MNRF uses radio frequency energy waves to transfer heat to collagen under the skin. The electrodes placed over the skin in the form of needles transmit RF energy waves which generate heat. As heat flows through the layers of skin with less hindrance it stimulates the production of new collagen and elastin which improves skin texture. A laser uses an intense light beam which converts into heat in the skin. It breaks and remodels the scar to heal over time.
