Have you tried the ultrasonic beauty device, a popular item in salons and a big hit on TV, called water peeling? This product combines luxurious functions such as ultrasonic water peeling, pulse care, ion cleansing, nutrient introduction, and EMS microcurrent patting, and its greatest appeal is that it leads to smooth and supple skin. [Ultrasonic Water Peeling] Equipped with a water peeling function, a popular treatment in esthetic salons! Water peeling is a function that uses ultrasonic vibrations to turn the water on your skin into a mist, removing and cleansing dirt, sebum, and old keratin from deep within your pores. Because it uses water, it is gentle on the skin and economical as it doesn't require special gel. [Ion Extraction + Blue Light Pulse] Deep cleansing at home like a salon. The positive potential attracts and removes fine dirt and blackheads from your pores. At the same time, the blue light pulse turns on, and you can expect sterilization and acne prevention. [ION- & Red Light Pulse] The ion introduction function (ION-), which supports the penetration of ingredients that cannot be reached by hand, uses the synergistic effect of ultrasonic waves and ion introduction to allow active ingredients to penetrate and spread more quickly into the deeper layers of the skin (stratum corneum). By utilizing the electrical repulsion of ion introduction, active ingredients are introduced more effectively. The introduction power is further enhanced when performed after removing skin impurities in ion extraction (ION+ mode). Furthermore, combined with the red light pulse, whitening effects can be expected. [EMS Microcurrent] Applying a microcurrent of weak electricity flowing in a constant direction to the skin leads to skin that is full of luster and firmness. You can also expect a pleasant lifting effect. A non-contact charging base is also included, making it convenient to carry when traveling, on business trips, or overseas.
