Monopolar Radiofrequency for Dermal Prejuvenation: Scientific Rationale and Mechanisms of Action

This is the authors' abstract. We don't add key points for this paper.

OBJECTIVES: To summarize the scientific rationale for the use of the monopolar radiofrequency tissue tightening system (monoRF) for the prevention of dermal aging (termed prejuvenation). MATERIALS AND METHODS: This narrative review summarizes the basic science of dermal aging and monoRF-induced collagen remodeling and neocollagenesis. Studies supporting the mechanism of action of monoRF treatment and its use for prejuvenation are reviewed. RESULTS: Dermal aging is largely attributed to the accumulation of fragmented collagen and depleted collagen levels. Collagen remodeling and neocollagenesis may be induced by monoRF treatment, resulting in immediate tissue tightening and subsequent collagen production, respectively. Preliminary data and expert opinion suggest that early and repeated intervention with monoRF may prevent progressive skin laxity via synergistic and cumulative effects. CONCLUSIONS: MonoRF treatment shows potential as a prejuvenation strategy, with preliminary evidence supporting that it induces collagen remodeling and neocollagenesis. Future research should focus on long-term, prospective studies to determine the preventive benefits of consistent annual treatment for aging.
