RF Microneedle

Effects of Energy-Based Devices on HA Filler

Heat-Based Devices and Dermal Fillers

A study using abdominoplasty skin samples revealed that the heat of fractional microneedle radiofrequency (RF) devices can cause thermal damage to hyaluronic acid (HA) fillers. For “Histologic Effects of Fractional Laser and Radiofrequency Devices on Hyaluronic Acid Filler,” published in the April issue of Dermatologic Surgery, Sarah Ham Hsu, MD, Hye Jin Chung, MD, MMS, and Robert Weiss, MD, divided abdominoplasty skin samples into eight zones. They injected HA filler intradermally into seven zones with one zone left untreated to act as control.
