Skin needling delivers tiny micro injuries via needles at precise depths to kick start and renew collagen growth. Fractional RF is a similar, but a different treatment that utilizes both needles to puncture the skin as well as radiofrequency to create heat in the deeper layers of the skin. Fractional RF is generally a more uncomfortable treatment than traditional micro needling, although it may be more suited to those that have concerns with sagging skin. While both treatments will improve texture, acne scarring, fine lines, and wrinkles, traditional skin needling is better suited to all skin types including darker skins with less risk of post-inflammatory hyperpigmentation.
