Rejuvapen uses tiny needles to penetrate the skin. The sleek design allows your provider to control the speed and depth. Thousands of micro-perforations are created on the skin. As a result, the skin shifts its natural repair mechanism into high gear and starts producing collagen and elastin to repair these micro-perforations. This self-repairing property of the skin is a 100% natural form of skin renewal from the inside out. Rejuvapen’s advantage over other treatments is that it not only activates cell regeneration, it also enhances the absorption of topicals into the skin.
