The Rejuvapen Automatic Therapy System creates an invisible, vertical, micro perforation into the epidermis and the top layer of the dermis. As a result, the skin shifts its natural repair mechanism into high gear and starts producing collagen and elastin to repair these micro-perforations. The self-repairing property of the skin is a 100% natural form of skin renewal from the inside out. This treatment allows your skin to become firmer and regain its elasticity. Fine lines and wrinkles are reduced, pores become finer, circulation is stimulated and the overall condition of the skin improves. Rejuvapen treats fine lines and wrinkles, acne scarring, surgical scarring, burns, stretch marks, and firms and tightens most body areas.
