The difference between HIFU and RF
The introduction of HIFU (High Intensity Focused Ultrasound) seems to be announced to the world: “I have achieved a comprehensive victory in the field of tightening!” Is this really true? Many patients will ask: “If you have done HIFU, isn’t the RF Radiofrequency package bought in the beauty salon was wasted?” It seems that many people are not aware of the difference between promotion and compaction. It will confuse the different effects of HIFU and RF, so that there may be a “buy the wrong course of treatment”.
The difference between Lifting and Tightening is that “tightening” refers to the tightening of the skin; while “uplifting” means pulling up. The energy must go deep into the tendon film SMAS (Superficial Musculo). -Aponeurotic System) can be done. The general radio frequency heat can only be delivered to a subcutaneous depth of 2 to 3 mm, which stimulates the proliferation of collagen, so it can only make the skin firmer.
The SMAS tendon film, like a fishing net, is responsible for grasping the connective tissue of the skin and muscles and showing the contours.
“Papi” is a kind of radio frequency, and the effect is to tighten the skin.
The radio wave that was once popular has claimed that the effect can last for one year. Although there is the term “pupi”, it is actually only one type of radio frequency. The effect is to tighten the skin.
At present, HIFU machines have been approved by the US FDA to confirm their effectiveness in tightening, ensuring that sufficient and stable heat can be delivered to the 4.5 mm SMAS for facial and neck lift. Therefore, before purchasing any treatment, remember to have a deep understanding of the main functions, side effects, etc. of these technologies, so as not to buy the wrong treatment, spend money, spend time, and finally make it happen!
Regarding HIFU technology, I believe that everyone will not feel forced, but RF may be less familiar. The radio frequency is divided into unipolar and bipolar. The annual radio wave skin is a unipolar radio frequency technology. This type of treatment is best operated by a doctor because of the higher energy and greater risk. During the course of treatment, a piece of metal is placed on the back of the patient. When the current enters the skin through the handpiece, the current is led out from the metal piece to form a complete circuit. Since the heat is heated from the entire surface of the skin, the patient has to suffer a certain degree of pain, but if the heat energy generated is insufficient, the skin will be reduced. There are also many users sharing the benefits on the Internet, but the overall evaluation is not very good (www.realself.com), and there are medical clinical research reports that about 25% of the testers did not achieve the expected results.
General RF heat can be delivered to a subcutaneous depth of 2 to 3 mm, stimulating collagen hyperplasia and tightening the skin.
Technology continues to advance, and in recent years there have been many different forms of RF, including segmented RF and micro-pin RF. In the past, RF technology used to heat a large area of tissue, which made it easy to overheat or burn the skin layer. However, the segmented radio frequency was dispersed point by point, point by point, to reduce the discomfort of the epidermis, but also had the opportunity to reduce the skin. Energy, so the course of treatment is relatively frequent compared to radio waves, such as once a month.
Another newer RF technology is micro-needle type, which first inserts several rows of micro-needles into the skin, and then releases the radio frequency, so that the heat can directly reach the bottom layer of the skin, producing a targeted effect, triggering collagen proliferation and firming the skin. And reduce damage to the epidermis. It is said that this treatment also helps the pores and bumps, but it is necessary to pay attention to the microneedle wound care after the treatment to avoid infection and inflammation.
Now that you know the difference between RF and HIFU in terms of principle and function, you will understand that the two can’t completely replace each other! Instead, they should complement each other. The above-mentioned FDA-approved HIFU machine is only treated for about one year. During this period, if you want to look more firm on the skin, or if you want to have a better state in an important occasion, you can use RF treatment as a maintenance, consolidation or Strengthen the firming effect. However, it should be noted that all medical cosmetic treatments should be adequate, not excessive, too dense, otherwise it will not be worth the candle!
