Microneedles (MNs), composed of multiple micron-scale needle-like structures attached to a base, offer minimally invasive approach for transdermal drug delivery by penetrating the stratum corneum and delivering therapeutic agents directly epidermis or dermis. Hydrogel microneedles (HMNs) stand out among various MN types due their excellent biocompatibility, high drug-loading capacity, tunable drug-release properties. This review systematically examines matrix materials fabrication methods HMN systems, highlighting advancements in natural synthetic polymers, explores applications treating conditions such as wound healing, hair loss, cardiovascular diseases, cancer. Furthermore, potential HMNs disease diagnostics is discussed. The identifies key challenges, including limited mechanical strength, efficiency, lack standardization, while proposing strategies overcome these issues. With integration intelligent design enhanced control over dosage safety, are poised revolutionize expand personalized medicine.
