Like all fillers in @theRHACollection, RHA® 4 more closely resembles the natural hyaluronic acid (HA) found in skin. RHA® Preserved Network Technology produces a less-rigidly crosslinked gel designed to adapt to facial dynamics without compromising durability. RHA® 4 can provide natural volume for moderate to severe dynamic folds and deeper deficits, with results lasting up to 15 months—and now it's available in an optimized 1.2 mL syringe. Only from #RevanceAesthetics. #RHA4MORE #RHACollection #RevanceAesthetics Swipe for Important Safety Information.
