On October 16, the US Food and Drug Administration (FDA) warned about possible serious complications from RF microneedling. These include burns, scarring, fat loss, disfigurement and nerve damage. The agency advises against using it at home.
FDA safety communication: serious complications listed, but no case numbers
On October 16, the FDA issued a safety communication about radiofrequency microneedling (RF microneedling). The trigger and scope remain unclear: the agency names no specific devices and gives no number of people affected.
According to the FDA, reports describe “serious complications”, including burns, scarring, fat loss, disfigurement and nerve damage. In some cases, surgical correction or further medical treatment was needed. The warning concerns dermatological and aesthetic uses intended to improve the appearance of the skin.
With RF microneedling, fine microneedles enter the skin and deliver radiofrequency energy at defined depths. This creates heat that can alter tissue. Devices must go through the 510(k) process before being marketed. This is different from cosmetic microneedling; the linked treatment page describes that service and not an RF treatment.
Dermatologist Mathew Avram (Massachusetts General Hospital) said these side effects are generally known; without data, it is difficult to assess how urgent the issue is. Complications can be reported through the FDA’s MedWatch reporting system.
Putting it in context: RF microneedling remains a medical procedure
In its communication, the FDA stresses that RF microneedling should be treated as a medical procedure and is not intended for home use. This is especially relevant for studio and spa clients because RF microneedling is often perceived as a beauty treatment, even though the agency says its risks can be medically serious.
The FDA recommends having treatments performed only by licensed, trained providers and asking which device is being used. It can also help to ask the right questions during an initial consultation at a studio. Both professionals and consumers should report unusual events or complications to MedWatch.
Mathew Avram also explained that RF microneedling is generally safe and effective in “experienced hands”. At the same time, the warning shows that the use of energy-based devices in aesthetics remains under regulatory scrutiny—especially where the market also promotes at-home devices.
The FDA warning puts RF microneedling under closer safety scrutiny, while leaving details such as the number of cases open. For clients in the aesthetics industry, the focus shifts to who performs the treatment and which technology is used.
