Handpiece
The handpiece is the part of a HIFU device that’s held against the skin during treatment, housing the cartridge and making direct contact through which the ultrasound energy is delivered. Design matters here more than it might seem: an ergonomic, well-balanced handpiece makes it easier to maintain firm, even contact against the skin (important for consistent energy transfer) and to manoeuvre around smaller or curved areas like the eyes, nose, and jawline without strain. ULTRAISER’s home devices are built as a single, lightweight, cordless handpiece — the P1 and P1 Pro both weigh around 260g and are roughly the size and shape of an electric razor — designed so a first-time user can hold and guide the device confidently without clinical training. The clinic-only eHM15 uses a separate, lighter handpiece (around 130g) connected to a controller unit, reflecting its use by trained operators across longer sessions.
