Radio frequency

Types of radio frequencies

Radio frequency (RF) is an electromagnetic wave typically used in a variety of aesthetic treatments. The frequencies are converted into heat energy, which then tightens the skin. It is a non-invasive treatment that helps improve the skin's appearance. Different RF technologies are used to achieve this. They include;

• Monopolar RF

  Monopolar RF has only one active electrode that generates an electric field. This field causes the deeper skin layers to heat up, stimulating collagen and elastin production. In most cases, a grounding pad is placed far from the treatment area to create a return path for the currents. The technology is highly effective in treating large body areas. It has a deeper penetration and can cover a larger area. On the downside, it can cause uneven heating and requires more sessions to achieve desired results.

• Bipolar RF

  Bipolar RF uses two electrodes, either in pairs or at a fixed distance apart. It produces a concentrated electric field between the two poles, which penetrates the skin in specific treatment areas. The currents can reach the dermis, subcutaneous fat, or deeper tissues, depending on the design. It is mainly used in home devices and professional machines. Most bipolar RF devices are safe and effective in treating and preventing skin laxity.

• Multipolar RF

  Multipolar RF has more than two electrodes, usually between 4 to 8. It works like bipolar RF but with multiple poles. The electrodes are arranged in pairs along the same axis. Each pair generates an electric field that heats the skin. Multipolar RF is more advanced and utilizes 3D or 4D technology. It can penetrate the skin more evenly and reach deeper layers without heating the surface. As a result, it reduces the risk of burns and discomfort during treatment. Moreover, it requires fewer treatment sessions to achieve the desired results.

• Unipolar RF

  Unipolar RF uses a single electrode that creates a unipolar electric field. The currents can go deep into the body and subcutaneous fat layers. It is often used in body contouring and skin tightening. A grounding pad is placed on the patient's body to return the currents.

How to choose radio frequencies

• Consider the Treatment Area

  The area of concern on the face or body will determine the device used. Devices that target small areas, such as the crow's feet around the eyes, can be handheld. Larger areas, like the entire face or stomach, may need a more extensive system with interchangeable parts.

• Desired Results

  The results that people want to achieve can also influence the equipment chosen. If deep wrinkles, sagging skin, or cellulite needs to be treated, a system that provides high RF energy may be needed. Systems with lower RF energy may be adequate for treating fine lines, tightening the skin, and removing localized fat.

• Device Versatility

  Some RF devices are limited to one treatment, while others can perform various treatments. This includes skin tightening, wrinkle reduction, facial and body contouring, and treating cellulite. Buying a versatile device or system will allow for many different types of treatments.

• Professional vs. At-Home Devices

  Professional-grade devices are more powerful than at-home models. This allows for more in-depth treatment of skin issues. RF devices used in a clinical setting are safe for use by licensed aestheticians and medical professionals. At-home devices are safe for people to use themselves but may have limited capabilities.

• Read Reviews

  Customer and professional reviews can provide insight into the device's quality. Many brands have ratings and feedback that can be read before making a purchase.

• Consider Treatment Time and Frequency

  How long each treatment takes and how often it needs to be done are essential factors. This is especially true for at-home RF devices. Checking the number of required sessions and how long each one takes is important. Professional devices may offer more advanced technology to provide quicker treatments.

• Device Safety and Side Effects

  Reading reviews and checking the manufacturer's website for information on safety precautions is essential. Many devices have safety features, but it's still important to be aware of any possible side effects. Knowing the risks can help ensure the device is a suitable treatment option for the person.

• Manufacturer and Warranty

  Considering the company that makes the RF device is essential, well-known brands are more likely to have quality products. Also, check if the device has any type of warranty. This shows the manufacturer stands behind their product.

How to use, install, and product safety

How to use

• Cleansing the Face

  Use a mild cleanser to wash the face and remove any dirt or makeup. This prepares the skin for the treatment.

• Applying Conductive Gel

  Apply a generous amount of conductive gel to the treatment area. The gel provides conductivity, allowing the RF waves to penetrate the skin easily.

• Selecting RF Settings

  Choose the desired RF frequency and power level based on the skin treatment area. Most devices have preset options for different concerns, like fine lines, wrinkles, or sagging skin.

• Treatment Technique

  Massage the RF device slowly and steadily in circular or upward motions across the treatment area. Avoid staying too long in one place. Be systematic in covering the entire area.

• Coverage and Consistency
