RHA Redensity™ is a weightless filler that smooths delicate lipstick lines. It uses a gentle manufacturing process to more closely resemble the natural HA in the skin—for clean beauty. 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.
