Aging skin is a natural journey, but modern aesthetic technology offers more ways than ever to restore a youthful glow. While classic treatments remain effective, new innovations like Xerf and OligioX have entered the market, offering enhanced comfort and deeper precision.
In this article, we compare these procedures to help you determine which one is right for your unique skin goals.
Xerf (Dual-Frequency Monopolar RF)
Xerf is the latest breakthrough in structural skin tightening, utilizing a world-first dual-frequency system to address both the dermis and the deeper facial ligaments.
Benefits
-
Structural Lifting: Unlike standard RF, Xerf’s 2 MHz frequency reaches the Retinacular Cutis (vertical retaining ligaments), providing a foundational lift that anchors the skin more effectively.
-
Superior Comfort (Never-Numb™): Optimized energy delivery means most patients do not require numbing cream. The treatment is described as a warm, comfortable sensation rather than the sharp “rubber band snap” associated with older technologies.
-
High-Efficiency Skin Density: The 6.78 MHz frequency focuses on the dermis, significantly increasing collagen and elastin production for a “thicker,” more resilient skin texture.
-
Intelligent Surface Protection: The Integrated Cryogen Delivery (ICD) system monitors skin temperature millisecond-by-millisecond, blasting cool air to protect the epidermis while the deep layers reach therapeutic heat.
-
No Downtime: Patients can immediately apply makeup and return to their daily routine with zero “recovery” period.
Drawbacks
-
Gradual Results: While some immediate tightening occurs due to collagen contraction, the full structural lifting effect takes 2–3 months to develop as new collagen matures.
-
Premium Cost: As a new, high-end technology, the cost per session is typically higher than standard HIFU or older RF devices.
-
Newer to Market: While clinically proven, it does not yet have the 20-year longitudinal data history that legacy brands like Thermage possess.
-
Requires Maintenance: To maintain the structural integrity of the ligaments, annual or bi-annual “touch-up” sessions are generally recommended.
OligioX
OligioX is the premium evolution of the original Oligio system. It utilizes high-powered Monopolar Radiofrequency (RF) at 400W to deliver volumetric heating into the dermis. Unlike older RF devices, it is optimized for the specific dermal density of Asian skin, focusing on both “slimming” the face and creating a “Glass Skin” glow.
Benefits
-
Dual-Wave “GXG” Technology: This proprietary system allows the machine to deliver energy in two distinct modes. It tightens existing collagen for an instant 20–30% lift while simultaneously triggering long-term neocollagenesis (new collagen growth).
-
Superior Comfort (OSCA™ Technology): One of the biggest drawbacks of traditional RF is the “stinging” pain. OligioX solves this with a redesigned 11-pulse cooling system and a vibration mechanism that “distracts” the nerves, making it virtually painless for most patients.
-
Fat Reduction & Contouring: Beyond tightening, the volumetric heat helps break down minor subcutaneous fat cells. This makes it ideal for reducing jowls, double chins, and “chubby” cheeks to achieve a sharper V-shape.
-
The “Glass Skin” Effect: Because it stimulates collagen in the upper and mid-dermis, patients report significantly smaller pores, smoother skin texture, and a natural radiance that topical skincare cannot achieve.
-
Zero Downtime: You can apply makeup and return to work immediately. Unlike injections, there is no risk of bruising or swelling.
The Drawbacks
-
Not a “Surgical” Fix: While excellent for mild to moderate sagging, OligioX cannot replace a surgical facelift for patients with severe skin laxity.
-
Maintenance Required: To maintain the structural integrity and glow, sessions are typically recommended every 8–12 months. It is not a “permanent” solution.
-
Collagen Dependency: Since the result relies on your body’s ability to produce new collagen, results may be less dramatic for smokers or those with high-stress lifestyles/poor nutrition.
-
Specific Contraindications: It is not suitable for individuals with pacemakers, metallic implants in the treatment area, or those who are pregnant.
Stem Cell Therapy
Stem cell therapy is a relatively new cosmetic procedure that involves the use of stem cells to help rejuvenate the skin. Stem cells are special cells that have the ability to regenerate and repair damaged tissue. In stem cell therapy, stem cells are injected into the skin to help stimulate the production of new collagen and elastin, which can help improve the texture and firmness of the skin.
