Get to know the Ultherapy Prime and Thermage FLX skin tightening devices.
What is the Ultherapy Prime skin tightening device?
Ultherapy Prime is a skin tightening device developed by Merz Aesthetics from the advanced Ulthera SPT technology. It utilizes Microfocused Ultrasound with Visualization (MFU-V), or targeted high-frequency sound waves, combined with a real-time visualization system to deliver heat energy deep into the SMAS (Superficial Muscular Aponeurotic System) layer, the same skin layer targeted by surgeons during facelift surgery.
A key highlight of the Ultherapy Prime skin tightening device is its 35% larger Full HD screen, allowing doctors to accurately visualize skin layers and adjust energy levels specifically for each individual's needs. Furthermore, the processing speed is 20% faster, shortening treatment times and minimizing discomfort during the procedure.
The Ultherapy Prime skin tightening device delivers energy at multiple depths: 1.5 mm, 3.0 mm, and 4.5 mm, covering both superficial and deep layers. This stimulates the production of new collagen and elastin, resulting in firmer, tighter skin, lifted jawline, cheeks, chin, eyebrows, and the area around the eyes. It's also suitable for sensitive skin areas such as under the eyes, lips, and forehead. Results become noticeable within 2-3 months and last approximately 1-2 years, with no downtime or surgery required.
What is the Thermage FLX skin tightening device?
Thermage FLX skin tightening device is a lifting technology that uses Monopolar Radiofrequency (RF) energy, or high-frequency radio waves, to deliver heat to the dermis and subcutaneous fat layers. This stimulates the production of new collagen and causes existing collagen to contract, resulting in firmer and smoother skin.
The standout feature of the Thermage FLX skin tightening device is its ability to evenly distribute heat energy, making it ideal for those seeking to address sagging skin across the face, including areas such as the cheeks, neck, under-eyes, and corners of the mouth. It also helps reduce wrinkles, leaving the skin softer and healthier-looking. Importantly, Thermage FLX is a non-surgical treatment; it leaves no scars and requires no downtime.
After the procedure, patients will see some results, and the full results will gradually become more apparent over 2-6 months. The results will last approximately 1-2 years, depending on skin condition and post-procedure care.

Operating principles and energy depth.
- Ultherapy Prime skin tightening device
The Ultherapy Prime skin tightening device uses microfocused ultrasound technology to deliver heat energy deep into the SMAS layer, the underlying tissue structure that surgeons use for facelifts. A key feature of Ultherapy Prime is its real-time visualization screen, which allows doctors to clearly see the skin layers and precisely target energy according to each individual's skin condition. This results in high efficacy and reduces the risk of surgical errors.
- Thermage FLX skin tightening device
The Thermage FLX skin tightening device uses monopolar radio frequency (RF) waves to deliver heat to the dermis and subcutaneous fat layers, stimulating the contraction of old collagen and accelerating the production of new collagen. A key advantage of Thermage FLX is its ability to treat the entire face, not just specific areas, making it suitable for those who desire smoother and firmer skin in all dimensions.
Expected results
- Ultherapy Prime skin tightening device
The Ultherapy Prime skin tightening device delivers outstanding results in deep lifting, helping to define facial contours, address excess fat such as sagging cheeks and double chin, lift eyebrows, reduce sagging around the eyes, and improve skin elasticity and firmness.
- Thermage FLX skin tightening device
The Thermage FLX skin tightening device focuses on firming the skin and reducing wrinkles, especially in areas with fat accumulation such as under the chin, cheeks, and corners of the mouth. After treatment, the skin feels smoother and continues to improve as collagen production is fully restored, boosting confidence for those concerned about wrinkles and sagging skin across the face.
Time to see results after treatment
- Ultherapy Prime skin tightening device
After Ultherapy Prime skin tightening treatment, partial results of 20–30% are visible from the first session. This is because collagen needs time to regenerate, which usually takes about 2-3 months to see full lifting results. The advantage is that once results are achieved, they last a long time, so frequent treatments are not necessary.
- Thermage FLX skin tightening device
With Thermage FLX, you'll see some immediate changes, such as slightly tighter skin, but noticeable changes will gradually appear within 2-3 months as the body needs time to produce new collagen.
Duration of time the results last
- Ultherapy Prime skin tightening device
The results from Ultherapy Prime skin tightening treatment last approximately 1-2 years, making it a worthwhile investment as it doesn't require frequent repeat treatments and effectively helps slow down skin aging.
- Thermage FLX skin tightening device
Thermage FLX skin tightening treatment provides results lasting approximately 1-2 years, depending on skin condition, age, and post-treatment self-care such as moisturizing cream application, sun avoidance, and a diet that benefits the skin.
Sensations during the procedure.
- Ultherapy Prime skin tightening device
During Ultherapy Prime treatment, patients typically feel heat penetrating the deeper layers of the skin, especially in areas with thin skin, such as the jawline and under the chin. Therefore, a numbing cream is usually applied or administered before the procedure to alleviate the sensation of discomfort.
- Thermage FLX skin tightening device
Thermage FLX produces a warm sensation on the skin; you may feel slight heat and tightness. The vibration in the device head helps to minimize pain or discomfort, allowing patients to relax more during the procedure.
Duration of each session.
- Ultherapy Prime skin tightening device
The time required depends on the area being treated, but generally it takes around 60-90 minutes, which is suitable for those who want a quick result and don't want to spend a lot of time.
- Thermage FLX skin tightening device
Thermage FLX skin tightening treatment takes slightly longer, averaging 90-120 minutes, because it requires delivering energy to multiple areas thoroughly for even skin tightening.

