I bought the ultrasound machine after I was so impressed by the treatment with ultrasound of the beautician. The result in the salon was immediately visible. The skin was immediately plumped, wrinkles were as good as gone. Unfortunately, that does not last long. But each week, the treatment would be just too expensive. Therefore the device. This also works with a MHz as in the studio. The device makes a high impression, even the screen does what forth. The settings find somewhat misleading. For dry skin, the mode (anti wrinkles) is strongest. I only use this. However, it turns out after 3 min., Which is of course much too short. I turn the mode repeatedly again and treat my face for about 15 minutes. The times should have set it longer. Commenting on the outcome, I can only say that so far I can not notice any visible changes. With a device from the studio man can unfortunately not compare. I would be interested what makes the difference. While I see immediate results in the studio, this is at home not so. Perhaps if man uses it every 2nd day and that more than 3 months ....... ?? I use it the way since about 8 weeks about 3 times a week. I do not know if I would buy it again for me. Hyaloron syringes help there definitely is more, just more expensive.
