Lipid-based nanocarriers, including liposomes, ethosomes, and solid lipid nanoparticles (SLNs), have revolutionized topical and transdermal drug delivery by enhancing skin permeation and bioavailability. This review explores the design, mechanisms, and clinical applications of these systems, focusing on their ability to encapsulate both hydrophilic and lipophilic drugs. Advances in surface modification and stimuli-responsive strategies are also discussed, highlighting their potential for personalized dermatotherapy.
