What it is
RHA (Resilient Hyaluronic Acid) fillers are FDA-approved hyaluronic-acid gels engineered to behave more like native tissue under dynamic motion. The three densities — RHA 2 (lightest), RHA 3 (medium), RHA 4 (densest) — let the clinician match product to indication.
How we approach it
RHA suits patients who want natural movement and have noticed previous fillers reading “set” during expression. The clinician chooses the density per area: RHA 2 for fine lines and lip body, RHA 3 for nasolabial folds and marionette lines, RHA 4 for deeper structural correction with motion preserved.
What to expect
Immediate volume; swelling 1–3 days; final result at two weeks. Duration up to fifteen months.
Candidacy
Best for patients in motion-rich treatment areas who value natural expression. Not for pregnant or nursing patients or those with active infection in the treatment region.
