As the world’s first dual monopolar RF treatment for non-invasive skin tightening and rejuvenation, there is no doubt that XERF continues to make a buzz in the medical aesthetics industry, both local and international. SpectruMed is the exclusive distributor of XERF, one of the most extraordinary premium devices from Cynosure Lutronic, in the Philippines.
With years of experience in dermatology, anti-aging medicine, and lifestyle medicine, Dr. Smith Arayaskul from Thailand, constantly works on patients across a rich range of skin types and aging concerns. This is why XERF is beneficial in his practice, describing it as colorblind because it can give exceptional results with low risk of side effects on patients with different skin types.
In this exclusive interview, Dr. Smith Arayaskul breaks down what makes XERF different compared to traditional lasers when it comes to skin tightening and why he believes selectivity, not raw energy, is what delivers lasting results for both patients and clinics.
TREATMENT TECHNOLOGY
How Does XERF’s Monopolar RF Reach Deeper Than Other RF Devices?
In an era where monopolar RF machines are everywhere, Dr. Smith Arayaskul says XERF stands apart because of something rooted in physics: frequency selectivity. “I think this has come from a very understanding in basic science that can make the frequency different from others,” he explains.
XERF uses dual frequencies, 6.78MHz and 2MHz, operating in three distinct depth modes, each targeting a specific tissue layer. Rather than delivering energy broadly across the face, each mode is designed to achieve a clear anatomical goal.
- Shallow: Targets the outermost skin layers with high precision and very controlled energy delivery
- Middle: Reaches the dermis — the key zone for collagen production and structural skin tightening
- Deep: XERF uses dual-frequency technology to penetrate even further, supporting subcutaneous rejuvenation
“We have the mode that’s going very shallow and very precise, we have the middle mode that’s going to the dermis, and last but not least, this was the deep mode that’s mixing with dual frequency that’s aiming deeper, even at your subcutaneous rejuvenation,” Dr. Smith Arayaskul explains.
Thailand’s Dr. Smith Arayaskul says XERF is an excellent technology, as it has a real-time surface temperature monitoring system that prevents the risk of burns and patient discomfort.
PATIENT SAFETY
How Do You Keep Patients Safe When Using Higher Energy Levels with XERF?
For Dr. Smith Arayaskul, safety is not an afterthought; it shapes every treatment decision. And with XERF, he says the technology is excellent, as it has a real-time surface temperature monitoring system, which ensures optimal heat delivery while preventing excessive temperature build-up and reducing the risk of burns or patient discomfort.
“The system that can give us the direct and real-time feedback, this is super important,” Dr. Smith Arayaskul says. “With XERF, we can really see the surface energy that is on your skin, so we can control the technique and also the energy to launch the right amount of it.”
Beyond the numbers on screen, safety also comes from how XERF delivers its energy. The waveform is designed to build heat gradually and evenly, supporting long-term tissue remodeling rather than a sudden thermal spike.
“We’re aiming for the right amount of heat for the long run of remodeling in a natural way,” Dr. Smith Arayaskul says. “If you do it in the right way, in the right system, you can create the real safety, both in the immediate result and also in the long run for the skin.”
PATIENT EXPERIENCE
What Makes XERF Treatments Noticeably More Comfortable for Patients?
Patient comfort is one of the most underrated factors in treatment success because uncomfortable procedures lead to patients dropping out, spacing sessions too far apart, or dreading follow-ups. Dr. Smith Arayaskul identifies 3 specific design choices in XERF that make a real difference at the treatment table.
- XERF uses the ICD Cooling System that dynamically adjusts cooling levels based on treatment intensity. So instead of a sharp, intense heat, patients feel smooth energy, which makes anesthesia unnecessary and improves the overall patient experience.
- The evenness of XERF’s delivery means patients feel consistent, predictable warmth and not a patchwork of sensations. If energy is hot in one spot and cold in another, that will feel horrible for the patients, according to Dr. Smith Arayaskul.
