This one is a clean test because each patient served as their own control. Published September 22, 2025 in the Journal of Cosmetic Dermatology, it was a prospective, randomized, evaluator-blinded, split-face trial in 26 patients (25 women, mean age 43.2, Fitzpatrick III to IV). One side of the face got microfocused ultrasound (MFU) plus microneedle fractional radiofrequency (MFR) in a single session. The other side got MFU alone. Outcomes were read by VISIA, ultrasound, GAIS, and WSRS at baseline, 1 month, and 3 months.

At 3 months the combined side won on every VISIA metric: wrinkles down 40% versus 20% (p=0.02), pores 21% versus 4% (p=0.033), red areas 11% versus 4% (p=0.01), with texture 27% versus 15% by the 1-month mark (p=0.003). Ultrasound also caught real subcutaneous fat thinning on the combined side: masseter 5.15 to 4.40 mm and mid-cheek 6.92 to 5.58 mm (both p<0.001), more than MFU alone. Both physician and patient GAIS favored the combined side, and over 90% of patients were satisfied or very satisfied. Tolerability was reasonable, with pain VAS around 2.6 for MFU and 3.3 for MFR and only mild erythema, purpura, or edema clearing in 3 to 72 hours.

The takeaway: MFU coagulates the deep SMAS, MFR remodels across dermal depths, and stacking them in one visit treats different layers and outperforms MFU on its own. Stratify RF depth by zone (shallower fronto-temporal near 1.2 mm, deeper lower face up to 2.5 mm) and tell patients the real gains read out at 3 months.
