Coenzyme Q₁₀ (CoQ₁₀) restored ultraviolet B radiation- (UVB-) induced damage in the epidermis of the skin. (a) Hematoxylin and eosin (H&E) staining of the epidermis and dermis on the mouse skin. The picture was captured at 10x magnification using an electron microscope. (b) The thickness of the dermis was measured in response to CoQ₁₀ treatment. CON: control group without exposing to UVB; MOD: model group with ointment base exposed to UVB; CoQ₁₀: treatment with CoQ₁₀ sunscreen exposed to UVB; TiO₂: positive control with titanium dioxide (TiO₂) sunscreen exposed to UVB. n ≥ 3. Results were shown as the mean ± SD. ^∗p < 0.05 vs. MOD.
