Radiofrequency comes to the rescue, not only tightening the skin, but also restoring contoured areas to create toned, firm, youthful-looking skin. This firming action makes RF especially well-suited for the chin, neck, and jawline. It can also be used to tighten: Sags between the nose and mouth.
How does radiofrequency tighten skin?
Like any form of energy, RF has the capacity to produce heat—and while each brand-name application uses a slightly different technology, all work by heating the skin’s deeper layers to induce new collagen and elastin production and encourage cell turnover, helping skin become firmer, thicker and more youthful-looking.
An advantage of using RF to heat tissues, as opposed to lasers (which use higher-frequency light waves), is that the lower frequency of RF can safely penetrate to a deeper level, helping to improve skin tone and structure, even lifting tissues. Lasers, for the most part, work to improve the skin’s surface. Moreover, RF can safely treat more patients with different skin tones without risking permanent depigmentation.
Of course, the safety and efficiency of non-surgical RF or any treatment depends on the experience and skill of the person providing that treatment (more on that later).
Is radiofrequency safe? Here’s what studies show.
We’re all exposed to low levels of human-made RF every day, from cell phones, TV, WiFi, etc. Because it’s used for so many things, radiofrequency has been extensively studied for its impact on human health. According to the FDA, the World Health Organization has classified RF radiation as “possibly carcinogenic to humans”—right along with coffee, power lines, and body powder. However, there is no conclusive evidence that RF exposure increases cancer risk in humans, even in people regularly exposed to higher amounts of RF for their jobs.
Both the American Cancer Society and Federal Communications Commission have issued extensive reports on possible impact of radiofrequency exposure. According to the FCC: “While some experimental data have suggested a possible link between exposure and tumor formation in animals [male rats] exposed under certain specific conditions [9 hours of daily exposure], the results have not been independently replicated. Many other studies have failed to find evidence for a link to cancer or any related condition.”
The main known risk associated with RF is the potential for burning from the hyperthermic effect for people exposed to high doses—for instance, those who work around radar equipment without proper protection.
Radiofrequency in FDA-cleared non-surgical tissue tightening is highly controlled for your safety.
Radiofrequency (RF) therapy, also called radiofrequency skin tightening, is a nonsurgical method of tightening your skin.
The procedure involves using energy waves to heat the deep layer of your skin known as your dermis. This heat stimulates the production of collagen.
As you age, your cells produce less collagen, which leads to sagging and wrinkles. Skin laxity occurs around age 35 to 40 when the quantity and quality of your collagen begins to decline.
RF therapy has been used since 2001 to fight against sagging skin and signs of aging. In this article, we’re going to look at how this cosmetic therapy works and what potential benefits it has for your skin.
Some of the most common types of systems in the United States and BAJA include:
RF waves heat the deep layer of your skin to between 122 and 167°F (50–75°C).
What are radiofrequency waves?
RF waves are a form of radiation. Radiation is the release of energy in the form of electromagnetic waves.
It can be classified as low energy or high energy depending on the amount of energy released. X-rays and gamma rays are examples of high energy radiation while RF waves are considered low energy.
The primary benefits of RF therapy are tightening your skin and getting rid of wrinkles.
However, RF therapy may also help fight sun damage due to its ability stimulate the production of collagen.
Fighting sun damage
Exposure to ultraviolet (UV) rays can cause the collagen fibers in your skin to break down and become disorganized.
RF therapy may help tighten loose skin on your body by stimulating the production of collagen.
One small study Trusted Source looked at the effect of RF combined with pulsed electromagnetic treatment for 8 weeks.
