Abstract :
Microneedle Arrays (MNA( are innovative devices composed of tiny needles with dimensions ranging from tens of micrometers to a few millimeters. These microstructures, fabricated from various materials such as metals, polymers, ceramics, and biocompatible materials, have opened up a wide range of applications in various medical fields. By penetrating the upper layers of the skin or other tissues, MNAs offer novel methods for drug delivery, vaccination, sampling, and disease diagnosis. In this study, we will strive to gain a more detailed understanding of microneedles and their applications in the fields of aesthetics, medicine, and other areas by utilizing the latest research and providing more in-depth information. Additionally, the limitations and challenges associated with this technology will be examined and analyzed to enable us to make better use of microneedles in the future and enhance their strengths. Furthermore, a more thorough examination and categorization of microneedle types and their effects on the skin and underlying tissues will be conducted due to their significance in the application of this technology. Finally, by combining the data and findings obtained, we will be able to develop strategies for improving and enhancing the use of microneedles and expanding their applications in this field.
