The Ultrasonic Beauty 3 MHz ultrasound massager is a combination of light therapy, ion lead-out and 3 MHz ultrasound frequency. Quasi an all-in-one-care system that is very easy to use. Panel is clear and understandable, but also a manual (in German) is. I use the device now for almost a month. I ordered it because I wanted to alleviate the one my pigmentation on the cheeks, on the other first lines under the eye and the mouth. I start after a thorough facial cleansing with the ion lead-out (negative ion and positive ion each about 3 minutes). When cleansing I notice a slight tingling sensation on the skin. Then I switch to ultrasound treatment (with hyaluronic gel) to coincide with the light therapy. This takes about 10 minutes. Green light is to soothe the skin to lighten it and to reduce dark circles. Red light to activate the cells to produce more collagen, counteracting quasi skin aging. There is Blaulich for acne-ridden skin, but I do not use. Depending on your mood, I do not begrudge me afterwards still for a minute, a vibration massage, and then apply the usual night care. What I definitely can say: My pigmentation have become paler, the skin appears lighter overall. Pimples and redness on the cheeks have declined. To minimize lines and wrinkles, I can not say yet, however. For that I have to wait a longer time probably. I recommend the device further definitely. Wonder you certainly can not expect, but for a more harmonious complexion it has at least taken care of me.