Benefits
- Natural Procedure: Stem cell therapy is a natural procedure that uses the body’s own cells to achieve its results, which may be appealing to patients who prefer a more natural approach to cosmetic treatments.
- Customizable Treatment: Stem cell therapy can be customized to meet the specific needs of each patient, making it a highly personalized procedure.
- Long-Lasting Results: Stem cell therapy can provide long-lasting results, with some patients seeing improvements for up to two years.
- Potential Health Benefits: Some research suggests that stem cell therapy may have potential health benefits beyond cosmetic improvements, such as reducing inflammation and promoting tissue repair.
Drawbacks
- Limited Availability: Stem cell therapy is not widely available in all countries and regions, and may be difficult to access for some patients.
- Cost: Stem cell therapy can be expensive, with prices ranging from several thousand to tens of thousands of dollars per session.
- Risks and Side Effects: While stem cell therapy is generally considered safe, there is some risk of infection, bleeding, and other side effects.
- Results May Vary: Results can vary from patient to patient, and some patients may not see the same level of improvement as others.
Ulthera
Ulthera, also known as ultrasound therapy, is a non-invasive cosmetic procedure that uses ultrasound waves to stimulate the production of collagen and elastin in the skin. Ulthera is often used to treat sagging skin on the face and neck, as well as fine lines and wrinkles.
Benefits
- Non-Invasive: Ulthera is a non-invasive procedure that does not require any incisions or surgery.
- Little to No Downtime: Ulthera typically has little to no downtime, with most patients able to return to their normal activities immediately after the procedure.
- Long-Lasting Results: Ulthera can provide long-lasting results, with some patients seeing improvements for up to two years.
- Customizable Treatment: Ulthera is a customizable treatment that can be tailored to meet the specific needs of each patient, making it a highly personalized procedure.
Drawbacks
- May Require Multiple Sessions: Ulthera may require multiple sessions to achieve optimal results.
- Cost: Ulthera can be expensive, with prices ranging from several hundred to several thousand dollars per session.
- Discomfort: Some patients may experience mild discomfort during the procedure, although this is generally well-tolerated and can be managed with medication.
- Results May Vary: Results can vary from patient to patient, and some patients may not see the same level of improvement as others.
Thermage
Thermage is a non-invasive cosmetic procedure that uses radiofrequency energy to heat the deep layers of the skin, stimulating the production of collagen and elastin. Thermage is often used to treat sagging skin on the face and body, as well as fine lines and wrinkles.
Benefits
- Non-Invasive: Thermage is a non-invasive procedure that does not require any incisions or surgery.

Which is Right for You?
Choosing the right treatment is no longer about finding the “best” machine; it is about identifying which anatomical layer of your face requires the most attention. Modern aesthetic medicine focuses on a “layered” approach to ensure every concern—from deep muscle sagging to surface texture—is addressed.
Here is a clinical breakdown to help you determine which technology aligns with your goals.
1. The “Foundation Lift”: Ulthera or HIFU
Best for: Lifting deep sagging, sharpening the jawline, and heavy jowls.
If your primary goal is to “pull everything up,” you need to target the SMAS layer. This is the deep muscle foundation that acts as the scaffolding for your face.
-
The Profile: You have significant skin laxity, a blurred jawline, or drooping brows.
-
The Choice: Ulthera is the gold standard for foundational lifting. Because it includes DeepSee™ real-time imaging, the clinician can visualize your tissue layers to deliver energy precisely. HIFU is a versatile, often more budget-friendly alternative that is particularly effective for reducing stubborn fat in the lower face while providing a moderate lift.
2. The “Structural Anchor”: Xerf
Best for: Structural firming, skin thinning, and those who are pain-sensitive.
Xerf represents the new frontier in “structural tightening.” It doesn’t just treat the skin; it targets the Retinacular Cutis—the vertical ligaments that anchor your skin to your facial structure.
-
The Profile: You feel your skin is becoming “detached” or loose, but you aren’t ready for surgery. You want a deep result but are afraid of the pain associated with traditional lifting procedures.
-
The Choice: Its unique Dual-Frequency RF ($2 MHz$ and $6.78 MHz$) allows for deeper structural tightening. Most importantly, it is designed for maximum comfort, often requiring no numbing cream at all.
