The RHA® Collection — Resilient Hyaluronic Acid — is the only FDA-approved family of dermal fillers designed specifically to treat dynamic wrinkles, the lines that appear when you smile, laugh, or speak. At NewSkin Laser Center in Northridge and Simi Valley, RHA is a favorite for clients who want their results to look just as natural in motion as they do at rest.
Most traditional hyaluronic acid fillers are engineered for static lines — the creases visible when your face is relaxed. RHA's manufacturing process preserves more of HA's long, natural chains, producing a gel that is both strong enough to lift and flexible enough to stretch and recoil with facial expression. The result is filler that disappears into the conversation, not into stillness.
The collection includes RHA 2, RHA 3, and RHA 4 for progressively deeper folds and wrinkles, plus RHA Redensity™ for fine perioral lines around the lips. Your injector at NewSkin matches the product to the treatment area: RHA 2 for fine lines and superficial smoothing, RHA 3 for moderate nasolabial folds and marionette lines, and RHA 4 for deeper folds and structural support.
An RHA appointment at our Southern California medical spa typically takes thirty to forty-five minutes. The product contains lidocaine for in-syringe comfort, and a topical numbing cream is applied beforehand. Results are visible immediately, refine over two weeks, and last up to fifteen months — a meaningful duration for a filler engineered for movement. Like other HA fillers, RHA is reversible with hyaluronidase if needed.
