They’re three different energies aimed at three different depths. Ultherapy uses focused ultrasound to heat tissue at set depths, including 4.5mm, which reaches the layer a surgeon tightens — it’s the deepest and the most uncomfortable. Thermage uses monopolar radiofrequency to heat a broader, shallower volume, so it’s better on crepe and skin quality than on lift. Sofwave uses ultrasound at a fixed mid-depth of about 1.5mm, which makes it gentler and quicker with a milder result. Depth is the whole story: deeper reaches structure, shallower improves surface.
The short version
| Treatment | Energy | Depth | Typical cost | What it’s best at |
|---|---|---|---|---|
| Ultherapy | Microfocused ultrasound | 1.5, 3.0 and 4.5mm | ~$2,500–$4,500 | The most lift available without surgery, on mild to moderate laxity. The most painful of the three |
| Thermage | Monopolar radiofrequency | Broad, roughly 2–3mm | ~$2,000–$4,000 | Skin quality, crepe and overall smoothing over a large area. Comfortable, one long session |
| Sofwave | Ultrasound, fixed depth | ~1.5mm | ~$1,500–$3,500 | A gentler, faster mid-depth option. Less dramatic, far more tolerable, good on early laxity |
Why depth decides everything
All three work the same way in principle. Deliver controlled heat into tissue, injure it just enough, let the body respond by making new collagen over three to six months. What separates them is where that heat lands.
Skin is layered, and each layer does a different job. The epidermis at the top is surface. The dermis below it, roughly 1 to 3mm down, is where collagen and elastin live — treat here and you improve texture, crepe and firmness. Below that sits fat and then the SMAS, the fibrous sheet at around 4 to 5mm that supports the whole structure of the face. That’s the layer a facelift tightens.
So a device that reaches 1.5mm can make your skin better. A device that reaches 4.5mm can, modestly, move it. Neither is superior in the abstract, but they answer different complaints, and picking by brand recognition rather than by depth is how people end up with an expensive result they don’t notice.
Ultherapy: the deep one
Focused ultrasound, delivered at three depths, with an ultrasound image showing the provider what’s under the applicator before the energy fires. That imaging is the feature worth caring about — it means placement is deliberate rather than assumed.
It’s the only one of the three that consistently reaches the SMAS, which is why it’s the one with a genuine lifting claim. Published work reports modest but measurable improvement in brow position and jawline definition. Modest is the operative word; the galleries oversell it badly.
It also hurts. Not uncomfortable, not warm — a deep, sharp, intermittent pain along the jaw and brow where the applicator sits near bone. Providers who keep you comfortable by lowering the energy are also lowering your result, which is a trade worth discussing openly beforehand. There’s no downtime beyond a few days of tenderness.
Thermage: the broad one
Monopolar radiofrequency heats a wider, shallower volume of tissue in one pass, with a cooling burst on the surface so the epidermis is protected while the dermis gets warm. It covers ground quickly, which makes it the practical option for larger areas and for bodies as well as faces.
What it’s genuinely good at is skin quality. Crepe, fine texture, a general tightening of the surface. It’s often described as a lifting treatment and that’s a stretch — the depth isn’t there for it. Think of it as making the fabric better rather than taking the fabric in.
Comfort is much better than Ultherapy, closer to a hot snap than a deep ache, and newer handpieces with vibration have improved that further. It’s one long session rather than a course.
Sofwave: the gentler one
Newer, and often positioned as the compromise. Ultrasound again, but at a single fixed depth of roughly 1.5mm, delivered across a wider array rather than in focused columns. It’s cleared for lifting the brow and improving lines on the neck and under the chin.
The result is milder and the experience is much easier — most sessions run 30 to 45 minutes, and the discomfort is manageable with topical numbing alone. Because it stays in the dermis it doesn’t carry the fat-atrophy concern that deeper treatments occasionally do.
It suits someone earlier in the process: skin that’s beginning to lose firmness rather than skin that has loosened. If you’d be a marginal Ultherapy candidate because there isn’t much laxity yet, this is the more sensible spend, and the cheapest of the three.
What a session is like
Ultherapy starts with mapping. The provider marks a grid on your face, applies gel, then works the applicator line by line, firing energy at each pass. You feel it as a deep, hot prickle that comes in bursts, worst along the jaw and the brow. Numbing cream helps a little; many providers also offer a nerve block or oral pain relief, and it’s fair to ask about both beforehand rather than discovering the answer at 4.5mm. Forty-five to ninety minutes depending on areas. Afterward you’re pink and tender and can go back to work.
