Tiếng ViệtSagging, less firm skin and wrinkles are signs of aging that worry many people. Among the non-invasive skin rejuvenation methods available today, HIFU and RF are frequently mentioned due to their ability to lift the skin, improve elasticity, and stimulate collagen production effectively. So what are HIFU and RF, how do these two technologies work, and how do they differ? This article from HBIO Clinic will help you understand and choose the most suitable skin rejuvenation method for your skin condition.
What are HIFU and RF?
HIFU and RF are both non-invasive skin rejuvenation technologies widely used in modern aesthetics, helping to improve the appearance of aging skin without surgery or downtime.
HIFU (High Intensity Focused Ultrasound) is a technology that uses high-intensity focused ultrasound waves to penetrate deep into the SMAS layer – the skin’s structural support layer. Thanks to its ability to create precise heat points at a depth of 3.0 – 4.5mm, HIFU strongly stimulates collagen and elastin production, helping to lift and firm the skin and significantly improve sagging.
RF (Radio Frequency) is a skin rejuvenation technology that uses high-frequency waves to heat the dermis and hypodermis layers. The thermal energy from RF stimulates collagen regeneration, improves elasticity, makes skin firmer, smoother, and reduces fine wrinkles. RF provides a gentle treatment experience, suitable for prematurely aging skin or skin requiring regular rejuvenation.
What is the difference between HIFU and RF?
HIFU and RF are both non-invasive skin rejuvenation technologies widely used in modern aesthetics. The comparison table below will help you understand the differences between HIFU and RF so you can choose the right method for your needs.
| Comparison criteria | HIFU technology | RF technology |
| Depth of impact | High-intensity focused ultrasound waves penetrate deep into the SMAS layer (3.0 – 4.5 mm). | RF (radiofrequency) waves primarily affect the dermis and superficial subcutaneous tissue (1.5 – 3.0 mm). |
| Skin lifting and rejuvenation effects | Noticeable lifting effect, improved sagging, and contoured facial features. | Firms the skin, improves mild signs of aging, and reduces skin elasticity. |
| The feeling during treatment | A tingling sensation, a slight warmth in the affected area. | Gentle, pleasantly warm, and almost painless. |
| Duration of effectiveness | Collagen continues to regenerate after treatment for 12-18 months. | 6-12 months, requires regular maintenance treatment. |
| Implementation costs | Higher price due to deeper impact and noticeable lifting effect. | Lower cost, suitable for routine skincare. |
Comparing the price list and costs of HIFU and RF treatments
The cost of HIFU and RF treatments differs significantly due to their intensity and the technology used. HIFU is generally more expensive because it penetrates deep into the SMAS layer of the skin, providing a noticeable and longer-lasting lifting effect. RF, on the other hand, primarily targets the dermis to improve firmness and stimulate collagen production, resulting in lower costs but requiring more treatment sessions.
| Technology | Reference cost | Number of sessions usually performed | Characteristic |
| HIFU | Approximately 10-25 million VND per session (full face), smaller areas around 5-10 million VND. | 1-2 times/year | Deep impact, noticeable lifting effect, long-lasting results. |
| RF | Approximately 1-5 million VND per session, depending on the treatment area. | 4-6 sessions/treatment | Firms the skin and improves fine wrinkles. |
In reality, the cost can vary depending on the technology used, the area being treated, the skin condition, and the reputation of the aesthetic clinic. Therefore, customers should have a direct consultation to determine the appropriate method and optimal treatment plan for their skin.
Suitable candidates for HIFU and RF treatments
Both HIFU and RF are non-invasive skin lifting and rejuvenation technologies; however, each method is suitable for different skin conditions. Choosing the right technology helps to achieve optimal results and maintain long-lasting effects.
HIFU is suitable for people with visible signs of aging such as sagging skin, deep wrinkles, loss of facial firmness, or the beginning of sagging in the cheeks, chin, and neck. This technology penetrates deep into the SMAS layer under the skin, effectively lifting and improving skin elasticity. Therefore, it is often chosen for people aged 30 and older or those who want a noticeable lifting effect without surgery.
Meanwhile, RF (Radio Frequency) is suitable for people with mild aging, skin that is beginning to lose firmness, small wrinkles, or those who want to maintain healthy, firm skin. RF mainly acts on the dermis to stimulate collagen and elastin production, helping to firm the skin, improve elasticity, and smooth the skin surface. This method is usually suitable for people aged 25 and older or those who want to care for and prevent early aging.
