Microneedling creates thousands of tiny injuries in the skin's surface. Like some lasers, it’s a form of fractional treatment, which means only a fraction of the skin’s surface is affected. The undamaged skin helps in the healing process of the damaged skin. This allows for rapid healing and a short recovery time. Microneedling also allows serums like platelet-rich plasma (PRP) to penetrate dramatically better and work more effectively, by creating channels for topical products to be absorbed. Plasma is a component of your blood that contains special ‘factors’, or proteins, that help your blood to clot. It also contains proteins that promote cell growth. Injecting PRP into damaged tissues will stimulate your body to grow new, healthy cells and promote healing, thus reducing scars.
