            <jats:p>A prospective, single-center, blinded, split-body, randomized clinical study investigated HIUS and MFU-V for improvement of upper arm skin laxity and crepiness. Subjects received a single treatment to the upper arms.</jats:p>

            <jats:title>RESULTS</jats:title>
            <jats:p>Fourteen female subjects completed the study. Assessments compared Day 30 and Day 90 follow-up visits with baseline. HIUS was as effective as MFU-V in improving arm laxity and crepiness. Investigators and subjects rated improved arm laxity/crepiness at Day 90. Most subjects were satisfied with the improvement of arm laxity/crepiness. There was no statistically significant difference in pain scores observed between the HIUS and MFU-V. The MFU-V treatment took more time to perform than the HIUS treatment.</jats:p>

Radiofrequency (RF) therapy is a popular noninvasive skin-tightening method, yet objective evaluations of its effectiveness remain limited.
This study assesses RF therapy's impact on facial skin laxity and oiliness using a 3D skin analyzer, multi-parameter skin analysis, and histological analysis.
Thirty-two patients (skin types III-V) underwent full-face monopolar RF treatment, with follow-ups over 24 weeks. Clinical photographs, 3D imaging, and specialized probes measured elasticity and sebum levels. Skin biopsies were taken before and 2 months post-treatment. Improvement was assessed through patient questionnaires and dermatologist evaluations.
Significant improvements in jawline sagging and nasolabial folds were observed in 2D/3D images. Quantitative analysis confirmed RF-induced skin rejuvenation, with a statistically significant increase in skin radiance at 4 and 8 weeks. Sebum production decreased notably at 8 and 24 weeks, as confirmed by the sebum index. Elasticity improved, with increased viscoelasticity and reduced retraction time. Histological analysis revealed reduced dermal inflammation, decreased sebaceous gland volume, and enhanced collagen and elastic fiber density. At 2 months, 53.1% of patients reported over 50% improvement. No severe adverse events occurred.
Monopolar RF effectively enhances skin laxity by remodeling collagen and reorganizing elastic fibers. Histological findings and skin analyzer data support RF as a reliable, noninvasive treatment for improving skin firmness and reducing oiliness.
