Bottom Line
This narrative review examines redox-active microneedles, an emerging technology that combines redox biology with microneedle drug delivery systems. While the concept shows promise for treating various conditions including wound infections, cancer, and inflammatory diseases, this appears to be a descriptive rather than systematic review. The technology is described as being in early development with growing patent activity and clinical trials. However, without systematic methodology, quality assessment, or quantitative synthesis, the review provides limited high-quality evidence for clinical decision-making. Clinicians should view this as an interesting technological development requiring further rigorous evaluation before clinical implementation. The broad therapeutic claims require validation through well-designed clinical trials before any practice recommendations can be made.

Abstract
Reactive oxygen and nitrogen species are essential to several biological functions, from maintaining cellular homeostasis to driving disease progression and aging. As such, the precise modulation of cellular redox states has emerged as a promising medical strategy. In parallel, microneedle technology has rapidly advanced over the past two decades, offering minimally invasive, targeted, and painless delivery of therapeutics. This review presents a comprehensive analysis of the emerging field of redox-active microneedles (RAMs), a novel class of wearable medical devices with broad potential for treating infected wounds, cancer, psoriasis, diabetes, arthritis, hair loss, skin aging, and potentially many other conditions. By integrating redox biology with advanced microneedle-based drug delivery systems, RAMs are poised to transform personalized and precision medicine, an evolution supported by a growing number of patents, clinical trials, and rapid advancements in catalytic, photodynamic, and nanomedicine research.
