Sequential Monopolar-bipolar Versus Monopolar Radiofrequency: A Cross-sectional Survey on Patient Satisfaction

Background: Radiofrequency (RF) technologies are widely used for non-invasive facial rejuvenation. While monopolar RF (M-RF) provides deeper tissue heating, monopolar-bipolar RF (MB-RF) platforms aim to target multiple dermal depths to improve both contouring and surface texture. Real-world patient satisfaction data on MB-RF remain limited. Methods: A descriptive cross-sectional survey was conducted at cosmetic dermatology facilities in Ho Chi Minh City (March-July 2025). Adults (≥18 years) undergoing MB-RF with the DENSITY NOIR device were enrolled. Participants rated improvements in firmness/contouring, pore appearance, skin tone and wrinkles at one-week and one-month post-treatment. Overall satisfaction, comfort and willingness to repeat the treatment were recorded. A planned subgroup analysis was performed for participants with prior M-RF experience. Results: Of 130 participants, 31 (23.9%) had previously undergone M-RF. MB-RF achieved 63.1–64.6% satisfaction for firmness/contouring with texture-related satisfaction ranged from 60.8%–62.3%. Overall satisfaction was 69.2%, with low discomfort (2.3%). Subgroup analysis showed no significant efficacy differences between MB-RF and prior M-RF, but MB-RF was significantly more comfortable and preferred for reuse. Conclusion: MB-RF (DENSITY NOIR) provides high patient satisfaction with strong tolerability and comparable efficacy to prior M-RF, positioning it as a patient-preferred non-invasive rejuvenation option.
