RF Micro-needling (also known as collagen induction therapy) machine is for skin rejuvenation treatments. A device with fine needles or pins creates tiny punctures in the top layer of the skin, which triggers the body to create new collagen and elastin. Results can include improved texture and firmness, as well as skin resurfacing. The RF energy is delivered via small needles into the dermis. Because the RF energy is delivered so deeply, it can produce faster results that are more dramatic.
