Chitosan in Dermatology

Benefiting from its intrinsic properties, chitosan resembles extracellular matrix (ECM), and, hence, various forms of chitosan have been practiced in dermatology. Nanofibers of chitosan have been successfully utilized in wound dressing for regeneration of various types of wounds. Chitosan nanoparticles have also been used in cell reprogramming, e.g. induced pluripotent stem cell, which is known as a new method for alopecia treatment, as signaled in drug delivery. Chitosan hydrogels are 3D macromolecular networks providing niche-like milieu that can enhance cellular activity. Thus, design and implementation of chitosan-based hydrogels enhances dermatological conditions. This mini-review highlights the importance and applications of chitosan-based structure as a harbinger for new emerging materials for dermatology uses.
