ESTHE TWIN Facial Device F300 This is a handheld beauty device with three functions: ultrasonic waves, far-infrared rays, and negative ions. It achieves lymphatic treatment, which is said to be difficult with hand massage alone, and addresses various skin concerns such as wrinkles, spots, dullness, and sagging. I purchased it for about 100,000 yen at an esthetic salon I used to go to. It was about 10 years ago, but I think it's in good condition. *There is a small scratch on the second image. There are no instructions or dedicated gel.
