XERF vs Thermage: A New Era of Laser Skin Tightening in Korea

If you’re looking for a skin lifting laser with no downtime, no anesthesia, and visible results, XERF RF Lifting may be exactly what you need. Often called a “stick-and-tighten” treatment by patients, this minimally invasive lifting procedure is taking Korean dermatology by storm. RF treatments target the deep layers of the skin to stimulate collagen production and improve skin texture. Laser treatment is also effective on areas like the upper arms, providing targeted energy delivery to improve skin elasticity and reduce wrinkles. Here’s everything you need to know about how it compares to Thermage, which utilizes heat energy to safely warm the collagen-rich layers of the skin.

Introduction to Non-Surgical Skin Tightening

Non-surgical skin tightening is a popular cosmetic procedure designed to firm sagging skin and improve skin tone without the need for invasive surgery. This skin tightening procedure uses targeted energy to heat deeper layers of the skin, stimulating collagen and elastin production. As a result, the skin becomes firmer and more youthful-looking. Non-surgical skin tightening treatments are ideal for individuals looking to address signs of aging, such as loose skin, without undergoing cosmetic surgery. With various skin tightening procedures available, including ultrasound skin tightening and intense pulsed light, individuals can choose the best treatment to suit their skin type and concerns. These treatments offer a convenient and effective way to rejuvenate the skin and achieve a more youthful appearance.

What Is XERF? A Next-Generation RF Lifting Device

All lifting devices work by generating heat deep within the skin to stimulate collagen and tighten tissue. Micro focused ultrasound is a non-surgical technology used in skin tightening treatments that stimulates the production of collagen and elastin. These devices vary by energy type and send heat deep into the skin to achieve a tighter and lifted appearance while reducing wrinkles:

• Ultrasound: Ultherapy, Sofwave
• Microwave: ONDA
• Light-based: BBL, Titanium
• RF (Radiofrequency): Thermage, Oligio, and now XERF

XERF, developed by Korea’s top laser company Lutronic (in partnership with Cynosure), is a monopolar RF device—the same category as Thermage—but with key technological upgrades.

Thermage vs XERF – 3 Major Differences

1. Dual-Frequency = Deeper Collagen Stimulation

Thermage uses a standard 6.78 MHz frequency.
XERF, however, combines 6.78 MHz and 2 MHz, penetrating multiple skin depths and enhancing overall collagen remodeling.

2. Advanced Cooling = High Energy, Low Risk

To remodel collagen, the skin must reach 55–65°C—but overheating risks burns.
XERF delivers up to 12 cooling bursts per shot, allowing higher energy with minimal discomfort or injury.

3. Greater Surface Area = More Efficient Treatment

• Thermage tip: 4cm²
• XERF tip: 6cm²

XERF covers more skin with each shot—delivering results with fewer shots and less time.

Addressing Signs of Aging with XERF

XERF is a non-surgical skin tightening treatment that targets the deeper layers of the skin to trigger collagen production. This advanced treatment is highly effective in addressing signs of aging, such as sagging skin, fine lines, and wrinkles. By using radiofrequency energy to heat the skin, XERF stimulates the production of new collagen and elastin, resulting in firmer, smoother skin with improved skin tone. XERF is suitable for various skin types, including darker skin tones, and can be used to treat a range of areas, including the face, neck, and body. This makes XERF a versatile and powerful option for those looking to rejuvenate their skin and combat the effects of aging.

Why XERF Is Booming in Korea

1. Delivers More Energy per Shot

• Thermage 300 shots = ~30,000J
• XERF 300 shots = 44,000–52,000J

This means 300 XERF shots can equal or exceed the energy of 450–600 Thermage shots.

2. Significantly Less Pain

XERF uses Wave Fit Pulse technology to adjust output based on skin resistance—dramatically reducing pain.
At Noonopi, topical anesthesia is rarely needed.

3. Better Cost Flexibility

• Thermage 300shots: ~$2,000+
• XERF 300shots : ~$1,000 with higher energy delivery

Thermage tips expire in 3–4 hours, requiring full use in one session. XERF has no such limitation—ideal for customized care or combined procedures.

Customized Treatment Plans with XERF

Customized treatment plans are essential for achieving optimal results with XERF. A qualified cosmetic surgeon or skincare professional will assess the individual’s skin condition, medical history, and desired results to create a personalized treatment plan. This may involve a single treatment session or a series of treatments, spaced several weeks apart. XERF can be combined with other skin rejuvenation treatments, such as laser treatments or skincare products, to enhance results. By tailoring the treatment plan to the individual’s needs, XERF can provide noticeable results, improving skin laxity and restoring a more youthful appearance. This personalized approach ensures that each patient receives the most effective and appropriate care for their unique skin concerns.

Is XERF Safe After a Facelift?

Most doctors suggest waiting 2–6 months post-surgery before any lifting laser. However, this is based on anecdotal guidance. While non-surgical treatments like laser skin tightening have fewer risks compared to surgical face lifts and other cosmetic surgeries, they are also less effective and should be performed by qualified professionals. Noonopi Plastic Surgery and Lutronic conducted a joint clinical study applying XERF during the early healing phase after facelift surgery.

The results confirmed that XERF is safe for early-stage post-op use, without disrupting healing or increasing complications. Some patients may experience temporary redness or minor swelling after treatment, which typically resolves within 24 hours.

Maintaining Results After XERF Treatment

To maintain the results of XERF treatment, it is essential to follow a consistent skincare regimen and practice sun protection. This includes using broad-spectrum sunscreen, avoiding harsh skincare products, and maintaining a healthy lifestyle. Individuals may require multiple treatments to achieve desired results, and maintenance treatments may be necessary to sustain the effects of XERF. With proper care and maintenance, the results of XERF can last for several weeks to up to three years, depending on the individual’s skin condition and treatment plan. By combining XERF with other non-surgical treatments, individuals can enjoy long-lasting, radiant skin with improved skin tone and texture. This comprehensive approach ensures that the benefits of XERF are maximized and maintained over time.

Who Should Consider XERF RF Lifting?

You may benefit from XERF if you:

• Have mild to moderate sagging in the lower face or cheeks. XERF can also help reduce the appearance of wrinkles and crepey skin by stimulating collagen and elastin production.
• Want skin tightening without surgery or downtime. Patients might experience mild discomfort, such as tingling vibrations, during the treatment.
• Found Thermage too painful or expensive
• Seek early rejuvenation after facelift