Can I have Ultherapy Prime and Thermage FLX skin tightening treatments done simultaneously?
Can I have Ultherapy Prime and Thermage FLX skin tightening treatments done simultaneously?
- In general, it is not recommended to have Ultherapy Prime and Thermage FLX skin tightening treatments on the same day, as the two technologies use different energy levels and affect the skin at different layers. Doing both simultaneously may increase the risk of skin irritation or other side effects. For best results, a waiting period of 1-3 months is recommended, or consult a doctor to plan a suitable treatment based on your skin condition and individual needs.

Which skin tightening device is better, Ultherapy Prime or Thermage FLX?
Which skin tightening device is better, Ultherapy Prime or Thermage FLX?
- Both Ultherapy Prime and Thermage FLX have their own unique advantages, suitable for different skin problems and needs. If you focus on deep skin tightening, defining the facial contours, or lifting sagging eyebrows, Ultherapy Prime is more suitable because its ultrasound energy can penetrate to the SMAS layer, the same layer surgeons use for facelifts. Thermage FLX, on the other hand, addresses concerns about loose, sagging skin and subcutaneous fat accumulation, such as in the cheeks and chin, because its radiofrequency waves tighten the dermis and subcutaneous fat, resulting in firmer, smoother skin.
Are the Ultherapy Prime and Thermage FLX skin tightening devices different in terms of pain?
- Generally, those undergoing Ultherapy Prime skin tightening will feel more heat under the skin because the energy waves are focused deep into the SMAS layer. In contrast, Thermage FLX provides a warm sensation on the surface and uses vibrations and a cooling system to reduce discomfort, resulting in less pain than Ultherapy Prime. However, both methods typically involve the application of a numbing cream before treatment to help minimize discomfort during the procedure.
Can I have Ultherapy Prime skin tightening treatment followed by Thermage FLX?
- You can have Thermage FLX skin tightening treatment after Ultherapy Prime, but it's recommended to wait at least 1-3 months to allow the skin to fully recover and for the results of Ultherapy Prime to become clearly visible. It's essential to consult a doctor to assess your skin condition and plan a treatment tailored to your individual needs for optimal and safe results.
In summary, choosing the right skin tightening device for you: Ultherapy Prime or Thermage FLX.
Ultherapy Prime and Thermage FLX are both popular skin tightening technologies, and while they aim to address sagging skin, they differ in their mechanism of action, results, and suitability for different skin types.
The choice between Ultherapy Prime or Thermage FLX skin tightening depends on the skin concerns, desired results, and individual suitability. There is no single best technology for everyone; each method has unique advantages that address different needs.
For comprehensive results encompassing both deep skin firmness and superficial skin smoothness, consider combining both technologies for an appropriate duration under the supervision of a physician. This ensures safe and effective results.
Ultimately, consulting a doctor to assess your skin condition and plan a personalized treatment is key to choosing the right and most worthwhile method for your long-term beauty investment.
