If you are a regular customer of a beauty salon or you just own a beauty salon, you must have heard about or even used the HIFU beauty machine. Maybe you have used it many times yet still are confused about the essence and principle of the HIFU machine. Today this article will give you a clear review of what is HIFU machine and how does HIFU machine work on earth.

What is HIFU Machine

High intensity focused ultrasound is a non-invasive and safe technology. It uses focused ultrasound waves to treat various medical conditions, including cancer, uterine fibroids, and skin aging. It is now commonly used in beauty devices for lifting and tightening the skin.

A HIFU machine uses high-frequency ultrasound to heat the skin in the deep layer, thus promoting the regeneration and reconstruction of collagen. You can use the HIFU machine in particular targeting areas like the forehead, the skin around the eyes, cheeks, chin, and neck, etc.

How Does HIFU Machine Work

  • Heating and Regeneration

The high intensity focused ultrasound wave can penetrate subcutaneous tissue in a targeted and direct way, so the treatment area would generate heat in a short time. The subcutaneous tissue will generate heating under high-frequency vibration. And when the temperature is up to certain degree, the skin cells would regrown and increase.

More importantly, the ultrasound wave can be effective without damaging the skin or issues around the targeted areas. within 0 to 0.5s, the ultrasound wave can quickly access the SMAS (Superficial Musculo-Aponeurotic System). And within 0.5s to 1s, the temperature of MAS can arise to 65℃. Therefore, the heating of SMAS triggers collagen production and tissue regeneration.

  • What Is SMAS

The superficial Musculo-Aponeurotic System, also known as SMAS, is a layer of tissue in the face that is composed of muscle and fibrous tissue. It separates the facial skin into two parts, the deep and superficial adipose tissue. It connects the fat and facial superficial muscle, which is important for supporting the whole facial skin. The high-intensity ultrasound waves penetrate into the SMAS promoting the production of collagen. Hence lifting the skin.

What Does HIFU Do to Your Face

When we use the HIFU machine on our face, the high-intensity ultrasound wave will act on our deeper facial skin, heating up the cells and stimulating collagen. Once the cells of the treatment skin heat up to a certain temperature, the collagen will generate and increase.

Therefore, the face will go through some positive changes after the treatment. For example, our skin will be tightened and firmer, and the wrinkles would be improved obviously. Anyway, the HIFU machine will possibly bring you a more youthful and glowing appearance after you receive a regular and a certain period of treatment. 

How Long Does HIFU Take to Show Results

Under normal conditions, if you receive HIFU facial care in a beauty salon, you will see improvement in your face and skin. When you finish the treatment and look at your face in the mirror, you will be happy to find that your face has really been lifted and tightened.

However, for a beginner receiving HIFU treatment, it is recommended to do the HIFU 2 to 3 times a week for the first 5 to 6 weeks. And then gratifying results and full effects might happen within 2 to 3 months.

What Are the Disadvantages of HIFU

Although HIFU is very common and effective in face lifting and tightening, and wrinkle removal, it still has some side effects.

  1. Not 100% painless

Many people will feel a little uncomfortable and pain at the beginning when using the HIFU machine. But most people can accept it after a period of adaptation.

  • Not a one-time treatment

The results of HIFU treatment also depend on the ability of the self-rejuvenation of skin and cells. So the final results might be different from person to person. However, for most people, the results will be positive as long as you receive a period of treatment. Even though it might require repeated treatments to maintain the best results.

  • Swelling and redness may appear

After using the HIFU machine, there might appear a little swelling and redness. But it is ok because it normally disappears within a few days.

Most of the side effects can be avoided only if your treatment is under a professional operation with a professional HIFU machine. Some advanced devices with faster shot speeds and shorter intervals would bring less pain than other normal machines.
