Obesity has become a major public health threat, as it can cause various complications such as diabetes, cardiovascular disease, sleep apnea, cancer, and osteoarthritis. The primary anti-obesity therapies include dietary control, physical exercise, surgical interventions, and drug therapy; however, these treatments often have poor therapeutic efficacy, significant side effects, and unavoidable weight rebound. As a revolutionized transdermal drug delivery system, microneedles (MNs) have been increasingly used to deliver anti-obesity therapeutics to subcutaneous adipose tissue or targeted absorption sites, significantly enhancing anti-obese effects. Nevertheless, there is still a lack of a review to comprehensively summarize the latest progress of MN-mediated treatment of obesity. This review provides an overview of the application of MN technology in obesity, focusing on the delivery of various therapeutics to promote the browning of white adipose tissue (WAT), suppress adipogenesis, and improve metabolic function. In addition, this review presents detailed examples of the integration of MN technology with iontophoresis (INT) or photothermal therapy (PTT) to promote drug penetration into deeper dermis and exert synergistic anti-obese effects. Furthermore, the challenges and prospects of MN technology used for obesity treatment are also discussed, which helps to guide the design and optimization of MNs. Overall, this review provides insight into the development and clinical translation of MN technology for the treatment of obesity.
