Skin scrubber
It is stimulating deeply sublayer of skin for 28,000 times in a sec kHz vibrating so that it can remove melanin & harm pigment cell and clean the wastes of pore and pilar cyst.
Iontophoresis
Iontophoresis is the theory that Electron is pushed against at the same pole (Like magnet moment).
Based on this principle, it injects ionized drugs into skin membrane with using the frequency of electricity.
Ultrasonic
Due to injection of ultrasound, calefaction, and cleansing, it eliminates all secretions from skin to out of body.
