In the pursuit of skin tightening and youthfulness, ultrasonic guns and radiofrequency devices have become popular beauty instruments that many beauty lovers are concerned about. They both seem to be related to anti-aging, but they play many different roles on the skin. An in-depth understanding of these differences will help us to more accurately choose the right instrument for our skin needs.
Principle of the big secret
Ultrasonic gun
The ultrasonic gun uses high-energy focused ultrasound technology to precisely focus energy on different layers of the skin, such as the SMAS fascia layer, the deep dermis and the superficial layer. When the ultrasound energy is instantly released at the target level, the resulting thermal effect can rapidly increase the local temperature to 60 - 70 ℃. This high temperature causes the water molecules in the skin tissue to vibrate at high speed, which causes collagen fibres to contract and denature, and stimulates fibroblasts to synthesise more new collagen.
Radiofrequency (RF)
Radiofrequency devices utilise the thermal effect produced by radiofrequency currents. Radiofrequency energy is introduced into the skin through electrodes, so that the polar molecules (mainly water molecules) in the skin vibrate rapidly and generate heat by friction in the direction of the radiofrequency current. When the dermis is heated, the temperature can rise to 40 - 45°C. This temperature range activates collagen fibres, causing them to contract instantly and stimulating collagen renewal and restructuring over time.
Difference in Levels of Action
The energy of the ultrasound gun reaches the deeper layers of the skin, especially the SMAS fascia. This layer is located deep in the skin and plays a key role in maintaining the overall firmness of the face. By acting on the SMAS fascia layer, the ultrasonic gun can effectively lift sagging facial tissues, improve the appearance of lines, jawline blurring and other problems, to achieve deep-level firming and lifting effect. While the action level of the radiofrequency instrument mainly focuses on the dermis layer. Although it can also play a tightening effect on the skin, it is relatively weaker than the ultrasonic gun in terms of lifting effect because it cannot penetrate into the SMAS fascia layer like the ultrasonic gun. However, the effect of radiofrequency instrument on the dermis can effectively improve the skin texture, so that the skin becomes more delicate and smooth.
Different focus of efficacy
The ultrasonic cannon is particularly good at lifting and firming. It can significantly improve facial contours, making loose facial lines firm and uplifted again, giving the face a more three-dimensional and youthful look. For sagging facial tissues due to ageing, such as sagging apple muscles and drooping corners of the mouth, the ultrasound gun is more effective in improving the results. The radiofrequency device, on the other hand, focuses more on skin tightening and skin texture improvement. It stimulates the continuous regeneration of collagen, which effectively reduces fine lines and enhances the elasticity and radiance of the skin. Long-term use of a radiofrequency device can give the skin a firm, plumped-up appearance, which is more suitable for the prevention of skin ageing as well as the improvement of minor skin laxity problems.
Applicable skin type has its own focus
Due to its higher energy levels, the ultrasound gun is more suited to mature skin with more severe skin laxity and sagging facial tissues. This type of skin needs a stronger stimulus to activate the repair and regeneration of the deeper tissues, and the Ultrasound Cannon is able to fulfil this need. However, for people with thinner, more sensitive skin, the use of ultrasound cannons may cause some burden on the skin and needs to be chosen carefully. The relatively gentle energy of radiofrequency devices is applicable to a wider range of skin types. Whether it is oily, dry or combination skin, as long as there are signs of the first signs of aging such as skin laxity and fine lines, they can be improved by the radiofrequency device. Especially for people with more sensitive skin, the relatively gentle stimulation of the RF instrument ensures certain results while requiring relatively low tolerance of the skin.
When choosing between an ultrasonic gun or a radiofrequency device, one needs to consider factors such as the condition of one's skin, the degree of aging, and one's personal expectations of treatment results. Only in this way can the advantages of these cosmetic instruments be fully utilised to bring the best skin care results.
