By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to noninvasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.

It is a technique for which research is ongoing, but has been used for a number of skin problems including scarring and acne. [1] Some studies have also shown that when combined with minoxidil treatment, microneedling is able to treat hair loss more effectively than minoxidil treatment alone. [2]
Microneedles (MNs) are medical tools used for microneedling, primarily in drug delivery, disease diagnosis, and collagen induction therapy. Known for their minimally invasive and precise nature, MNs consist of arrays of micro-sized needles ranging from 25μm to 2000μm.
The difference between microneedling and RF microneedling, plus side effects, benefits and different brands of RF microneedling devices. Why Radiofrequency Microneedling Is Becoming So Popular ...
Potential problems with the measurement devices have been known for decades. The FDA began to develop guidance for manufacturers to address the issues in 2013, but little has been done since.
Radio frequency (RF) energy at power density levels of 1–10 mW/cm 2 or higher can cause measurable heating of tissues. Typical RF energy levels encountered by the general public are well below the level needed to cause significant heating, but certain workplace environments near high power RF sources may exceed safe exposure limits.
