# Real‐World Evaluation of Sequential Monopolar‐Bipolar RF Device for Rejuvenation

## TL;DR

This study evaluates a skin rejuvenation device and finds it effective with high patient satisfaction and minimal side effects.

## Contribution

Provides real-world clinical data on a sequential RF device for facial aesthetics.

## Key findings

- Most patients showed moderate to marked improvement in skin appearance.
- High patient satisfaction and strong likelihood to recommend the treatment.
- Minimal downtime and no adverse events were reported.

## Abstract

Sequential monopolar‐bipolar radiofrequency (RF) systems aim to provide multi‐layer dermal heating for skin tightening and rejuvenation. Real‐world outcome data for these devices remain limited.

To evaluate the clinical efficacy, safety, and patient‐reported outcomes of the DENSITY NOIR sequential RF device for aesthetic facial indications.

A retrospective multicentre case series was conducted across dermatology clinics in the United States. Consecutive patients who underwent DENSITY NOIR RF treatment and had standardized pre‐and post‐treatment photographs, along with follow‐up surveys completed ≥ 30 days after treatment, were included in the study. Provider‐rated improvement (4‐point scale) and patient‐reported outcomes, including visible improvement, satisfaction, pain, downtime, and likelihood to recommend, were summarized descriptively. Age‐stratified subgroup analyses and correlation assessments were also performed.

Twenty‐five patients (88% female; age range 26–55 years) met the inclusion criteria. All demonstrated improvement from baseline; 56% showed moderate improvement, while 24% showed marked improvement. Patient satisfaction was high (100%), with 48% “very satisfied.” Likelihood‐to‐recommend scores were strong (median 10/10). Downtime was minimal; 92% reported none. Age‐subgroup analyses showed greater proportions of marked improvement and “very satisfied” responses among patients > 55 years. Pain scores were low, and no adverse events were recorded.

Sequential RF treatment demonstrated meaningful aesthetic improvement with excellent tolerability, high satisfaction, and negligible downtime. Findings support its value as a minimally invasive skin‐rejuvenation option.
