The skin is prone to mechanical injuries and damage and the skin collagen changes with age. Herbs and aloe vera gel are used experimentally and traditionally in the skin repair and rejuvenation. In this study, the effect of gelatin-aloe vera nanofibers on the expression of collagen I gene after skin microneedling was investigated in male mice under standard laboratory conditions. Skin microneedling was performed on the backs of the tested mice. Groups were subjected to treatments with saline, aloe vera gel, and gelatin-aloe vera nanofibers for 48 h. The expression of collagen I gene was evaluated through sampling and purification of tissue RNA by Real time PCR method. According to the results, skin injury resulted in a significant reduction in the expression of the collagen I gene in the treatment groups compared to the control group. In comparison, treatment with aloe vera gel and aloe vera/gelatin nanofibers significantly increased gene expression compared to the model group. Furthermore, the existing Glucomannan increased gene expression at the site of injury by passing through pores.
