Advances in Microneedle-Based Approaches for Skin Diseases: A Comprehensive Review of Therapeutic Applications and Future Perspectives

Background: Psoriasis is a persistent skin condition for which only symptom management is currently available. Topical and systemic medicines, physical therapy, and other methods are all part of the standard treatment strategy. New medication delivery methods for psoriasis are urgently needed because of the present methods' shortcomings. Objective: The objective of this article is to provide a comprehensive description of microneedles as well as their development in the treatment of psoriasis and the clinical challenges associated with them. Discussion: The microneedle (MNs) technology is better than other transdermal delivery methods because it has so many benefits, including low invasiveness, painlessness, simplicity, and enhanced patient compliance. Coated microneedles, hollow microneedles, dissolving microneedles, and solid microneedles are the four basic categories into which researchers have so far sorted the fast-expanding area of microneedles. Each of these kinds of microneedles offers its own unique advantages due to their unique properties and layout. Conclusion: MNs may significantly improve transdermal medication penetration by mechanically opening skin micropores. Meanwhile, this method demonstrates distinct benefits over injection and oral delivery, such as painless application, the least amount of intrusion, the simplicity of self-administration, and avoiding the first-pass impact.
