So I know the Dermabrasion from my beautician and I know that my skin tolerates it. Property me this device angschafft because I already had from Skin Doctors creams and know that the brand is good, and because a dermabrasion to the beautician in the long run is already expensive. I have to say my skin (blemishes, zits Male) improve. The skin then feels nice and soft on, not irritated. Nevertheless, I use as described the device only once a week. I gave 4 stars because I am satisfied, however, it is not really comparable to me a proper dermabrasion to the beautician.
