WHAT IS THE RHA® COLLECTION?
The RHA® Collection is a line of resilient hyaluronic acid dermal fillers designed to adapt to facial movement. Unlike traditional fillers that are formulated for volume or lift alone, RHA fillers are specifically engineered to treat dynamic wrinkles and folds — those that appear in areas of frequent facial motion, such as around the mouth and cheeks.
RHA stands for Resilient Hyaluronic Acid, and it was developed in Switzerland using a unique manufacturing process that preserves the natural structure of hyaluronic acid more than other fillers. This results in a flexible, longer-chain filler that moves more naturally with facial expressions.
The RHA Collection includes RHA 2, RHA 3, and RHA 4, each designed for different depths and areas of the face. These products are FDA-approved and designed to provide natural, dynamic results that hold up during everyday motion — smiling, laughing, speaking, and more.
RHA 2
RHA 2 is the lightest of the collection. It’s designed for moderate lines and finer areas of the face where subtlety and movement matter most. It’s ideal for patients who want natural enhancement and soft correction without looking “done.”
- Smooths fine to moderate dynamic wrinkles
- Treats smile lines and perioral wrinkles
- Restores hydration and elasticity to areas with light volume loss
- Ideal for facial areas with high movement
Results typically last up to 12 months and maintain their softness even during expression.
RHA 3
RHA 3 is slightly thicker than RHA 2 and designed for moderate to deep facial lines. It offers more structure while still allowing for facial flexibility. RHA 3 is often used in areas where both movement and support are needed, such as the nasolabial folds and corners of the mouth.
- Treats moderate to deep dynamic wrinkles and folds
- Fills nasolabial folds, marionette lines, and lower face contours
- Maintains flexibility in expressive areas
- Provides structure without stiffness
RHA 3 lasts up to 15 months in most patients.
RHA 4
RHA 4 is the most robust filler in the collection. It’s designed for deeper volume correction and contouring in areas where facial movement still plays a role — like the cheeks, jawline, or outer face. It adds volume while maintaining a smooth, natural look even when you smile or speak.
- Restores volume in the cheeks and mid-face
- Defines jawline and contour in dynamic areas
- Treats deeper facial folds and hollows
- Blends well into the surrounding tissue for natural results
RHA 4 can last up to 15 months and is well suited for patients needing lift and definition without stiffness.
AREAS COMMONLY TREATED WITH THE RHA COLLECTION
- Smile lines and nasolabial folds (RHA 2, RHA 3)
- Marionette lines (RHA 3)
- Chin wrinkles and oral commissures (RHA 3)
- Cheeks and mid-face volume (RHA 4)
- Jawline contouring (RHA 4)
- Fine lines around the mouth (RHA 2)
PREPARATION BEFORE TREATMENT
To reduce the risk of bruising or swelling:
- Avoid aspirin, ibuprofen, and NSAIDs 7–10 days prior
- Pause blood-thinning supplements like vitamin E, fish oil, or turmeric
- Limit alcohol for 24 hours before your appointment
- Let us know if you’ve had recent cold sores or are prone to them
WHAT TO EXPECT DURING TREATMENT
Treatment begins with a consultation and facial assessment to determine which product is right for your goals. Topical numbing cream or ice is used to increase comfort, and each RHA product contains lidocaine to further reduce discomfort.
The procedure usually takes 30–60 minutes depending on the treatment areas.
WHAT TO EXPECT AFTER TREATMENT
- Some swelling, redness, or tenderness is normal and fades within a few days
- Bruising is possible, particularly around the mouth or chin
- Avoid rubbing or massaging the treated areas unless instructed
- Refrain from strenuous exercise and alcohol for 24 hours
- Makeup can be applied after 15–30 minutes if needed
You’ll see improvement right away, but full results become more visible as swelling resolves over the next few days.
HOW LONG DOES RHA LAST?
Each product in the RHA Collection has a slightly different lifespan depending on the formulation and treatment area:
- RHA 2: Up to 12 months
- RHA 3: Up to 15 months
- RHA 4: Up to 15 months
All three products are designed to maintain natural facial movement while delivering long-lasting results.
WHEN CAN I EXPECT TO SEE RESULTS?
Results from the RHA Collection are visible immediately after treatment. You’ll see improved volume, smoother contours, and softer lines right away. Some minor swelling may occur, so the final outcome becomes more noticeable as that resolves — typically within 24 to 72 hours.
Because RHA fillers are designed to integrate naturally into dynamic areas, results continue to improve subtly as the filler settles. Full results are generally visible within one week.
WHAT ARE THE BENEFITS OF THE RHA COLLECTION OVER OTHER FILLERS?
The RHA Collection is unique in its formulation and intended use. Unlike most hyaluronic acid fillers that are designed for static wrinkles or general volume, RHA fillers are specifically made for dynamic facial areas — regions that move constantly during expression, such as the mouth, cheeks, and jawline.
Here’s how the RHA Collection stands out:
- Formulated with Resilient Hyaluronic Acid for better movement with facial expressions
- Manufactured with fewer chemical modifications, preserving the natural structure of hyaluronic acid
- Maintains softness and integration even in high-mobility areas
- Backed by clinical data and FDA approval for dynamic wrinkles and folds
- Excellent choice for patients who want subtle, expressive, natural-looking results
PROACTIVE MAINTENANCE
As with all hyaluronic acid fillers, results will gradually fade as your body metabolizes the product. Maintenance treatments every 9 to 15 months help preserve results and support long-term collagen stimulation.
Consistent treatment with the RHA Collection helps soften wrinkles, maintain facial structure, and keep your appearance youthful without looking overdone.