- Lying for an hour or two gives a different kind of discomfort for patients and doctors. Fortunately, XERF is built differently, providing a genuinely good experience, combining smooth energy, even delivery, and extraordinary session time.
The multiple depth modes of XERF allow Dr. Smith Arayaskul to select the right mode based on where the patient really needs it.
INCLUSIVITY & PERSONALIZATION
How Does XERF Handle Different Skin Types Safely Without Compromise?
Practicing in Bangkok, Dr. Smith Arayaskul treats patients from many ethnic backgrounds and a wide range of skin tones. One of his first points: RF doesn’t discriminate by skin color.
“Radiofrequency is colorblind,” Dr. Smith Arayaskul says plainly. “No matter what skin type you have, you can reach the same results at the same risk of adverse effects, which is very low.”
This feature of XERF is a significant advantage over laser-based skin tightening technologies, which can carry higher risks for darker skin tones.
But the real power of XERF, in his view, goes beyond this baseline safety. XERF has precision and can be personalized. The multiple depth modes of XERF allow him to build a layered treatment plan, selecting the right mode based on where the patient really needs it.
CLINICAL APPLICATION
How Do the Three Depth Modes Actually Translate Into Better Clinical Results?
Dr. Smith Arayaskul is clear: the days of “quick fix” aesthetic treatments are over— at least in his clinic. The three depth modes of XERF directly support this philosophy. By selecting the right mode for the right tissue layer, he avoids wasted energy, something he calls a critical concept in modern aesthetic medicine.
“The selective depth can really make you hit the point with no waste of the shot,” he says. “The right energy, at the right depth, in the right amount, is the key factor to have successful sartorial kind of work, and at the end you will have excellent results with very good, pleasant feelings.”
Dr. Smith Arayaskul compares it to the difference between a tailor who measures precisely and one who cuts by eye. Both might finish a garment. But only one will fit perfectly.
Dr. Smith Arayaskul advises fellow doctors to understand their devices, such as XERF, so they can get exceptional and exquisite results.
CLINICAL COMPARISON
Compared to Other RF and Skin Tightening Technologies, What Has XERF Consistently Delivered?
Dr. Smith Arayaskul has used many RF platforms across his career. He sorts them into a few broad categories: The classic ones are the devices that spread total energy evenly across the face and neck, the second is the one that’s trying to be the first in the market, and the last are the unique ones.
XERF, based on the assessment of Dr. Smith Arayaskul, belongs firmly in the third group. What makes XERF unique is not its power, but its intelligence. He adds that when uniqueness comes to the table, selectiveness will follow, which is very important.
“Selectiveness makes you think during treatment,” Dr. Smith Arayaskul firmly says.
Dr. Smith Arayaskul also mentions the data XERF gives to practitioners in real time. Unlike other devices that only show surface temperature, XERF tracks energy per shot and total accumulated energy delivered, not just heat on the skin.
He also left a piece of advice to his fellow doctors: when they learn to listen and communicate with their devices like XERF, they will surely get exceptional and exquisite results.
BUSINESS STRATEGY
Why Is XERF a Smart Investment for Clinics That Want to Stay Ahead?
In an increasingly crowded market for skin tightening treatments, Dr. Smith Arayaskul says the differentiator is not the device itself, but the level of thinking and personalization. He adds that it is important to learn something from the device because it will make them think further.
Clinics that invest in XERF, Dr. Smith Arayaskul highlights, are not just buying a device. They are investing in a treatment philosophy — one where data, depth precision, and individualized planning set them apart. “The experience lives in the details. And the details will differentiate you from other centers.”
XERF is not just another RF device. Under the guidance of extraordinary practitioners like Dr. Smith Arayaskul, XERF becomes a system for precision thinking, where every depth, every joule, and every pass is a deliberate clinical decision.
For clinics ready to move beyond standard protocols, XERF is the perfect fit.
