Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation. [2]
Known for their minimally invasive and precise nature, MNs consist of arrays of micro-sized needles ranging from 25μm to 2000μm. Although the concept of microneedling was first introduced in the 1970s, its popularity has surged due to its effectiveness in drug delivery and its cosmetic benefits.
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.

RF electrosurgery is commonly used in virtually all surgical disciplines including dermatological, gynecological, cardiac, plastic, ocular, spine, ENT, maxillofacial, orthopedic, urological, neuro- and general surgical procedures as well as certain dental procedures. RF electrosurgery is performed using a RF electrosurgical generator (also ...
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 ] Platelet-rich plasma (PRP) can be combined with collagen induction therapy treatment in a form of dermatologic autologous blood therapy .
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
US frequency allocations chart, 2016. Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1]
Plasma needling is a minimally invasive aesthetic medical procedure purported to rejuvenate skin, minimize the appearance of hypertrophic and hypotrophic scars and stretchmarks, and reduce pattern hair loss through multimodal physical and biochemical cellular stimulation. It is a combination of classical medical micro-needling by Dermaroller or ...
