates for RHA® Fillers

The RHA® Collection is ideal if you want to restore youthful volume and smooth expression lines while maintaining the natural movement and integrity of your facial expressions.

You may be a strong candidate for RHA® if you:

  • Are beginning to notice dynamic wrinkles—creases that appear during facial movement, such as smile lines or laugh lines
  • Prefer a soft, natural look that preserves facial fluidity
  • Want to treat moderate to severe facial folds, including nasolabial folds, marionette lines, or perioral wrinkles
  • Are seeking a longer-lasting filler, with results that can endure up to 15 months
  • Have previously used dermal fillers but want a more advanced, expressive option
  • Are in good health and not currently pregnant or breastfeeding

How to Prepare for Your RHA® Filler Appointment

To ensure optimal results and a smooth treatment experience, a bit of preparation can go a long way. During your consultation, Dr. Tadros will assess your medical history, skin condition, and aesthetic goals to determine the ideal RHA® formula for your needs.

To prepare for your RHA® treatment:

  • Avoid blood thinners (like aspirin, NSAIDs, or certain supplements such as fish oil and vitamin E) for about five to seven days before your appointment, unless otherwise advised.
  • Limit alcohol intake 24 hours before treatment to help reduce the risk of bruising.
  • Inform us of any active skin conditions, such as cold sores, acne, or irritation in the treatment area.
  • Arrive makeup-free to maintain cleanliness and reduce the risk of post-treatment irritation.
  • Discuss any prior filler treatments or aesthetic procedures during your consultation.

What to Expect During Treatment

Dr. Tadros performs RHA treatments in-office, which typically take 30 to 45 minutes, depending on the treatment areas and the formulation used. Dr. Tadros’s advanced injection techniques ensure results that enhance your natural beauty, without altering your expressions.

Here’s what to expect:

  • Cleansing & numbing: We'll clean the treatment area and apply a topical anesthetic for added comfort. RHA® fillers also contain lidocaine to help minimize discomfort during injection.
  • Precise injection: Using a fine needle or microcannula, Dr. Tadros will inject the RHA® filler to smooth lines, lift contours, and restore volume.
  • Assessment & finishing touches: Once injected, the area is sculpted to ensure even distribution and balanced, beautiful results.

RHA Filler Recovery
& Results

One of the key advantages of the RHA® Collection is its ability to deliver refined, natural results with minimal downtime. Because these fillers integrate with your tissue and adapt to facial movement, recovery is typically smooth, and results look and feel authentic.

Immediately After Treatment

  • Mild swelling, redness, or tenderness at the injection site is normal and typically resolves within 24 to 72 hours.
  • Bruising may occur, especially in sensitive areas, but is usually mild and can be concealed with makeup after the first day.
  • You’ll notice an immediate improvement in volume and line softening, with continued refinement as swelling subsides.

Aftercare Tips

  • Avoid intense exercise, heat exposure (like saunas), and alcohol for the first 24 hours.
  • Refrain from touching or massaging the treated area unless advised by Dr. Tadros.
  • Apply cold compresses as needed to reduce swelling.

Long-Lasting Results

  • RHA® fillers are designed to be resilient—they stretch and compress with your skin, which helps maintain a natural look in motion.
  • Depending on the formulation used and treatment area, results typically last between 12 and 15 months.
  • Follow-up appointments are available to assess your progress and determine if you want additional refinement.
