Ultherapy Prime and Sofwave are both ultrasound treatments. Neither involves an incision, and downtime varies by person. So the question follows naturally: which one should I have?
The honest answer begins with where each one sends its energy. They use the same kind of energy, but deliver it to different depths and in different shapes. This piece sets them side by side — not to rank them, but to show where each one comes to rest.
Depth, first. Ultherapy Prime delivers focused ultrasound at set depths beneath the skin; transducers of 1.5, 3.0, and 4.5 mm are available. Sofwave, according to its manufacturer, keeps most of its thermal effect between 0.5 and 2 mm within the dermis, centered at about 1.5 mm, with built-in cooling.
Shape is the second difference. Ultherapy Prime gathers ultrasound to focused points at the depths your doctor selects. Sofwave fires several parallel beams that deposit energy across a broader area. One is chosen for depth; the other for breadth within a single layer. In Korea, Ultherapy Prime is approved for lifting the eyebrow, the sagging jawline, and the upper chest and improving décolletage wrinkles, while Sofwave is approved for improving wrinkles on the cheeks, chin, eyebrows, and neck (for people aged 22 and over).
Ultherapy Prime delivers focused ultrasound in lines beneath the skin. Transducers with treatment depths of 1.5, 3.0, and 4.5 mm are available, and depth and energy level are set individually for each treatment area.
Ultrasound imaging lets your doctor visualize the dermal and subdermal layers before energy is delivered, to confirm coupling of the transducer and the treatment depth.
It comes up in consultation for mild to moderate laxity around the jawline and for early signs of jowl or brow drooping. Session length depends on the areas planned. Use on the neck or other areas is outside the approved purpose · at the doctor's discretion.
Sofwave uses SUPERB — Synchronous Ultrasound Parallel Beam technology, the manufacturer's term. Parallel ultrasound beams deliver energy to the mid-dermis; the manufacturer states that most of the thermal effect stays between 0.5 and 2 mm within the dermis, centered at about 1.5 mm. Surface cooling is built into the handpiece.
By heating this layer in zones, it may help smooth fine lines in the treated area; individual results vary. A session takes about 30 to 45 minutes.
It comes up when fine lines and wrinkles on the cheeks, chin, brow, or neck are the concern.
Downtime varies by person. After Ultherapy Prime, mild redness, swelling, tingling, tenderness, or bruising may occur; any tenderness or swelling may ease within days, and many people resume normal routines the same day.
After Sofwave, many people return to daily life right away, though this varies by person. Mild redness usually settles on its own, and throbbing pain may occur; contact us if it lasts longer than expected.
After either, a cold compress is fine. If white lines appear, a cold compress may help, and they usually settle within two to four hours. One instruction applies to Sofwave in particular: radiofrequency (RF) treatments are generally avoided afterward, and your doctor decides whether to combine them and at what interval.
During treatment you may feel warmth or tingling. Topical numbing is applied under The Comfort Code when needed, and your doctor can adjust settings for comfort.
Both work through the body's own response, so change arrives gradually rather than on the day. After Ultherapy Prime, some may notice early changes, and a fuller effect may develop over about two to three months; how long it lasts varies by person.
After Sofwave, some may notice early changes, and further change may appear gradually over about three months; individual results vary.
The number of sessions is set by your doctor based on your skin and goals. For Sofwave, the manufacturer's clinical data support a single session; for either treatment, additional sessions may be recommended depending on how your skin responds.
Neither can be performed if you have a pacemaker, defibrillator, or another implanted electronic device, and neither is performed over open wounds or severe (cystic) acne. Ultherapy Prime is also not performed over a metal implant in the treatment area.
Before either treatment, tell us if you are pregnant or breastfeeding, have a history of severe allergies or a neuromuscular disease, or have taken isotretinoin (an oral acne medication) within the past six months. Your doctor decides whether the treatment can go ahead.
Yes. Either may be planned alongside skin boosters or other booster treatments as part of a broader design, since each addresses a different layer or concern. Neither is performed over an area where filler has been injected. Your doctor determines the sequence and the interval.
What follows a lifting treatment is a design question of its own, which we look at in our piece on what comes after lifting. If radiofrequency is also on your list, Ulthera vs Thermage sets out how ultrasound and radiofrequency differ, and our map of lifting energies places all of them by layer.
On a short trip, same-day treatment is possible for many procedures, subject to your Personal Consultant Session and the Doctor's Treatment Design. Flight timing depends on the type of treatment and how your recovery is going. Tell us your departure date before you book, and your doctor will set the treatment order and the interval before your flight.
The right choice depends on your skin thickness, the pattern of laxity, and the results you are looking for — there is no single answer that fits everyone. In the Personal Consultant Session, we map your concerns, goals, and travel schedule first. In the Doctor's Treatment Design, your doctor sets the energy lines, depth, and intensity for Ultherapy Prime, or the energy levels and passes for Sofwave.
Sometimes the plan is one of them on its own; sometimes it sits alongside other options. The useful question is not which device is stronger. It is which layer your concern sits in, and which energy reaches it.
