RF Micro Needling Machine Often referred to as a non-surgical face-lift, Fractional RF Microneedling is a safe and minimally invasive energy based procedure.It combines microneedling & radio frequency (RF) technologies to penetrate the skin at a precise depth with tiny needles, before releasing a burst of radio frequency energy (heat). This action stimulates your skin to begin healing and thus collagen, elastin and hyaluronic acid production are also encouraged.
