What is XERF?
XERF is a monopolar RF skin-lifting technology that uses dual-frequency energy to deliver controlled heat through multiple skin levels, stimulating collagen so the skin can look firmer, tighter, and smoother without surgery.
XERF's key difference is the use of 6.78 MHz and 2 MHz energy in one treatment. The 6.78 MHz frequency supports the upper to mid dermis, while 2 MHz can deliver energy deeper toward the subcutaneous fat layer and SMAS area, making it useful for doctor-planned tightening and facial contour support in suitable candidates.
The device also uses Wave Fit Pulse to release energy in pulses and reduce heat spikes, plus Integrated Cryogen Delivery (ICD Cooling) to help protect the outer skin during treatment. Most patients feel deep warmth and cooling rather than severe pain.
How does XERF work?
XERF releases two RF frequencies at the same time to create layered heating in the skin, supporting collagen stimulation, elasticity, and jawline firmness without a surgical incision.
- 6.78 MHz delivers heat to the upper and mid dermis to support collagen and elastin stimulation.
- 2 MHz sends energy deeper toward the subcutaneous fat layer and SMAS area to support tightening and facial contour definition.
- Wave Fit Pulse divides energy into small pulses for smoother and more even heat accumulation.
- ICD Cooling sprays cooling to protect the outer skin while RF energy is delivered.
The doctor selects the treatment tip and depth mode for each area. A shallower mode can support collagen and elastin, a middle mode can support overall firmness, and a deeper mode can address selected fat-layer and laxity concerns. Spider Pattern Effector helps distribute energy evenly across the treatment area.
Which areas can XERF treat?
| Area | Treatment goals | Result details |
|---|---|---|
| Lower face and jawline | Helps tighten lax cheeks, soften heaviness near the nasolabial area, and make the jawline look clearer. | May suit people who want the face to look slimmer and more defined without surgery. |
| Under-chin area | Helps address selected under-chin fullness and skin that lacks firmness. | Uses deeper mode planning and doctor assessment to choose energy settings and treatment area. |
| Neck | Supports neck skin that is mildly lax or has fine lines. | Can be included in a face-and-neck lifting plan when the doctor confirms suitability. |
| Eye area and forehead | Helps fine lines and lax skin around the eye area and forehead look firmer. | A smaller tip and energy level are selected according to the sensitivity of each area. |
| Cheeks and overall skin quality | Supports collagen and elastin stimulation so skin looks firmer, smoother, and tighter. | Results gradually become clearer according to each person's skin response. |

What are the benefits of XERF?
-
-
Softens fine lines
Supports skin structure from within, helping some fine lines look less noticeable.
-
Stimulates collagen and elastin
RF energy supports skin remodeling so the skin can look firmer, smoother, and healthier over time.
-
Supports facial contour and selected fat-layer concerns
Useful for planning around cheeks, jawline, under-chin area, and areas where the skin lacks firmness, after doctor assessment.
-
No surgery and generally no downtime
Most patients can return to daily activities after treatment, with possible temporary redness or mild swelling depending on skin response.
What results can you expect after XERF?
-
Skin and jawline look tighter
Energy reaches target skin layers to help lax skin look firmer and the jawline look clearer in suitable candidates.
-
Fine lines and texture can improve
Collagen and elastin stimulation can help the skin look smoother, firmer, and more refined over time.
-
Results gradually become clearer
Some people feel mild tightness immediately from collagen contraction, but clearer visible change usually develops over 1 to 6 months.
-
Response varies by person
Result duration depends on skin condition, age, lifestyle, and aftercare, so doctor assessment and follow-up are important.
When do XERF results appear?
-
Immediately after
You may feel mild tightness from collagen contraction, with temporary redness or slight swelling. -
About 1 month
Some cases start to notice improved firmness and smoother-looking skin. -
1-3 months
Changes usually become clearer as collagen builds, with firmer, smoother, and tighter-looking skin. -
3-6 months
This is often when results are most visible, with clearer tightening and smoother skin texture. -
Result duration
Results may last about 1 year or up to 18-24 months, depending on skin condition and aftercare.
XERF before and after examples
How to prepare before and after XERF
Before treatment
Prepare information for the doctor
- Tell the doctor about health conditions, implanted electronic devices or metal, and previous procedures in the same area.
- If you recently had filler or botulinum toxin, wait about 2-4 weeks and let the doctor assess before treatment.
- If you recently had thread lifting, you may need to wait about 1 month and be assessed by the doctor first.
- Avoid treatment on skin with open wounds, infection, or active skin disease.
After treatment
Care for skin and follow up
- In general, downtime is not required and you can return to daily life immediately.
- Temporary redness or mild swelling may occur and usually improves within a few hours.
- Use moisturizer and sunscreen regularly after treatment.
- Attend follow-up as scheduled, especially around 1-3 months when results start to become clearer.
What happens during a XERF appointment?
- Consult the doctor for assessment of skin condition, facial structure, and your concerns so the plan can be individualized.
- The treatment area is cleansed before the procedure.
- In general, topical anesthetic is not required, although it may be used in some cases. Preparation may take about 40 minutes to 1 hour.
- XERF treatment begins. The doctor uses the XERF handpiece to deliver energy into the skin. You should feel warmth under the skin rather than severe pain. Energy delivery usually takes about 30 minutes to 1 hour depending on treatment area.
- After treatment, the team cleanses the skin and you can continue daily activities without downtime.
- Aftercare includes regular moisturizer and sunscreen.
- The clinic schedules follow-up around 1-3 months, when results begin to become clearer, so the doctor can assess lifting response and skin reaction. If questions or unusual symptoms occur, you can contact the clinic for ongoing support.
How XERF compares with other lifting options
| Treatment compared | How XERF differs | What it means when choosing |
|---|---|---|
| Ulthera (MFU-V) | XERF is monopolar RF using two frequencies, 6.78 MHz and 2 MHz. Ulthera uses focused ultrasound at 3.0 and 4.5 mm with DeepSEE imaging. | Ulthera has been used for lifting for a long time, while XERF is an RF-based option rather than ultrasound. Choice should depend on target layer and doctor assessment. |
| SofWave | XERF is RF, while SofWave is ultrasound that works at a relatively shallow skin level around 1-2 mm. | SofWave is suited to shallower dermal support, while XERF is an RF option with 3 depth modes. The doctor should choose based on skin concern. |
| Thermage FLX | XERF and Thermage FLX are both monopolar RF, but XERF uses two frequencies, 6.78 MHz and 2 MHz, while Thermage FLX uses one 6.78 MHz frequency. | Thermage FLX has long been used for wrinkles and laxity. XERF is a newer RF option with multiple depth modes, so case-by-case assessment matters. |
| General HIFU | XERF is RF, not ultrasound. HIFU covers many ultrasound devices with different depths, frequencies, and standards. | HIFU results vary by device and protocol. XERF is an RF option with adjustable modes, so the equipment and doctor assessment should guide the choice. |
How much does XERF cost?
XERF starts from 27,000 THB at Privato Clinic.
Factors that affect XERF pricing
- Treatment area, such as face, jawline, under-chin area, eye area, or neck
- Shot count and treatment-area size, such as full face or full face with neck
- Laxity level, skin quality, and depth mode selected by the doctor
- Standalone treatment or planning together with another lifting program
- Current clinic promotion or package at the time of inquiry
Because XERF plans differ by skin condition, laxity level, and individual goals, Privato Clinic confirms the price and treatment plan after assessment rather than quoting a one-size-fits-all final price.
