Manuka oil suppresses UV-B-induced increase in epidermal thickness. (a) Representative photographs of haematoxylin and eosin stained dorsal skin sections taken at the end of the experiment from the no UV-B irradiation control (no UV-B) group, vehicle only group (vehicle), and the group that received 10% manuka oil (manuka oil), respectively. Magnification: 200x fold; scale bar: 200 μm. (b) The relative values of epidermal thickness are estimated from the digital photoimages of haematoxylin and eosin stained sections and depicted as mean ± SEM (n = 6 per group). ^##: significantly different from no UV-B control group (P < 0.01). **: significantly different from vehicle only group (P < 0.01).
