SERF (세르프)
A monopolar RF lifting device that simultaneously uses dual frequencies (6.78MHz + 2MHz). It features multi-layered three-dimensional energy delivery from the epidermis to the deep dermis. Designed to reduce the risk of burns and unexpected pain through real-time skin impedance measurement and output synchronization. Clinically reported to have lower pain burden compared to existing monopolar RF (such as Thermage), allowing many cases to be treated without separate anesthesia.

Frequently asked questions
Things you may want to know before your treatment
HIFEM strongly contracts muscles to build muscle, and the energy metabolism reduces fat.
It helps under-eye fat, double chin, enlarged pores, recurring acne, and reduced firmness, tailored by area and depth.
It depends on your sagging stage, skin thickness, and budget. The stimulation depth increases in the order of superficial RF (InMode, Onda) → dermal RF (Thermage FLX, Eravi) → fascia HIFU (Ulthera, Tenssarma) → thread lifting. After diagnosis, we will determine the first step together.
