The World's First FDA- Approved Pulsed Wave and Continuous Wave Radio Frequency Microneedling System. Sylfirm X delivers RF energy to the targeted into the tissue. Precise thermal coagulation is created by using evenly-leveled electrodes to penetrate the accurate target depth, in order to induce optimal results with extra effectiveness. It can reach 300-micron depth, which is capable of treating three layers at the same time. Following the treatment, exosomes are applied which are responsible for cell-to-cell communication and for facilitating the exchange of RNA (ribonucleic acid) and other important proteins between cells. They can be used to increase skin collagen and elastin.
