Book a consultationWhat is Sunny
Sunny is a monopolar radiofrequency device made by Shenb in Korea. Its main handpiece uses 6.78 MHz RF to heat the dermis and deeper tissue for tightening, like other monopolar devices.
Its delivery splits each pulse into smaller ones, which is designed to reduce pain and surface stress while keeping the total heat effective. A second handpiece, Pulsar, can work in monopolar or bipolar mode at lower frequencies for different depths.
Different tips allow the face and smaller areas to be treated with the appropriate contact size.
