What is the working principle of the HIFU machine?
During a HIFU session, the practitioner places a handpiece on the skin and delivers ultrasound energy at controlled depths. The energy passes through the skin’s surface without damage.
It targets deeper layers that need tightening. As the tiny thermal points form, the body begins a natural healing response. Over the following weeks, the treatment stimulates new collagen and reorganizes existing collagen fibers, which gradually improves firmness and elasticity.
Results are usually progressive rather than instant. Many people notice early tightening.
The main lifting and contouring effect usually becomes clearer over 2 to 3 months. This happens as collagen production increases. Results can last for months, depending on the treated area and your skin condition. Some patients choose maintenance treatments to keep the effect.
Clinicians commonly use HIFU for the jawline, cheeks, neck, and under-chin area. You can also use it on certain body areas to achieve mild tightening and contouring.
Treatment time varies by area. You may have temporary redness, swelling, tingling, or tenderness afterward. These effects usually go away within a short time.
What is the function of each treatment cartridge on the HIFU machine?
The HIFU machine utilizes cartridges designed for different depths, targeting specific skin layers:
| Probe Depth | Target Layer | Primary Use |
| 1.5 mm | Superficial Dermis | Fine lines, eye area, pores |
| 3.0mm | Deep Dermis | Skin tightening, collagen regeneration |
| 4.5mm | SMAS Layer | Lifting, V-face shaping, contour enhancement |
| 6mm | Superficial Fat | Double chin, small-area contouring |
| 8mm | Body Fat | Waist/abdomen, arms |
| 10mm | Deep Fat | Body contouring |
| 13mm | Deeper Fat | Abdomen, thighs, large-area fat reduction |
Why are multiple cartridges typically used in combination?
Treatments rarely rely on a single cartridge; instead, a combination of cartridges is used to target different layers:
For example, in facial anti-aging treatments:
4.5mm: Lifts the SMAS layer and improves facial contours.
3.0mm: Stimulates collagen production in the dermis and enhances skin firmness.
1.5mm: Improves fine lines around the eyes and mouth, as well as overall skin texture.
For body contouring, the combination might include:
13mm: Targets deep fat layers to reduce fat volume.
8mm: Treats mid-layer fat to refine contours.
6mm: Tightens superficial tissues to help improve skin laxity.
Before & After
Generally, an immediate lifting effect can be seen after just one HIFU treatment, with visible improvements to the skin. For optimal results, a course of 1 to 3 sessions spaced 3-6 month apart is recommended. To maintain these perfect lifting effects, an annual maintenance treatment is advised.
HIFU vs RF
Radio Frequency (RF) and High-Intensity Focused Ultrasound (HIFU) are common treatments found in beauty salons. While many people often confuse these two procedures, they are actually quite distinct in how they work and the results they provide.
| Technology | Depth | Best For |
| HIFU | SMAS | Lifting |
| RF | Dermis | Skin Tightening |

FAQ
Does HIFU hurt?
No, it doesn’t hurt; it’s just slightly uncomfortable, but clients find it very manageable.
Is HIFU permanent?
The results of HIFU machine is not permanent. it need Consolidation therapy is administered once a year.
How many sessions?
Most people need 1 to 3 sessions for a standard High-Intensity Focused Ultrasound (HIFU) facial. Sessions are typically spaced 3 to 6 months apart to let your skin’s collagen fully rebuild.
What age is best for HIFU?
HIFU treatment is ideal for individuals aged 30 and above, as this is when natural collagen loss typically begins. By stimulating the production of new collagen, HIFU effectively restores skin elasticity
Is HIFU safe?
Yes, it is totally safe. As long as the operator follows standard procedures.
