Unveil HIFU Treatment: How Many Sessions Will You Need to See Ideal Result

1. What is HIFU

HIFU technology utilizes precise focused ultrasound energy to penetrate the epidermis and reach deep skin tissues. When ultrasound is focused on the target tissue, a high temperature of 60-75℃ is instantly generated, which is sufficient to cause the collagen molecular structure of the dermis and fascia layers to contract instantly, while activating fibroblasts and initiating the regeneration and recombination process of collagen. This thermal effect can penetrate up to 4.5mm deep into the SMAS fascia layer, which is the key to facial support structures.

Unlike lasers or radiofrequency that only act on shallow layers, the energy of HIFU can penetrate to depths that traditional techniques cannot reach, forming thousands of tiny thermal damage points under the skin through focal thermal coagulation effect. Without damaging the epidermis, it stimulates the skin’s natural wound healing response and promotes continuous collagen regeneration.

2. Time Trajectory of Effect Manifestation After the First Treatment

2.1 Immediate Effects (1-7 days after treatment)

After the first treatment, about 30% of the tightening effect can be immediately manifested. This is mainly due to the immediate contraction response of collagen fibers after heating, at which the facial contour lines begin to become clear, especially in the mandibular margin area. But this stage is often accompanied by mild edema, redness or tenderness, which is a normal reaction and usually subsides on its own within 48-72 hours. Some patients may feel local muscle soreness and weakness, and these reactions usually disappear completely within 3-4 days.

2.2 Collagen Neogene Stage (1-3 months)

The key physiological changes after treatment quietly occur at this stage. Activated fibroblasts begin to synthesize new collagen, but this biological process requires continuous accumulation. About 4 weeks after surgery, the patient gradually felt an improvement in skin texture – an increase in pore fineness and a smoother texture. After 8 weeks of treatment, superficial fine lines (such as dry lines around the eyes and horizontal lines on the forehead) showed a trend of fading. Research has shown that the synthesis of collagen at this stage has reached 1.5 times the baseline value, laying the foundation for significant effects in the future.

2.3 Peak Effect Period (3-6 months)

At this moment, we are entering the golden age of HIFU effects. The continuous lifting of the fascia layer causes the apple muscle to move up, reducing the depth of the nasolabial folds by 30% -50%, and significantly tightening the lower contour line. A three time course participant described, “After the third treatment, the originally sagging muscle tissue returned to its original position, and the side profile lines were more than five years younger than six months ago.” Clinical data shows that at this stage, the amount of collagen production reaches its peak, and the facial lifting effect is fully manifested.

3. Key Factors Determining the Frequency of Treatment

3.1 Grading of Skin Aging

For the age group of 25-35, the skin elasticity still exists and the collagen metabolism ability is strong. A single treatment combined with strict sun protection and moisturizing can achieve an improvement rate of over 60%. However, those over 45 years old who seek beauty, especially those with obvious mandibular laxity and lower zygomatic fat pad, often require 2-3 sessions of combined treatment. The layered treatment strategy is particularly important here – the 3.0mm depth probe improves deep dermal laxity, while the 4.5mm depth probe specifically lifts the SMAS fascia layer. The dual layer effect is necessary to effectively combat gravitational aging.

3.2 Differences in Individual Collagen Regeneration

The activity of fibroblasts directly determines the therapeutic effect. Smokers, those who stay up late for a long time, or those with vitamin deficiencies generally have a 30% -40% decrease in cell regeneration ability and need to increase the frequency of treatment. Clinical findings have shown that patients who receive antioxidant supplements (such as vitamin C and vitamin E) one month before surgery have an average increase of 20% in collagen regeneration rate and a significant improvement in single dose efficacy. This is also why professional organizations emphasize the importance of internal and external joint repair.

4. Scientific Basis for Treatment Interval

Collagen metabolism follows a strict physiological cycle. The complete regeneration cycle from fibroblast activation to collagen maturation and deposition takes 90-120 days. Early secondary treatment (with an interval of less than 3 months) not only damages the fragile collagen network in newborns, but may also lead to abnormal scar tissue proliferation. Multiple clinical institutions suggest:

• Basic consolidation course: 3-4 months between the first and second treatments, strengthening the collagen scaffold structure
• Effect maintenance stage: Extend the interval between subsequent treatments to 6-12 months to promote continuous optimization of collagen
• Long term maintenance plan: maintenance therapy once a year to offset collagen loss caused by natural aging

5. The Correlation Between the Treatment Courses and the Persistence of the Effect

5.1 Duration of Single Treatment Effect

After the first HIFU, collagen proliferation can last for 6-9 months, but the effect maintenance shows a parabolic change. At 12 months after surgery, about 60% of the peak effect is retained. After 18 months, due to natural metabolic loss, the effect decreases to about 40%. Proper maintenance (strict sun protection+skin moisturization) can extend the one-year maintenance period to 1.5 years.

5.2 Cumulative Effects of Multiple Treatments

After three standardized treatment courses (with an interval of 3-6 months), the fascia layer forms a dense collagen network structure, and the lifting effect undergoes a qualitative change. The data shows that those who complete the full course of treatment can achieve a duration of 2-3 times longer than a single treatment. More importantly, multiple stimuli induce fibroblasts to enter an “activated memory state”, which subsequently enhances collagen synthesis ability and results in a more long-lasting anti-aging effect.

6. The Doubling Mechanism of Postoperative Care on Therapeutic Efficacy

The skin after HIFU treatment is like “plowed soil” and urgently needs nutritional reconstruction.

6.1 72-hour Golden Repair Period

The high-energy thermal effect leads to a 30% increase in transcutaneous water loss, requiring immediate use of moisturizing products containing ceramide and hyaluronic acid. Avoid using irritating ingredients containing alcohol, fruit acids, and retinoids to prevent damage to the newly formed stratum corneum.

6.2 Biological Significance of Sun Protection

Ultraviolet radiation is the number one killer of collagen, capable of decomposing over 50% of newly formed collagen fibers. Three months after treatment, daily use of SPF50+broad-spectrum sunscreen is required, especially for UVA (marked as PA+++or above), to prevent collagen degradation caused by matrix metalloproteinase activation.

7. Innovative Highlights of Nubway HIFU Devices

Nubway’s HIFU device leads the market with three core technological advantages: Firstly, its unique real-time ultrasound imaging system can accurately locate the treatment level, ensuring safety while achieving optimal therapeutic effects. Secondly, the innovative adjustable treatment plan can intelligently match different skin types and sensitivities, providing personalized solutions for various skin problems. Finally, this non-invasive technique provides a safe and convenient surgical alternative for those seeking beauty by accurately focusing on a single treatment to stimulate long-term collagen regeneration without the need for a recovery period and with long-lasting effects.
