A retrospective study by Yalici-Armagan and Elcin in Dermatologic Therapy in 2020 is a useful reality check. Twenty-four people were reviewed a median of 4.3 months after one session of microfocused ultrasound on the lower face. In that study, blinded raters comparing photographs saw improvement in 20.9% and no change in 62.5%, while 45.9% of the subjects themselves reported improvement.

The gap was statistically significant, and the authors suggested that photographs may miss what people feel: firmer skin when touched, a crisper edge when turning the head. For you, the practical lesson is to set two kinds of goals, how the area looks and how it feels, and to judge both at around three months rather than in the first weeks.

That study did not use the Prime unit specifically, and it was small. It still shows that a lower-face lift with ultrasound is a subtle tool, not a dramatic one.

The same study scored three lower-face signs: an irregular jawline, the marionette area beside the mouth and laxity under the chin. A Prime plan for this region usually maps them separately. The 4.5 mm transducer works on the SMAS along the jaw, the 3.0 mm row is often used under the chin where the tissue is thinner, and 1.5 mm passes address surface looseness.

The on-screen image lets the operator check tissue thickness before each line, which matters near the jaw where bone sits close below. Ask the doctor to show you which of the three signs the plan addresses and how many lines go to each one.

• Soft jawline with early jowls: deep rows along the jaw.
• Mild looseness under the chin: mid-depth rows, sometimes combined with deep ones.
• Deep marionette folds: ultrasound may soften the edge, but volume loss needs another approach.

Lines on the neck and the upper chest respond less to ultrasound alone than a jawline does. Casabona and Nogueira Teixeira, in a 2017 retrospective study in the Journal of Cosmetic Dermatology, treated 47 people with visualized ultrasound followed in the same session by calcium hydroxylapatite (Radiesse) diluted one to one with lidocaine and injected under the skin. Blinded scores for neck lines moved from moderate-to-severe toward mild at 90 days.

The combination adds an injectable with its own care points, so it deserves a separate conversation rather than an add-on at the counter.

People with heavy skin excess, deep folds or marked neck bands usually see less than they hope, and a candid doctor will raise surgery or other options. Very thin faces with little fat can also look less full after heat, so the plan may skip some areas.

Treatment is postponed during pregnancy, over broken or irritated skin, or near implants in the zone. Bring a list of past fillers, threads and earlier lifting sessions, because these change how the doctor reads the scan.
