This review describes recent research using zebrafish models in dermatology, including skin pigmentation disorders, barrier function, wound healing and regeneration, pharmacological discovery, genetic and inflammatory skin conditions, and melanoma. By examining the research, ethical, and logistical merits of zebrafish NAMs, this review emphasizes their contribution to fostering more humane and efficient research frameworks.
