The fact that the organization selling this doesn't appear to release their full study doesn't inspire confidence. The summary info they release isn't enough to tell if they have any basis for their claims. They also only claim that they are FDA-approved without any details of what approval they received. Since there is no claim that is an FDA approved treatment it probably isn't which in turn means that they probably don't have any conclusive evidence that the device does anything. In this industry it's what ISN'T said that is important. If they can't claim to be an FDA-approved treatment for acne then there's probably a good reason.
