The device is easy in handling, easy of use. After a few days of use, the first signs of success can be seen. The skin is firmer, plumper and fresher. Treatment with the Hyalurongel had shown that dry skin can better store moisture, they are no longer stressed and looks fresh. Weekly treatment resulted in the skin was firmer, making the deeper wrinkles have been smoothed out somewhat. I started with small steps, provided higher later gradually. The unit I am very satisfied.
