The Rejuvapen microneedling system is a device that uses microneedling to promote the production of new collagen and elastin in the skin. The device uses several tiny needles that cause micro-wounds; the body responds to this by increasing collagen production as a way to repair the skin. This results in tighter, firmer, and healthier-looking skin, with fewer facial lines and folds and an increased ability to prevent the formation of wrinkles. The collagen in the skin helps to give the skin structural support and elasticity which results in a youthful appearance and feel. Rejuvapen also promotes the production of elastin, another important skin protein that is responsible for skin tightness and wrinkle prevention.
