What is RHA? RHA, or Resilient Hyaluronic Acid, is a next-generation dermal filler designed to adapt to the dynamic movements of the face, providing natural-looking volume and elasticity. Unlike traditional fillers, RHA is formulated to integrate smoothly with the skin's natural tissues, allowing it to move flexibly with facial expressions. It’s often used in aesthetic treatments to soften wrinkles, restore lost volume, and enhance facial contours while maintaining a natural appearance. With its ability to mimic the skin’s natural resilience, RHA is especially effective for areas with constant movement, like around the mouth and eyes, providing long-lasting and subtle results.
