How Does RHA® 4 Work?

RHA® 4 is a dynamic hyaluronic acid filler, expertly crafted to correct deeper lines and restore structure to areas of the face that experience constant movement. It’s perfect for lifting and contouring more severe facial wrinkles and folds while maintaining a natural, flexible finish. The formulation allows it to stretch and move with your expressions, making it especially effective for areas like the lower face, jawline, and cheeks.

At PRICK’D Med Spa, your treatment begins with a thorough consultation. Our aesthetic experts assess your facial anatomy, skin quality, and personal goals before creating a treatment plan tailored to you. During the procedure, RHA® 4 is injected into targeted areas using a fine needle or cannula. Most clients describe the experience as quick and tolerable.

You’ll see immediate volume restoration and lift, with continued improvement as the filler settles and hydrates the skin. Because of its resilient formula, RHA® 4 remains soft and mobile under the skin—never stiff or unnatural—making it ideal for high-movement areas that still need strong support.

A smooth experience and long-lasting results can be achieved by following the correct pre- and post-treatment instructions.

Get Fuller, Defined Cheeks with Durable, Natural-Looking RHA 4

At PRICK’D Med Spa in St. Louis, MO, we understand the importance of youthful, sculpted features. RHA 4 filler is one of the best solutions for restoring volume and contour to the face, especially in areas like the cheeks. Whether you’re looking to enhance your cheeks or restore lost volume due to aging, RHA 4 is an advanced, long-lasting filler that provides natural, subtle results.

In this article, we’ll dive into the benefits of RHA 4 filler, how it works, and why it’s an excellent choice for cheek augmentation.

What is RHA 4?

RHA 4 is a hyaluronic acid-based dermal filler specifically designed to address moderate to severe volume loss in the face. Unlike other fillers, it is engineered for use in face areas requiring more substantial volume restoration, such as the cheeks. This filler is highly durable and designed to blend seamlessly with the skin’s natural contours, providing a lifted and youthful appearance.

Ideal for those looking for long-lasting, natural cheek enhancement, RHA 4 can help define and contour the cheeks while maintaining facial expressiveness and movement.

RHA 4 Filler Treatment Areas

RHA 4 is FDA-approved and specifically formulated for dynamic areas of the face that experience frequent movement. It works beautifully in areas requiring structure, lift, and volume:

  • Cheeks – Adds volume and contour, creating a lifted, youthful mid-face.
  • Nasolabial Folds (Smile Lines) – Softens the deep lines running from the nose to the corners of the mouth.
  • Jawline – Enhances jawline definition and structure with natural-looking support.
  • Chin – Improves chin projection and balances facial proportions.
  • Lower Face Hollows – Smooths sunken or shadowed areas for a more even facial appearance.

These areas benefit from RHA 4’s elasticity and resilience, offering subtle yet substantial improvements while preserving facial movement.

How Does RHA 4 Filler Work?

RHA 4 filler replenishes lost volume in the cheeks, which naturally diminishes as we age. The hyaluronic acid in RHA 4 binds to water molecules, helping to restore volume and shape to the treated area and improving the overall contour of the face. It also stimulates the skin’s natural collagen production, resulting in a more youthful, smooth appearance over time.

The RHA 4 filler treatment process:

  • Consultation – During your consultation at PRICK’D Med Spa, your aesthetic goals will be discussed, and we will determine if RHA 4 is the best filler for you. We’ll assess your cheeks and facial structure to ensure a customized treatment plan.
  • Treatment – The RHA 4 filler is injected into the targeted areas of the cheeks. This is a minimally invasive procedure, with most sessions taking around 30 minutes.
  • Post-Treatment Care – There’s minimal downtime associated with RHA 4 filler, and you can return to most normal activities immediately. You may experience mild swelling or bruising, which usually resolves within a few days.

Who is a Good Candidate for RHA 4 Filler?

RHA 4 filler is an ideal solution for individuals seeking natural facial enhancement without surgery. You may be a good candidate if:

  • You experience moderate to severe volume loss in the cheeks or lower face.
  • You want to restore definition in areas like the jawline or chin.
  • You desire soft, natural results that preserve facial expressions.
  • You are in good overall health and not currently pregnant or breastfeeding.
  • You prefer non-surgical facial rejuvenation options.
  • You have realistic expectations and are seeking long-lasting improvements (12–18 months).

At PRICK’D Med Spa, your aesthetic provider will assess your goals and facial structure to determine if RHA 4 is the right fit for you.

Benefits of RHA 4 Filler

  • Natural-Looking Results: RHA 4 seamlessly integrates with the skin, delivering soft, subtle enhancements without the “overfilled” look.
  • Long-Lasting Volume: Unlike other fillers, RHA 4 provides lasting results, with effects typically lasting 12–18 months.
  • Sculpted Cheeks: Whether you want to lift sagging cheeks or restore youthful fullness, RHA 4 cheeks provide a natural contour and volume restoration.
  • Collagen Boosting: As the hyaluronic acid stimulates your body’s natural collagen production, you’ll continue to see improvements in skin elasticity over time.

After Your Appointment:

  • Massage and pressure should be avoided for 24 hours.
  • Apply cold compresses if swelling occurs.
  • During the following 24 to 48 hours, refrain from strenuous exercise and heavy physical activity to avoid complications.
