The SkinPen® combines the healing and skin regrowth properties of platelet-rich plasma (PRP) and microneedling. Microneedling creates mini injuries to the skin, while PRP utilizes platelets from plasma that are very high in growth factors to send signals to the skin cells for regrowth. As the skin heals after treatment, new collagen and elastin grow fresh without the previous scar tissue, resulting in a smoother beautiful appearance.
