The antioxidant enzyme activities were altered by Coenzyme Q₁₀ (CoQ₁₀) sunscreen treatment in ultraviolet B radiation- (UVB-) treated skin. The activities of (a) malondialdehyde (MDA), (b) superoxide dismutase (SOD), and (c) glutathione peroxidase (GSH-Px) in the UVB-treated skin tissue in response to CoQ₁₀ sunscreen 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 for each group. Results were shown as the mean ± SD. ^∗p < 0.05 vs. MOD.
