RHA 4 Dermal Filler Injections in St. Louis, MO

In the rapidly evolving world of aesthetic medicine, new products regularly enter the market promising better, more natural-looking results. Among the most talked-about new options for facial rejuvenation is the RHA® (Resilient Hyaluronic Acid) line of fillers, with RHA 4 often highlighted for its ability to address deeper lines and folds while respecting the natural movement of your face.

What Is RHA 4?

RHA 4 is part of the RHA Collection of dermal fillers, which utilize a next-generation hyaluronic acid technology designed to mimic the natural hyaluronic acid in our skin. While traditional fillers can sometimes appear stiff or less mobile when the face is in motion, the RHA line stands out by maintaining a high degree of flexibility. RHA 4 is specifically formulated for deeper dynamic wrinkles and folds, as well as for restoring volume in areas that require more robust support, such as cheeks, nasolabial folds, and the lower face.

How Is It Different?

• Resilient Hyaluronic Acid Technology: RHA 4 is manufactured to be more adaptable to facial movements. This means it can adjust when you smile, frown, or laugh, providing a more natural look.
• Long-Lasting Effects: The unique manufacturing process also helps the filler break down more slowly, potentially leading to longer-lasting results than older-generation fillers.

Who Makes RHA 4?

The RHA® collection, including RHA 4, was developed by TEOXANE Laboratories in Switzerland, known for their expertise in hyaluronic acid research and skincare. In the United States, it is distributed by Revance Aesthetics, a company focused on innovative aesthetic solutions. This partnership ensures that the RHA® line meets both European and U.S. regulatory standards, providing reassurance about its quality and safety profile.

What Is RHA 4 Used For?

RHA 4 is formulated for moderate to severe dynamic wrinkles and folds, such as:

• Nasolabial Folds (the lines that run from the sides of your nose to the corners of your mouth)
• Marionette Lines (lines from the corners of the mouth down toward the chin)
• Cheek Volume Restoration (for sunken or flattened cheeks)
• Jawline Definition (in some cases)

Because of its robust yet flexible consistency, RHA 4 is often used in areas that experience a lot of movement but require a significant amount of support and volume.

Who Is a Good Candidate?

While a qualified medical professional should make the ultimate determination, good candidates for RHA 4 often:

• Have Deeper Wrinkles or Folds: Particularly in the mid-to-lower face areas.
• Desire Natural-Looking Results: RHA 4 is specifically designed to adapt to facial movements.
• Are in Generally Good Health: Ideal candidates do not have unaddressed health conditions that could impair healing.
• Have Realistic Expectations: As with any cosmetic procedure, it’s important to understand that “refreshed” does not mean “completely changed.”

If you have a history of severe allergies, bleeding disorders, or are pregnant or breastfeeding, discuss these factors with your provider to determine if RHA 4 is appropriate for you.

Potential Side Effects and Considerations

Like other hyaluronic acid-based dermal fillers, RHA 4 is generally well-tolerated. However, you may experience:

• Bruising and Swelling: Common around the injection site, usually resolving within a few days.
• Redness or Tenderness: Temporary and typically mild.
• Itching or Minor Discomfort: Often subsides quickly.
• Lumps or Bumps: In rare cases, or if injected superficially.
• Infection or Allergic Reaction: Extremely rare but always possible with any injectable procedure.

Benefits of RHA 4

• Natural Look and Feel: Thanks to its resilience, RHA 4 moves in harmony with your facial expressions.
• Longer-Lasting Results: Many patients find they need touch-ups less frequently compared to some traditional fillers.
• Versatility: Useful for both volume restoration and deep fold correction.
• Minimal Downtime: Most people resume normal activities shortly after their procedure.

General Questions

• How Long Do the Results Last? Results may vary, but many patients enjoy the effects of RHA 4 for up to 12–15 months, depending on individual factors such as metabolism, lifestyle, and treatment area.
• Is the Procedure Painful? A topical numbing cream or local anesthetic may be used to minimize discomfort. Most patients report only mild pressure or a pinching sensation during the injections.
• How Quickly Will I See Results? You’ll notice an immediate improvement in volume and wrinkle reduction, though minor swelling or bruising could temporarily obscure the final outcome. The final, settled look typically appears within 1–2 weeks.
• Are There Any Specific Aftercare Instructions? Avoiding strenuous exercise for 24–48 hours, using cold compresses for the first day to reduce swelling, limiting alcohol and anti-inflammatory medications to reduce bruising, sleeping with head elevated for the first night if advised.
• How Does RHA® 4 Differ From RHA® 2 or RHA® 3?
  • RHA® 2 and RHA® 3 are often used for finer lines or moderate wrinkles.
  • RHA® 4 has a thicker consistency suitable for deeper lines and areas requiring more volume.
• Is There Any Downtime? Downtime is minimal. While you might experience temporary swelling or bruising, most patients return to normal activities the same day or the following day.

RHA 4 represents a forward-thinking approach to dermal fillers, offering a resilient and flexible formula tailored for deeper, dynamic wrinkles. Its ability to integrate seamlessly with the facial movements sets it apart in delivering natural-looking results. If you’ve been considering a dermal filler that not only restores lost volume but also respects your facial expressions, RHA 4 might be the perfect option.
