RHA 2 Dermal Filler Injections in St. Louis, MO
If you’ve been researching dermal fillers, you may have come across the RHA Collection. Among these innovative fillers is RHA 2, known for its natural look and dynamic flexibility.
What Is RHA 2?
RHA 2 is part of the RHA (Resilient Hyaluronic Acid) Collection of fillers designed to adapt seamlessly to the dynamic movements of the face. Unlike traditional fillers, the RHA line is formulated to closely mimic the natural hyaluronic acid found in your skin. This allows it to move with facial expressions rather than remaining stiff or rigid.
How RHA 2 Is Different?
- Resilient Formulation: It’s engineered to be more flexible, so it integrates smoothly with your facial tissues.
- Natural Appearance: Because of this resilience, many patients find that RHA 2 results in a subtler, more natural look—even when smiling, laughing, or making other facial expressions.
Who Makes RHA 2?
RHA® 2 is manufactured by TEOXANE Laboratories, a Swiss aesthetic company renowned for its innovative skincare and dermal fillers. In the United States, the RHA Collection is distributed by Revance Aesthetics, which brought the line to the U.S. market after it received FDA approval. TEOXANE’s original formulation has a longstanding reputation in Europe, and now American providers and patients can also benefit from this advanced filler technology.
What Is RHA 2 Used For?
The different fillers in the RHA line (RHA 2, RHA 3, RHA 4, and RHA Redensity) are each designed for specific indications based on how robust or flexible the filler is. RHA 2 specifically targets moderate dynamic wrinkles and folds, such as:
- Mild to moderate nasolabial folds (the lines running from the sides of the nose to the corners of the mouth)
- Perioral lines (vertical lip lines)
- Other wrinkles in areas of the face that move frequently
Because RHA 2 provides a medium level of volume and smoothness, it’s ideal for patients who want a natural correction for moderate wrinkles without looking overfilled.
Who Is a Good Candidate?
Most healthy adults seeking to address mild to moderate lines and wrinkles can be good candidates for RHA 2. The ideal candidate would be someone who:
- Has Mild to Moderate Facial Wrinkles: If you have deeper or more severe folds, a different filler (like RHA 3 or RHA 4) might be more appropriate.
- Desires a Natural Look: RHA 2’s flexibility is designed for patients who want subtle improvements that move naturally with facial expressions.
- Is in Good Overall Health: As with any cosmetic procedure, patients should be free of active infections, inflammatory skin conditions, or other contraindications in the treatment area.
- Has Realistic Expectations: While fillers can produce remarkable improvements, it’s important to have clear and realistic goals in consultation with your provider.
Side Effects
Like all injectable fillers, RHA 2 can have side effects. Generally, these are mild and may include:
- Redness at the injection site
- Swelling or slight bruising
- Tenderness or discomfort in the treated area
- Itching or minor irritation
These side effects usually subside within a few days to a week. More serious complications are rare but can include infection or vascular compromise if a blood vessel is accidentally injected.
Benefits of RHA 2
- Natural Appearance: RHA 2’s hallmark is the subtle, natural-looking result it provides.
- Flexibility with Facial Expressions: Its resilient formulation allows the product to move with your face rather than creating a stiff look.
- Long-Lasting Results: Results can last up to a year for many patients, though individual longevity can vary.
- FDA-Approved and Clinically Tested: RHA fillers are backed by clinical trials and rigorous testing.
- Versatile Treatment: While best for moderate lines, RHA 2 can be used in various facial areas for a comprehensive rejuvenation.
General Questions
- How long do the results of RHA 2 last? Most patients enjoy the benefits of RHA 2 for up to 12 months, though this can vary depending on factors like metabolism, lifestyle, and the area treated. After this period, touch-up treatments can help maintain your results.
- Is the treatment painful? RHA 2 injections contain lidocaine, which helps minimize discomfort. Additionally, your provider may use a topical numbing cream or other methods to make the procedure more comfortable.
- How soon will I see results? Results are visible immediately after treatment, though you may experience some swelling or bruising in the first few days. As any swelling subsides, you’ll see the final, natural-looking outcome.
- Can RHA 2 be combined with other treatments? Absolutely. Many patients combine dermal fillers with Botox, Dysport, lasers, or chemical peels to achieve a more comprehensive facial rejuvenation. Always consult your provider to develop a customized treatment plan that aligns with your goals and ensures your safety.
- Do I need downtime after RHA® 2 injections? There is typically minimal downtime. Most people can return to their daily activities right away, although you may want to avoid intense exercise, alcohol, or direct sunlight for at least 24 hours to minimize swelling and bruising.
- What if I have a special event coming up? It’s best to schedule your injection at least two weeks before any special event to allow any swelling or bruising to subside, ensuring you look your absolute best on the big day.
- How do I know which RHA filler is right for me? Your provider will evaluate your skin concerns, facial anatomy, and goals to determine which RHA® filler (2, 3, or 4) or combination is best for you.
Additional Tips and Considerations
- Consultation Is Key: A thorough consultation with one of The Saint Louis Med Spa’s nurse injectors will help set realistic expectations and see what injectable is right for you.
- Medical History: Always disclose any allergies, medical conditions, or medications you’re taking to avoid complications.
- Maintenance: While RHA 2 can offer lasting results, periodic touch-ups can help you maintain your refreshed look.
- Healthy Lifestyle: Good skincare, proper hydration, and a healthy diet can enhance and prolong the benefits of any filler treatment.
