Dr. Christopher Zachary on Radio Frequency Microneedling
Dr. Christopher Zachary, chair of the UC Irvine Dermatology Department, discusses the latest updates and applications for Radio Frequency (RF) micro needling procedures.
Traditional micro needling is a ten to twenty-minute office procedure wherein an instrument with tiny protruding needles is rolled over the surface of the skin to produce very small, superficial punctures. As frightening as this may initially sound, it is a virtually painless process with a host of advantages. This device, commonly referred to as a dermaroller, has a drum-shaped cylinder with rows of short fine needles attached to a handle. After multiple passes over the skin’s surface, tens of thousands of micropunctures are created that allow rapid healing of the epidermis, the outer layer of the skin.
Recently, the use of radiofrequency (RF) has been combined with micro needling, termed RF micro needling. The latter creates more injury and is more effective than micro needling by itself. The RF induces areas of damage at a specific depth in the dermis, which results in new collagen formation. For several decades, RF has been safely used in aesthetics as a method to stimulate collagen regeneration deeper in the skin than micro needling alone. This can effectively add more volume to the skin. There are numerous branded treatments in this category including Infini RF, Intensif, Intracel and Fractora.
