Microfocused ultrasound,
does it really help with Improvement in the appearance of facial laxity and wrinkles?
research showsFacial HIFU or MFU is rated C because it has a small short-term improvement signal. Zhu 2024 used a randomized split-face design in 20 participants and analyzed all 20; blinded photography judged 14 of 20 improved at three months and facial-volume change was positive. The study did not specify one prespecified primary endpoint, however, and the between-side wrinkle result was null. A meta-analysis included 13 studies and 477 participants, but most were uncontrolled and used subjective GAIS ratings, supporting C with 45 points.
ads claimMarketing expands subtle photographic change into surgical lifting, certain wrinkle removal, and durable collagen regeneration. Evidence best fits modest short-term appearance change in mild-to-moderate laxity.
Useful facts when choosing a product
- Focused ultrasound creates thermal-coagulation points at selected tissue depths to induce contraction and remodeling.
- Improvement usually develops gradually, varies widely, and cannot be assumed equivalent to a surgical facelift.
- Procedure pain, erythema, edema, altered sensation, fat atrophy, burns, and rare nerve injury have been reported.

What the research actually shows
Zhu 2024 was a 20-person split-face untreated-control study of microfocused ultrasound, and Ling and Zhao 2023 was a systematic review and meta-analysis of MFU; neither was a radiofrequency study. Zhu did not specify one prespecified primary endpoint. At three months, lower-face volume on the control side was +0.49 mL according to the main text and table, while the abstract reported +0.42 mL, an internal numerical inconsistency in the original article. The six-month between-side volume difference and between-side wrinkle, pore, and pigment differences were null. Ling and Zhao pooled 13 studies and 477 participants, but most were single-arm. Absence of a sham control, no single prespecified primary endpoint, and some null six-month findings support C. For comparison, verdict 1755, which is C with 42 points, addresses monopolar radiofrequency, a different energy device.
Why this is classified as C (45)
Short-term appearance and volume signals in all 20 split-face participants are acknowledged, but no single specified primary endpoint, null six-month and wrinkle comparisons, subjective assessment, and uncontrolled literature concentration give C with 45 points.
Counterpoint. People with mild laxity who do not want surgery may see a small improvement, but expectations should remain conservative.
Rejudgment record. Cross-check applied — The 20-person MFU trial lacked a sham control and one prespecified primary endpoint, had some null six-month findings, and reported inconsistent control-side volume values in the abstract versus the main text and table, invoking rule ①-ⓒ
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Improved facial-laxity appearance at three months | C | Blinded photography and volume were positive in 20 participants, but the trial was small. |
| Improvement in facial wrinkles | D | Wrinkle change in the pivotal trial was not significant versus the control side. |
| Persistence of lifting for at least six months | C | Some subjective signal persisted, but the pivotal three-dimensional volume comparison was null at six months. |

|---|---|---|---|---|---|---|
| Zhu J et al. 2024 | Prospective randomized MFU split-face untreated-control trial | 20 participants with randomized facial sides; actual analysis 20 | Public and institutional grants from Chinese national, hospital, and Shandong provincial sources; no manufacturer funding reported | No single primary endpoint specified; multiple outcomes including blinded photographic GAIS, three-dimensional volume, and wrinkles | Control-side volume was +0.49 mL in the main text and table but +0.42 mL in the abstract; six-month volume and wrinkle differences were null. | Pivotal small exploratory randomized trial |
| Ling J and Zhao H. 2023 | Systematic review and meta-analysis | 13 studies and 477 participants | Academic university research; no external commercial funding reported | GAIS response and satisfaction at 90 and 180 days | Ninety-day response rate 0.77 (0.58 to 0.96); most evidence was single-arm. | Low-certainty synthesis |
