Does the skin derma roller damage the skin?2013-07-25 22:26:57
No, there have been no reports of side effects with the Roller. The Nova Skin Roller penetrates the stratum corneum (top skin layer), where tiny needles form infiltration channels for a short space of time. The extreme slim needle-tips push the scales of the epidermis only aside, but they do not destroy them. The infiltration channels are closed in less than an hour. With shaving it's a fact that the sharp razor blades remove part of the stratum corneum but there are no reports that this centuries old procedure of shaving has any negative effect to the skin.
