How long do RHA Collection results last?
Clinical studies showed effectiveness for up to 15 months in dynamic nasolabial folds. For dynamic lipstick lines treated with RHA Redensity, roughly two-thirds of patients still saw noticeable results at one year.
What are the risks of RHA fillers?
Common side effects include firmness, redness, tenderness, swelling, and bruising, most of which resolve within 14 days. Rare but serious risks include vascular complications, which is why treatment should only be performed by trained medical professionals.
Can I combine different RHA formulations in one visit?
Yes. Many patients combine two or more RHA products, such as RHA 3 for lips and RHA Dynamic Volume for midface support, to address multiple concerns in a single treatment plan.
What is the difference between RHA and other hyaluronic acid fillers?
RHA products are engineered for greater dynamic strength and stretch than many traditional HA fillers, intended to help the gel hold its shape while still moving naturally with facial expression.
