What is Radio Frequency?

Fri Dec 29 14:18:59 CST 2023

What is radio frequency? Can beauty devices tighten the skin and combat aging? An article exploring the beauty technology of radio frequency beauty devices.

At the age of 25, the collagen in the skin begins to decline rapidly, exacerbated by modern habits such as prolonged computer use, staying up late, and consuming fast food, leading to accelerated skin aging.

So, what exactly is the trendy radio frequency? Is it effective, or is it just a gimmick? Long-term use of radio frequency beauty devices can indeed stimulate collagen regeneration, even improving wrinkles, skin sagging, and other aging issues from the inside out. This article will analyze the benefits of radio-frequency beauty devices and guide you in choosing the right one for yourself.

What types of radio frequency technologies are available on the market? What are the effects of different technologies?

Radiofrequency (RF) is a type of high-frequency alternating electromagnetic wave. The heat generated by high-energy electromagnetic waves heats the skin, stimulating collagen cells after reaching the dermis layer, effectively addressing issues like wrinkles and skin sagging associated with skin aging.

The RF power generally ranges from 3KHz to 300MHz. If the RF frequency is below 300KHz, the low frequency won't effectively heat the dermis layer through energy conversion. While professional monopolar RF treatment systems commonly have an RF power of 6MHz, for safety reasons, household RF devices usually do not exceed 500KHz.

There are several types of RF technologies in the market, including monopolar, bipolar, and multipolar RF.

Monopolar RF: This is the most common RF technology in the medical aesthetics market, penetrating to a depth of over 4mm in the fat layer, offering a fat-dissolving effect. Thermage, a well-known example, uses monopolar RF, and due to its deeper penetration, it may cause stronger sensations of pain.

Bipolar/Multipolar RF: Composed of positive and negative poles, the closer the distance between the poles, the stronger the ability. Bipolar RF offers better controllability of energy, making it safer with relatively fewer side effects, and suitable for frequent use. Most household beauty devices use this technology.

Both technologies operate on the same principle of energy effects, with differences in the way RF energy is delivered and its intensity. Therefore, household beauty devices with lower energy require more frequent use to achieve the effects of professional medical aesthetics.

Who is suitable for using RF beauty devices? What are the benefits of household RF beauty devices? 

Conditions that may benefit from beauty devices:

  • Facial puffiness
  • Well-developed jaw muscles or other facial muscles
  • Facial asymmetry
  • Stubborn double chin
  • Sagging facial and mouth corner muscles
  • Desire to improve fine lines, smile lines, crow's feet, etc.

Benefits of using RF beauty devices:

Less pain: Compared to high RF energy in beauty salons, household RF beauty devices have a milder sensation, making them more suitable for those averse to pain. Long-term use can achieve results comparable to high-frequency salon instruments.

Cost-effective: Although the unit price of household beauty devices is higher, their higher frequency of use makes them more economical in the long run. After proper cleaning, a beauty device can be shared and cost-shared with others (excluding those with skin diseases).

Multifunctional: Many beauty devices on the market serve multiple purposes, such as whitening, spot reduction, moisturizing, and refining skin texture. RF devices provide a pure physical therapy, without thinning the skin or causing dependence, and there's no need to worry about skin rebound.

Convenient with no recovery period: Convenience is a factor modern individuals consider. Household beauty devices are portable and can be used anytime, anywhere without the need for special appointments at a beauty salon. They can be used while watching TV, or providing skin care massage. Moreover, the use of RF beauty devices does not cause any trauma to the skin, eliminating the need for any recovery period. They can be used before special events or holidays, and the tightening and firming effects are immediately visible.
