Background: Nanostructured lipid carriers (NLCs) are emerging as advanced drug delivery sys-tems with enhanced stability, controlled release, & improved bioavailability. These systems address limita-tions of traditional treatments, which often only alleviate symptoms and have side effects. Objective: The objective of this review is to explore advancements in NLC-based drug delivery, emphasizing their application in specific therapeutic areas, such as dermatology and cancer. It critically examines the po-tential of NLCs in overcoming the limitations of conventional treatments and compares them with solid lipid nanoparticles (SLNs). Key challenges are also discussed, including scale-up, regulatory considerations, and quality-by-design (QbD) approaches. Results: NLCs offer prolonged drug release, improved skin penetration, and enhanced bioavailability. Com-pared to conventional formulations, they also reduce adverse reactions and staining. Conclusion: NLCs, with their amphiphilic nature, represent a promising approach to topical drug delivery. They offer improved therapeutic outcomes & reduced side effects, and their potential in treating various dis-eases is promising.
