Hypertrophic scar (HS) tends to raised above skin level with high inflammatory microenvironment and excessive proliferation of myofibroblasts. The HS therapy remains challenging due to dense scar tissue which makes it hard to penetrate, and the side effects resulting from intralesional corticosteroid injection which is the mainstay treatment in clinic. Herein, bilayer microneedle patches combined with dexamethasone and colchicine (DC-MNs) with differential dual-release pattern is designed. Two drugs loaded in commercially available materials HA and PLGA, respectively. Specifically, after administration, outer layer rapidly releases the anti-inflammatory drug dexamethasone, which inhibits macrophage polarization to pro-inflammatory phenotype in scar tissue. Subsequently, inner layer degrades sustainedly, releasing antimicrotubular agent colchicine, which suppresses the overproliferation of myofibroblasts with extremely narrow therapeutic window, and inhibits the overexpression of collagen, as well as promotes the regular arrangement of collagen. Only applied once, DC-MNs directly delivered drugs to the scar tissue. Compared to traditional treatment regimen, DC-MNs significantly suppressed HS at lower dosage and frequency by differential dual-release design. Therefore, this study put forward the idea of integrated DC-MNs accompany the development of HS, providing a non-invasive, self-applicable, more efficient and secure strategy for treatment of HS.
