(A) Dorsal skins were photographed at 0, 7, 14, 17, and 21 days. After treatment, dorsal skins were collected and subjected to H&E staining. Representative micro-images of (B) skin sections, (C) skin thickness and (D) hair follicle bulb diameters. Data show the mean±SD (n=4). *P<0.05 values are considered significantly different.
