Radiofrequency microneedles are done using a device that contains tiny needles to Pierce the skin. Radiofrequency technology is then applied deep into the dermis, and by pulling out the tips, the device creates a controlled area of damage on the skin’s surface. The body recognizes the injury even if it’s not enough to cause a scab or scar, so it activates the skin’s natural healing process. The body triggers the production of collagen and elastin, which improves skin texture and firmness and reduces scars, pore size and stretch marks.
