Radiofrequency Technology

Radiofrequency (RF) generates heat in tissue through high-frequency current. Its performance depends on the coordination between energy format, electrode structure and temperature control. The key engineering question for RF devices is delivering energy accurately to the target layer while keeping it controlled.

Radiofrequency device technology at LEIJEX covers microneedle, vacuum and fractional forms, with energy delivery controlled from waveform to tissue feedback.

Three RF Formats

• RF microneedling: energy delivered through micro-needles at defined dermal depths, combining fractional logic for precise heating — LEIJEX’s Gold RF Microneedling belongs to this format.
• Vacuum RF: negative pressure combined with RF heating, common in body contouring and circumferential tightening applications (e.g. the ThermTech vacuum RF series).
• Intracavitary RF: dedicated handpiece designs for specific applications such as feminine wellness and breast care.

Impedance, Temperature and Energy Control

Tissue impedance changes with temperature and hydration, directly affecting energy distribution. RF control design must monitor status in real time and adjust output to avoid localized overheating. Temperature control, pulse width and handpiece contact state are the three pillars of RF safety design.

Coordination with the Group Technology System

The RF platform is deeply coupled with the energy delivery control system: output monitoring, status feedback and operator interfaces share the same control framework — one reason LEIJEX presents platform engineering relationships at group level.
