Radiofrequency (RF) microneedling is a minimally invasive cosmetic procedure that uses insulated needles to deliver radiofrequency energy into the skin to improve its appearance. The energy creates heat that stimulates the skin’s collagen production, which can help with wrinkles, scars, sagging skin, and uneven texture. RF microneedling can be treated on the face, neck, chest, hands, knees, stomach, and any other concerned areas.
