A truly great device for optimal pore deep facial cleansing. Probably grossly overpriced, considering how little technology is available, but the effect is really convincing. Have very sensitive skin with strong Mitesserbefall in the T-zone. After 3 times I can see a use Verbessserung. the small blackheads are gone. However, have bought the brush head for sensitive skin to because my skin dries out quickly despite oily T-zone. After clean the skin should be well creamed, as it would otherwise certainly dry out too much. But with a good rich cream that's doable. The result can really be seen, therefore the price of the device is well justified. Especially since I now save the cost of the beautician.
