Novel formulations for topical delivery of tranexamic acid: assessing the need of epidermal targeting for hyperpigmentation disorders

Targeting tranexamic acid in the epidermal layer makes more amount of drug available for action on melanocytes, the target site for tranexamic acid. Novel drug delivery formulations like liposomes, solid lipid nanoparticles, nano-lipidic carriers, and topical beads have the potential of achieving epidermal targeting. Epidermal targeting of tranexamic acid can help in the superior delivery of the drug, making its topical treatment more efficient.
