Merz Aesthetics has secured FDA clearance for Ultherapy PRIME on knee skin laxity, extending the platform's non-surgical lifting footprint beyond the face and neck. The indication leverages PRIME's core advantage—real-time ultrasound visualization during treatment—to guide energy delivery and ensure consistent collagen remodeling in a notoriously difficult anatomical zone.
Ultherapy PRIME Clears FDA for Knee Skin Laxity
Merz expands the first real-time ultrasound platform into a new body-contouring indication.

First and only FDA-cleared ultrasound with real-time visualization for non-surgical skin lifting.
Knee laxity remains underserved in most practices. The area is prone to skin laxity post-weight loss and aging, yet few devices deliver predictable results without invasive surgery. PRIME's ability to visualize tissue depth and energy penetration in real time addresses that gap. The clearance positions Merz to capture a secondary revenue stream in body contouring without requiring new hardware investment from practices already running the system.
