They are not competitors — they are complements
Patients frequently ask: “Which is better — Ultherapy or Thermage?” This question assumes the two devices do the same thing. They do not.
Each device works on a different tissue layer, produces a different type of response, and is suited for a different clinical scenario. Choosing between them is not like choosing between two restaurants. It is more like choosing between a foundation repair and a surface refinish.
How each device works
Ultherapy (Micro-focused Ultrasound)
- Target layer: SMAS (4.5mm) and deep dermis (3.0mm, 1.5mm)
- Mechanism: Creates thermal coagulation points at precise depths
- Best for: True lifting — particularly jawline, submental area, and brow
Ultherapy is the only non-surgical device cleared by the FDA for lifting. It reaches the SMAS layer, which is the same layer surgeons address during a facelift. This is why it produces actual lift rather than just tightening.
Thermage FLX (Radiofrequency)
- Target layer: Dermis and subdermis (bulk heating)
- Mechanism: Volumetric radiofrequency that heats collagen broadly
- Best for: Skin tightening, texture improvement, mild laxity
Thermage is better understood as a tightening and remodeling tool. It does not reach the SMAS layer, so it does not produce the same structural lift as Ultherapy. But for patients whose main issue is skin laxity rather than deep sagging, it can be remarkably effective.
Oligio (High-Intensity Focused Ultrasound)
- Target layer: Similar depth targeting as Ultherapy but with a broader energy spread
- Mechanism: HIFU with larger treatment zones
- Best for: Overall firming, patients who want broad coverage with moderate downtime
How we decide at Tune Clinic
The decision is not based on which machine is “newest” or “most popular.” It is based on a diagnostic assessment:
| Primary concern | Likely first choice | Why |
|---|---|---|
| Jawline sagging | Ultherapy | Reaches SMAS layer for structural lift |
| Loose skin, fine lines | Thermage FLX | Broad dermal tightening |
| Overall firmness | Oligio or combination | Moderate depth, broad coverage |
| Deep sagging + loose skin | Ultherapy + Thermage | Layer-by-layer approach |
“The best lifting device is the one that matches the layer causing the problem. Not the one with the best marketing.”
What about combining devices?
Combination protocols are often more effective than single-device approaches. At Tune Clinic, we frequently combine Ultherapy (deep structural lift) with Thermage (surface tightening) in a single session or staged plan. This is the core logic behind our Signature Lifting protocol.
The key is sequencing: deep first, surface second. Not the other way around.
