I'm selling this because I'm replacing my machine and no longer use it. It doesn't have to be the dedicated gel; cavitation is possible with hair removal gel or conductive gel. I've confirmed this. I'll include some usable gel, although it's been opened. It worked well for both body and face. The operation is simple, and you can follow the instructions. You can use it on your face and body. 【Four Powerful Functions】 ▶︎Cavitation...Body Mode This treatment uses high-output 40kHz ultrasound to vibrate the skin. It targets stubborn, hardened fat and uneven skin. ▶︎Radio Frequency (RF)...Face Mode/Body Mode Adopting "Circle RF Technology," it gently and deeply warms the skin to the deep layers (stratum corneum). In Body Mode, it prepares the body for treatment, and in Face Mode, it combines with EMS and ultrasound for effective facial care. ▶︎Ultrasound...Face Mode The tapping effect of 1MHz ultrasonic vibration improves skin firmness and elasticity. When used with cosmetics, beauty ingredients are efficiently absorbed, allowing you to experience further effects. ▶︎EMS...Face Mode/Body Mode In Body Mode, it stimulates from surface muscles to inner muscles with different low and medium frequency waveforms, achieving authentic training. In Face Mode, it stimulates and trains deep facial muscles with double low and high-frequency waves, leading to a lifted, upward-facing face. ■Size: Width 36cm X Depth 26cm X Height 16cm ■Weight: 2.4kg ■Rated Power Consumption: 50W Immediate purchase is possible.

I used it for about a year, but I'm selling it because I no longer use it due to replacing my machine. The original price was close to 400,000 yen. It works without any problems. There are no accessories like gel. There is an outer box and instruction manual. There are minor scratches and stains. I will thoroughly disinfect it before shipping. Since it is a used item, returns are not accepted after purchase.
