Platelet-rich plasma (PRP) is a component of blood containing growth factors and proteins that promote healing and strengthen cells. By injecting it into targeted areas of the face, neck, chest, or hands, PRP can be used to combat premature skin aging. It can boost collagen production, improve blood circulation, and repair damaged tissue. In addition, PRP can also be combined with another popular anti-aging treatment such as microneedling, chemical peels, hyaluronic acid dermal fillers, or laser resurfacing treatments to enhance its effects.
