Morpheus8 is microneedling with radio frequency with adjustable depth (up to 4 mm) with fine surgical pins. At the end of these fine pins, radio frequency waves are emitted. The microneedles cause a controlled injury that results in formation of new collagen and elastin (the fibers responsible for skin tightening). In addition, the radio frequency waves also stimulate collagen and elastin formation. So, you have skin rejuvenation occurring from 2 different formats.
