The U.S. Food and Drug Administration (FDA) has issued a warning to the public about risks associated with using radiofrequency (RF) microneedling devices after several reported cases in the US on 15 October 2025. Radiofrequency (RF) Microneedling treatments are gaining popularity worldwide for tightening and smoothing skin, and treating acne scars.
What is RF?
Radiofrequency (RF) energy is a form of electrical energy that generates heat within tissues. In RF microneedling, this energy is delivered through a grid of very fine electrodes—tiny, needle-like microneedles. As these microneedles enter the skin, they deliver RF energy to controlled depths beneath the surface. Each one produces a concentrated zone of heat at its tip, triggering targeted tissue changes.
Concerns & Warnings
Several people have reported adverse effects from uses of such devices, including skin damage such as burns, disfiguring, scarring, and, in some cases, nerve damage. To treat such injuries often requires surgical or medical treatments. In its warning, FDA requested healthcare providers and the public to keep abreast of the latest updated medical information so they can make informed decisions with regards to these products.
In addition, the FDA is evaluating the manufacturers responsible for these devices to determine if the harmful effects are a mechanical issue, and is working towards resolving it. The FDA is currently monitoring the situation and has requested the public to submit reports to better assess the risk factors arising from these medical devices.
Dr. Rady Rahban, a Beverly Hills Board Certified Plastic Surgeon, stated on his Instagram that the recent warning reflects a darker aspect of medicine, where medical devices and cosmetic treatments are advertised to the public as part of a trend, without first understanding the consequences or risks involved. He urged the public to prioritise safety over trends.
