If you’re Googling “Ultherapy vs. Thermage FLX,” chances are you’re ready to invest in tighter, younger-looking skin—but without the scalpel. Both treatments are FDA-cleared and popular for non-invasive skin tightening, yet they work very differently under the surface.

Detailed Breakdown
How Ultherapy Works
Ultherapy uses focused ultrasound to stimulate collagen production in the SMAS layer, the same deep tissue layer targeted in surgical facelifts. It delivers precise thermal energy to lift and tighten sagging skin over time. Perfect for patients looking for deeper structural lift—especially along the jawline, neck, and brow.
How Thermage FLX Works
Thermage FLX relies on radiofrequency (RF) technology to heat the collagen-rich layers of the skin, causing immediate contraction and long-term collagen remodeling. It’s best known for smoothing fine lines, wrinkles, and crepey skin, especially around the eyes and mouth. It’s typically more comfortable than Ultherapy and may require fewer post-treatment precautions.
Key Differences That Matter
Depth of Treatment
Ultherapy reaches deeper, which means it’s better for lifting. Thermage focuses more on surface-level tightening and smoothing.
Speed of Results
Thermage shows quicker visible results (often within a month), while Ultherapy takes longer (2–3 months) as collagen production kicks in.
Treatment Comfort
Thermage FLX tends to be less painful, using built-in cooling and vibration tech. Ultherapy, while effective, can be more intense during treatment.
Maintenance & Longevity
Both last around a year, but many clients report Ultherapy’s effects lasting up to 18 months with proper skin care.
Which Is Right for You?
| Skin Concern | Recommended Treatment |
| Jawline sagging | Ultherapy |
| Fine lines around eyes | Thermage FLX |
| Quick results with comfort | Thermage FLX |
| Long-term lifting | Ultherapy |
| Full-face tightening | Combination or consult |
At Cefalù Beauté in Newport Beach, many clients explore combination treatments for the best of both worlds—Ultherapy for the deep lift, and Thermage FLX for smoothing the surface.
Key Takeaways

- Thermage FLX excels at smoothing fine lines and works better on surface-level laxity.
- Both treatments are non-surgical, with zero downtime.
- Ultherapy results are slower but deeper, while Thermage FLX offers faster, gentler tightening.
- The right treatment depends on your skin goals, timeline, and tolerance.
FAQs
1. Is Ultherapy more painful than Thermage FLX?
Yes, Ultherapy typically causes more discomfort due to its deep ultrasound penetration. Most clinics offer numbing options or oral analgesics. Thermage FLX uses a cooling tip and vibration for a more comfortable experience.
2. Can I combine both Ultherapy and Thermage FLX?
Absolutely. Many patients combine the two to get both deep lifting and surface smoothing. A professional consultation will determine the best treatment sequence.
3. How many sessions will I need?
Most people only need one session of either treatment per year. Maintenance varies based on skin condition and age. Some choose a top-up after 6–12 months for optimal results.
4. Are results permanent?
Results aren’t permanent, but they are long-lasting. Ultherapy results may last 12–18 months, while Thermage FLX typically lasts 6–12 months. Ongoing collagen loss due to aging means you’ll eventually need maintenance.
5. Is there downtime or side effects?
There’s zero downtime for both treatments. Some clients may experience mild redness or swelling, which typically resolves in a few hours. Both treatments are safe when performed by qualified professionals.
