The RHA® (Resilient Hyaluronic Acid) fillers are the first resilient hyaluronic acid products designed to look natural with facial expressions. Have you ever seen someone smiling who looked like they had golf balls in their cheeks? That isn’t natural.

RHA fillers are designed to stretch with movement. There are four different fillers with each specialized for placement at different depths. RHA Redensity is the thinnest family member and can be used in the fine lines around the lips or in crow’s feet. RHA 2 and 3 are each slightly thicker and can be used in the lips or wrinkles. RHA 4 is the thickest and therefore best in deep folds and marionette lines.

How Long do RHA Fillers Last?

The results of RHA filler treatments are immediate and may last up to 1 1/2 years. The duration of results with any of the hyaluronic acid fillers depends on the areas treated, your age, the product used, and the quality of your skin.
