What is the RHA® Collection?

The RHA® Collection is Resilient Hyaluronic Acid (HA) dermal fillers 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. The RHA® Collection offers four HA-filler formulations. RHA Redensity™ is a weightless filler that smooths delicate lipstick lines. RHA® 2 and RHA® 3 offer elegant and refined smoothing for those seeking a soft, natural look in wrinkles and folds. RHA® 3 also enhances lip fullness and definition. Lastly, RHA® 4 provides natural volume for deeper dynamic wrinkles and folds.