Thermage is a different sensation entirely: repeated cycles of cooling, then a wave of heat, then cooling again. It’s warm rather than sharp, and the feedback loop is part of the technique — the provider adjusts based on what you report, so being honest about the heat matters. One long session, often 90 minutes for a full face, and you leave slightly flushed.
Sofwave sits between them and closer to Thermage on comfort. Topical numbing, a gliding applicator, a warm pressure that builds over each pass. Thirty to forty-five minutes for a face, mild redness afterward, nothing anybody would notice by evening.
In all three, the visible change on the day is swelling rather than result, and it settles within a week. Judging any of them before three months is judging the wrong thing.
The maintenance nobody quotes
Every one of these is a subscription described as a purchase. A result that peaks at six months and holds for a year or so means rebooking somewhere between twelve and eighteen months out, indefinitely, if you want to stay where you landed.
Annualized, all three land in much the same band, and it’s a fair price for what they do and a poor one if you were budgeting a single event. It also changes the comparison with the cheap end of the market: five years of sunscreen, a retinoid and a microcurrent habit costs a fraction of one round, and it’s the groundwork that makes the expensive version work better when you do book.
If I Were You
If your jawline is softening and nothing is hanging yet Ultherapy is the one with the depth to matter. Ask to see the imaging, and ask what energy settings they plan to use.
If your complaint is crepe rather than looseness Thermage. Depth won’t help you and coverage will.
If you’re in your late thirties and firmness is just starting to go Sofwave, or nothing yet. Deep energy on skin that hasn’t loosened is money spent early.
If you’re afraid of pain be honest about it at the consultation. Sofwave and Thermage are both far more tolerable, and a treatment you abandon halfway is worse value than a gentler one completed.
If you’re thin-faced or have lost volume none of these is your answer, and tightening deflated skin can make it read older. Sort out laxity versus volume loss first.
If the budget is a few hundred rather than a few thousand put it into skin quality. That’s not a consolation prize, it’s the thing that decides how well you respond if you treat later.
What none of them will do
Replace a facelift. All three are marketed against surgery and none of them competes with it. Surgery removes and repositions tissue; energy devices ask existing tissue to remodel. If there’s real descent, the honest conversation is with a plastic surgeon, even if you don’t want the operation, so you know what the alternatives really are.
Work on volume. Hollowing is a filler and fat question, not a heat question.
Last indefinitely. Results peak at three to six months and hold for something like a year to eighteen months, then aging resumes from there. Anyone quoting a permanent result is quoting a marketing line.
Any of this depends on provider skill more than brand. The same device produces very different outcomes in different hands, and complications — bruising, temporary numbness, rarely nerve irritation or localised fat loss — track with technique. Talk to a board-certified dermatologist or plastic surgeon, and treat this article as background rather than advice.

How we picked what to say
Depth and energy type were treated as the organising facts, because they’re the physical constraints and everything else is positioning. Published clinical literature was weighted over manufacturer galleries, which are lit and posed and consistently imply surgical results. Cost figures are typical US ranges and vary widely by city and provider; treat them as a shape rather than a quote. Comfort was included as a first-class criterion rather than a footnote, because tolerance determines the energy that gets delivered, and energy delivered determines the result.
FAQ
Can you combine them?
Providers do, often Ultherapy for depth and Thermage for surface, spaced out rather than the same day. It’s a real strategy and a real doubling of cost. Discuss sequencing with your provider.
How soon will I see anything?
Six weeks at the earliest for all three, peaking around three to six months. Anything visible the next day is swelling.
Is one safer than the others?
All three have good safety records in trained hands. Deeper treatments carry a slightly higher risk of temporary nerve irritation and, rarely, localised fat loss. Ask any provider directly about their own complication history.
What about radiofrequency microneedling?
Different category — it adds a mechanical injury to the heat and reaches the dermis through needles. It’s covered in the radiofrequency explainer.
Do results last longer if I keep treating?
Maintenance holds you nearer your best result rather than compounding it. Patients who like the outcome rebook at twelve to eighteen months.
The bottom line
Pick by depth and by what’s actually bothering you, not by which name you’ve heard. Deep laxity that hasn’t yet become descent is Ultherapy’s window. Crepe and surface quality is Thermage. Early firmness loss, or a low pain threshold, is Sofwave. And if you’re not sure which of those describes you, the guide to non-surgical tightening starts from the beginning. More in Skin.
