Frequently Asked Questions About Rha

What is RHA and how is it different from other dermal fillers?

RHA (Resilient Hyaluronic Acid) is a family of hyaluronic acid (HA) dermal fillers designed to treat dynamic facial wrinkles and folds—lines that appear with movement, like smiling or frowning. Unlike many traditional HA fillers, RHA gels are manufactured with a gentler, patented process that preserves longer HA chains, resulting in a more “resilient” gel that moves with your facial expressions rather than against them (RHA technology overview; Revance RHA collection information).

Because of this design, RHA fillers can provide natural-looking volume and smoothing both at rest and in motion, which is why they’re often chosen for areas of the face that are highly expressive.

What are the common treatment areas for RHA?

RHA fillers are versatile and can be used in many areas of the face where volume loss, wrinkles, or folds are a concern. Common treatment areas include:

• Nasolabial folds (smile lines running from the nose to the corners of the mouth)
• Marionette lines (lines running from the corners of the mouth toward the chin)
• Perioral lines (fine “smoker’s lines” around the lips)
• Lips (for subtle volume and definition)
• Cheeks and midface (to restore contour and lift)
• Corners of the mouth (to soften a downturned appearance)
• Chin and jawline (for contour and structure, depending on the specific RHA product)

Different formulations within the RHA collection (such as RHA 2, 3, and 4 in the U.S.) are tailored for different depths and severities of wrinkles and folds (product indications summary).

How does RHA work once it’s injected?

RHA fillers use crosslinked hyaluronic acid—a sugar molecule that naturally occurs in the skin and helps maintain hydration and volume. The RHA gel is injected into specific layers of the skin or deeper tissues using a fine needle or cannula. Once placed, the gel:

• Physically fills wrinkles, folds, or hollow areas
• Binds water, helping to hydrate and plump the tissue
• Integrates into surrounding tissue so it can move with facial expressions

The “resilient” quality of RHA comes from its unique crosslinking and manufacturing process, which preserves more of the HA’s natural structure and elasticity, allowing it to better adapt to dynamic facial movement (RHA technology description).

How long do RHA fillers last?

In clinical studies, RHA fillers have demonstrated results lasting up to 12–15 months in areas such as nasolabial folds, with some patients maintaining visible improvement beyond one year (pivotal RHA clinical trial data). Longevity varies based on:

• The specific RHA product used
• Treatment area (high-motion areas may metabolize filler faster)
• Your metabolism, lifestyle, and skincare habits
• The amount of product injected

Most patients schedule maintenance treatments about once a year, but your injector may recommend a personalized schedule.

Who can administer RHA in San Jose?

Regulations can vary by region, but in most of the United States, RHA fillers must be prescribed and administered under the supervision of a licensed medical professional. In San Jose, RHA injections are typically performed by:

• Board-certified dermatologists or plastic surgeons
• Other licensed physicians with aesthetic training
• Physician assistants (PAs) and nurse practitioners (NPs) working under appropriate physician oversight
• In some states, registered nurses (RNs) with specialized training, under a physician’s supervision

The U.S. FDA requires that dermal fillers, including the RHA collection, be used only by licensed healthcare providers who are knowledgeable about facial anatomy, indications, contraindications, and injection techniques (FDA dermal filler guidance). When choosing a provider in San Jose, look for:

• Current professional license in good standing
• Formal training and experience in injectable fillers
• Access to emergency protocols and products (e.g., hyaluronidase) for managing complications

Always ask to see before-and-after photos of their own patients and confirm that they regularly perform RHA or other HA filler injections.

What happens during an RHA treatment session?

A typical RHA appointment includes:

1. Consultation and assessment
   Your provider reviews your medical history, examines your facial anatomy, and discusses goals and expectations.

2. Photography and planning
   Photos may be taken for documentation. The injector maps out injection points based on your unique features.

3. Cleansing and numbing
   The skin is cleansed, and a topical anesthetic may be applied. Many RHA products also contain lidocaine for added comfort.

4. Injection
   Using a fine needle or cannula, the provider injects small amounts of filler into targeted areas. You may feel mild pressure or a pinching sensation.

5. Shaping and massage
   The provider gently molds the filler to ensure smooth, natural contours.

6. Aftercare instructions
   You’ll receive guidance on what to do—and avoid—after treatment.

Most sessions take 15–45 minutes, depending on the number of areas treated.

What are the potential side effects and risks of RHA fillers?

RHA fillers share similar side effects and risks with other hyaluronic acid fillers. Common, usually mild and temporary effects include:

• Redness
• Swelling
• Tenderness
• Bruising
• Itching or firmness at the injection site

These effects typically resolve within a few days to a week (FDA dermal filler safety information). Less common but more serious risks can include:

• Vascular occlusion (filler inadvertently injected into a blood vessel), which can compromise blood flow
• Skin necrosis (tissue damage) if vascular occlusion is not treated promptly
• Infection
• Nodules or lumps
• Allergic or inflammatory reactions

Because RHA is hyaluronic acid–based, it can be dissolved with hyaluronidase if necessary, which is an important safety advantage compared with some non-HA fillers (hyaluronic acid filler complication management review). Choosing an experienced, medically qualified injector significantly reduces risk.

How should I prepare for an RHA treatment?

Your provider will give personalized instructions, but common recommendations include:

• Avoid blood-thinning medications and supplements (such as aspirin, ibuprofen, fish oil, high-dose vitamin E, and some herbal supplements) for 5–7 days before treatment, if approved by your prescribing physician, to reduce bruising.
• Limit alcohol for 24 hours before treatment.
• Pause certain skincare products such as retinoids or exfoliating acids near the treatment area for a few days to minimize irritation.
• Inform your provider if you:
  • Are pregnant, breastfeeding, or planning to become pregnant
  • Have a history of severe allergies or anaphylaxis
  • Have active skin infections, cold sores, or inflammatory skin conditions in the treatment area

These precautions align with general safety guidance for dermal fillers from the American Society for Dermatologic Surgery.

What is the recovery like after RHA injections?

RHA filler treatments typically involve minimal downtime. Most people return to normal daily activities immediately, with some simple aftercare:

• Avoid strenuous exercise, saunas, and excessive heat for 24 hours
• Do not massage or press on treated areas unless instructed
• Sleep with your head elevated the first night if you have significant swelling
• Use cold compresses intermittently to reduce swelling and bruising

Mild swelling or bruising can last a few days. Final results are usually visible once swelling subsides, typically within 1–2 weeks (dermal filler aftercare recommendations).

How much do RHA fillers cost in San Jose?

The cost of RHA treatment in San Jose depends on:

• The number of syringes used
• The specific RHA product (e.g., RHA 2 vs. RHA 4)
• The experience and credentials of your injector
• The clinic’s location and overhead

Most practices price RHA fillers per syringe, and the total cost can range from one to several syringes per session, depending on your goals. Because RHA is a cosmetic treatment, it is not covered by insurance. During your consultation, your provider will give a detailed, personalized cost estimate and may discuss available payment plans.

Is RHA right for me?

You may be a good candidate for RHA fillers if you:

• Have moderate to severe facial wrinkles or folds, especially in dynamic areas
• Want natural-looking improvement that moves with facial expressions
• Are in generally good health and have realistic expectations
• Do not have active skin infections or uncontrolled autoimmune conditions

RHA is FDA-approved for adults 22 years and older for the correction of moderate to severe dynamic facial wrinkles and folds, such as nasolabial folds (FDA approval summary for RHA collection). A thorough in-person consultation with a qualified provider is the best way to determine if RHA or another filler is more appropriate for your needs.
