Thank you for viewing. Facial device (ultrasonic + far infrared) Hosso Sonic This item was stored at home by my family, who hardly used it. I believe it's quite old. There is some yellowing due to aging. There is no box or instruction manual, so I don't know the details. I turned on the power and each lamp lit up. I am not familiar with this product, so please forgive any oversights. Please understand that this is a used item and consider purchasing it. ※ I researched the same product and found the following description: Beverly Corporation high-end facial device Ultrasonic & Far Infrared Press the power button, select HIGH or LOW on the menu switch, apply gel to the mirror surface of the handheld part, and slide it over the skin along the lymphatic flow on the areas of concern.
