The Facts On RF Skin Tightening

Radio Frequency skin tightening, also known as RF Therapy, is a powerful anti-aging treatment that firms the skin, boosts circulation, and stimulates collagen production for tighter skin and overall skin rejuvenation. 

The technique uses Radio Frequency energy to heat the skin, stimulating collagen and elastin production.

How RF Skin Tightening Works

Radio Frequency has emerged as a popular treatment option for reducing fine lines and loose skin. Its principle relies on using RF energy to heat the deeper layers of the skin for a precise amount of time to stimulate collagen and elastin production, thereby tightening the skin.

Studies have found that maintaining a temperature over 115°F (46°C) for over 3 minutes causes the body to release heat-shock proteins. These proteins stimulate the body to create new collagen fibers.

What Is Collagen?

Collagen is a common protein found in the human body, making up 80% of the skin’s texture. It creates the framework of the skin and provides firmness and strength.

Where Does The Name “Radio Frequency” Derive?

The electrical currents used for beauty treatments happen to be part of the Radio Frequency spectrum, i.e., the frequencies used for radio communications (3 kHz to 300 GHz). Hence aesthetic treatments using electric currents or electromagnetic fields of such frequency are called Radio Frequency treatments. However, there is nothing else in common between radio communications/radiation/radioactivity and RF Skin Tightening treatments.

How Radio Frequency Works: The Exact Mechanism

With RF Skin Tightening, an electrical current enters the skin from one pole, which is charged positively, then exits the skin from another, which is charged negatively. A split second later, the polarity changes, and what used to be a positive pole becomes negative and vice versa. This cycle happens hundreds of thousands of times a second.

Now, if the current frequency were much lower, for example, 100Hz (one hundred such polarity alternations per second), we would have a muscular contraction. Such low frequencies are used in TENS machines for pain relief and other physiotherapy machines for muscle rehabilitation.

As mentioned earlier, we do not have muscular contractions at higher frequencies, just heat. The reason is that the frequency is so high that motor nerves are not fast enough to sense the polarity alternation, so no muscular contraction occurs.

Now the question is: how is heat being produced with Radio Frequency? The answer is simple. The heat is generated through random molecular movement. 

With RF currents, the current alternation is so fast that no electrons, atoms, or molecules ever really move towards one pole or the other. As a result, molecules vibrate around a central position or simply rotate. This random molecular movement (vibration or rotation) manifests macroscopically as heat.

In a nutshell, Radio Frequency vibrates our molecules, producing heat.

Which Areas Can We Treat With RF Skin Tightening?

RF Skin Tightening can be used on all major areas of the body for skin that is losing its laxity, including:

  • Whole face, neck, and décolletage area
  • Hips and tummy
  • Arms
  • Legs and thighs
  • Back
  • Buttocks
