Features of Thermage FLX | Differences from Other RF Treatments
Thermage FLX is a leading skin-tightening and facial contouring treatment that utilizes radio frequency (RF) technology. By stimulating collagen production, it helps achieve firmer, more elastic, and youthful-looking skin. Despite being a non-invasive procedure with no incisions, it effectively reduces facial volume and tightens the skin, making it a popular choice for many patients.
Thermage FLX delivers RF energy deep into the dermis and fat layers, promoting collagen contraction and regeneration, which enhances skin firmness and elasticity.
At our clinic, we provide customized treatments tailored to each patient’s unique condition to ensure optimal results. Here, we will introduce the key features of Thermage FLX, along with a comparison to other RF-based treatments.
1Deep Layers Penetration
One of the key features of Thermage FLX is its ability to penetrate deeper layers compared to other RF treatments. It utilizes high-power RF energy, which reaches from the dermis to the fat layer, delivering effective results deep within the skin. This not only stimulates collagen contraction and regeneration but also enhances skin-tightening effects. Additionally, by targeting the fat layer, Thermage FLX provides a more three-dimensional facial contouring effect, making it particularly effective for improving sagging in the cheeks and jawline.

Differences from Other RF Devices
Most other RF treatments are designed primarily to target the dermis, focusing on surface-level skin improvements and collagen production in shallower layers. However, when deeper penetration—from the dermis to the fat layer—is needed, Thermage FLX is the more suitable option. The ability of Thermage FLX to deliver RF energy deeper is a key factor in its superior skin-tightening effects and long-lasting results.
2Unique Cooling Technology
One of the standout features of Thermage FLX is its advanced cooling technology, which protects the skin during treatment. This system cools the skin’s surface while delivering RF (radio frequency) energy, significantly reducing the risk of burns and discomfort. By keeping the surface cool, high-power energy can be effectively delivered to deeper layers without causing unnecessary stress to the skin. As a result, Thermage FLX maximizes skin-tightening effects and collagen contraction/regeneration while minimizing pain and discomfort.

Differences from Other RF Devices
Many other RF devices do not incorporate this type of cooling technology, which increases the risk of heat damage to the skin. This can be particularly concerning for individuals with sensitive or thin skin, as they may be more prone to burns, redness, or irritation. In contrast, Thermage FLX ensures both safety and effectiveness, making it a comfortable and highly efficient RF treatment thanks to its integrated cooling system.
3Immediate and Long-Lasting Effects
Thermage FLX is widely recognized as an RF treatment that provides both immediate and long-lasting results. Right after the procedure, patients can experience instant skin-tightening effects due to collagen contraction, making it an ideal treatment for those with upcoming special events or important occasions. However, the true benefit of Thermage FLX lies in its ability to enhance results over the following months.
The high-frequency energy delivered by Thermage FLX continuously stimulates collagen production in the deeper layers of the skin, leading to improved firmness and elasticity over time. As a result, the effects can last from six months to a year. Unlike other RF treatments that require frequent sessions, Thermage FLX offers long-lasting results with just a single treatment, making it an excellent choice for busy individuals or those who prefer fewer clinic visits.
Differences from Other RF Devices
Other RF treatments are a great option for those seeking short-term results. These treatments mainly target the dermis, stimulating collagen production in the upper skin layers. This allows for immediate improvements in skin firmness and fine lines, which is a key advantage.
However, the effects of these treatments tend to be shorter-lived, typically lasting only one to several months, requiring frequent sessions to maintain results. While regular treatments can help improve skin texture and provide a lifting effect, they require consistent clinic visits. In contrast, Thermage FLX is ideal for those who want long-lasting benefits with fewer treatments, whereas other RF treatments are better suited for short-term care and targeting the skin’s surface layers.
What is Thermage FLX?

Thermage FLX is the latest model of the globally popular skin-tightening, facial contouring, and anti-sagging treatment, performed in over 80 countries. Introduced in 2018, this advanced version offers a significantly shorter treatment time and reduced discomfort compared to previous models.
By delivering radio frequency (RF) energy, Thermage FLX stimulates collagen production, providing an immediate tightening effect after the procedure, with results that can continue to improve for six months to a year.
About RF High Radio Frequency Treatment

This is a skin treatment method that uses high frequency waves to heat the inside of the skin using frictional heat between water molecules and contract collagen, tightening the skin and improving sagging and wrinkles.

It also reaches the superficial layers, making it beneficial for enhancing skin elasticity and reducing fine lines. This treatment is especially ideal for those who want to tighten their skin while improving texture and reducing volume.
Comparison with Other Treatments
Thermage FLX
Targets the fat and dermal layers, specializing in skin tightening, facial contouring, and improving skin texture.

Ulthera
Approaches the deep SMAS layer, offering results similar to a surgical facelift. It is highly effective for lifting and treating sagging skin.

Achieve the Ultimate Lifting and Facial Contouring Treatment with Thermacool FLX and Ulthera Combination

For those seeking lifting, tightening, and facial contouring effects, the combination of Ulthera and Thermage FLX is an ideal treatment. Since each treatment targets the skin in different ways, using them together results in more effective lifting, tightening, and facial contouring.
Benefits of Combining Treatments
-
1Lifting × Tightening
Ulthera lifts sagging from the deeper layers, while Thermage FLX tightens the superficial layers of the skin. Together, they improve sagging and achieve facial contouring in a single treatment.
-
2Immediate Results and Long-lasting Effects
Both Ulthera and Thermagel FLX show immediate results after the treatment, with peak effects occurring 1-2 months later. The results last for approximately 6 months to 1 year.
-
3Skin Texture Improvement and Rejuvenation
The tightening and facial contouring effects of Thermagel FLX further enhance the lifting effects of Ulthera, improving skin texture and providing rejuvenation.
Treatment Flow
When combining Thermage FLX and Ulthera, the treatment is performed in the following steps. First, Ulthera is used to improve sagging from the fat layer to the SMAS layer (muscle fascia). Afterward, Thermage FLX is applied to target the dermal and fat layers to tighten the skin. This combination maximizes the synergistic effects of lifting and tightening, while also improving skin texture, firmness, and smoothness.