3. The “Contour & Glow”: OligioX
Best for: Face slimming, V-shape contouring, and refining “Glass Skin” texture.
OligioX is the rising star for those who want that refined, high-definition aesthetic. It focuses on the mid-to-deep dermis.
-
The Profile: You want a sharper V-shape, you want to reduce minor cheek fat, and you want your skin to look smaller-pored and radiant.
-
The Choice: Optimized specifically for Asian skin density, its G-Mode (Gentle yet Powerful) “shrink-wraps” the skin and melts small fat pockets, while its vibration system ensures a very comfortable experience.
4. The “Surface Smoother”: Thermage FLX
Best for: Crepey skin, fine wrinkles, and eyelid tightening.
Thermage remains the global powerhouse for horizontal “bulk heating” and skin smoothing.
-
The Profile: You have “pinchable” loose skin, fine lines around the eyes (Thermage Eyes), or a “wavy” skin texture on the face or body.
-
The Choice: It is the benchmark for horizontal tightening. It “shrink-wraps” the skin, making it look smoother, flatter, and more compact.
5. The “Cellular Health” Boost: Stem Cell Therapy
Best for: Biological repair, skin brightness, and overall thickness.
Unlike the machines above, this is a biological intervention. It’s about the “health of the soil,” not just the “tightness of the fence.”
-
The Profile: Your skin looks tired, dull, or translucent. You want to improve the actual biological age of your skin cells rather than just heating them.
-
The Choice: This treatment uses growth factors to wake up your skin’s regenerative powers. It is the perfect foundational treatment to combine with any energy-based machine to ensure your skin has the “fuel” it needs to produce new collagen.
Summary Comparison Table
| Primary Concern | Recommended Treatment | Action Layer | Pain Level |
| Deep Sagging / Jowls | Ulthera / HIFU | SMAS (Deepest) | Moderate |
| Loose Ligaments / Firming | Xerf | Retinacular Cutis | Very Low |
| Chubby Cheeks / Texture | OligioX | Deep Dermis + Fat | Very Low |
| Crepey Skin / Smoothing | Thermage FLX | Mid Dermis | Moderate |
| Dullness / Aging Cells | Stem Cell Therapy | Cellular Level | Injectable |
The Verdict
The most transformative results rarely come from a single machine. At Siam Clinic, we find that a “Hybrid Protocol” such as using HIFU for the foundation and OligioX or Xerf for the structural finish provides the most natural and long-lasting rejuvenation.

Q&A
Q: How do I know if I need Ultrasound (Ulthera) or Radiofrequency (Xerf/OligioX)?
A: Think of it as Lifting vs. Tightening. If your skin feels heavy and is sagging downward (jowls, drooping brows), you likely need the deep Ultrasound power of Ulthera to target the SMAS layer. If your skin feels “thin,” “empty,” or has lost its “snap” (crepey texture), Radiofrequency like Xerf or OligioX is better for building dermal density and “shrink-wrapping” the surface.
Q: Can I combine Xerf and OligioX in the same session?
A: While both are Monopolar RF, they serve slightly different roles. Xerf targets the structural ligaments, while OligioX focuses on surface glow and contouring. At Siam Clinic, we find that a “Hybrid Protocol” often yields the best results—using different devices to target different depths of the face in a single, comprehensive plan.
Q: Why is Xerf advertised as “pain-free” compared to Thermage?
A: Xerf utilizes Wave Fit™ technology, which delivers energy in pulses that match the skin’s natural impedance, combined with a highly advanced cooling system. This prevents the “heat spike” that causes pain in older RF generations. Most patients describe it as a warm sensation rather than a sharp sting.
Q: How long does it take to see results from Stem Cell Therapy?
A: Unlike energy-based machines that offer some instant contraction, Stem Cell Therapy is a biological process. You may notice an “inner glow” within 2 weeks, but the peak results for skin firmness and health typically appear at the 3-to-6-month mark as your body builds new, healthy tissue.
Q: Will these treatments make my face look “unnatural” or “frozen”?
A: Not at all. Because all these modalities (Ulthera, Xerf, OligioX, Thermage) work by stimulating your own body’s collagen, the results are entirely natural. You are simply “reversing” the clock by restoring the structural proteins you had years ago. There are no foreign substances involved, unlike fillers or neurotoxins.
