The RHA® Collection is Resilient Hyaluronic Acid (HA) dermal filler designed for facial dynamics. The collection represents the latest advancement in HA technology in more than a decade. The RHA® Collection uses a gentle manufacturing process to more closely resemble the natural HA in the skin.

What’s the difference between filler and neurotoxin?

Neurotoxins or neuromodulators help reduce frown, forehead, and crow’s feet lines in the upper region of the face. Fillers add volume to help soften and smooth wrinkles and folds in the lower regions of the face.

During your appointment, our licensed providers often assess both your upper and lower face when making treatment recommendations. Neurotoxin and filler treatments can be part of a full, tailored plan to help you achieve your desired results.

Why is dynamic filler important?

Areas treated by HA fillers can go back to their original shape after being altered, stretched, bent, or compressed. Fillers need to have a high level of resilience because they are used in dynamic areas of the face, such as around the mouth. With all of the micromovements we make throughout the day like smiling, laughing, and talking, it’s important to have a dynamic filler that can adapt and be resilient to the movements in the face. The RHA® Collection is specifically designed for facial dynamics and a natural look at rest and in motion.

When will I see results and how long will they last?

Dermal filler injection results are immediate. The results from the RHA® Collection of fillers can typically last up to 15 months in wrinkles and folds and 1 year in lipstick lines. 

The RHA® Collection is widely studied. The clinical effectiveness and safety of RHA® 2, RHA® 3, and RHA® 4 were shown in two 15-month studies for wrinkles and folds. The clinical effectiveness and safety of RHA® 3 in the lips was shown in a 12-month study in which nearly 1/2 of participants had increased lip fullness at 1 year. The clinical effectiveness and safety of RHA Redensity™ were shown in a 12-month study for lipstick lines—in which 2/3 of participants still had lipstick-line improvement at 12 months.
