The level of 4-hydroxynonenal (4-HNE)-protein adducts in keratinocytes following UVA (30 J/cm²) or UVB (60 mJ/cm²) radiation and treated with cannabidiol (CBD, 4 μM) in a three-dimensional culture model. x: statistically significant differences vs. non-treated cells, p < 0.05; y: statistically significant differences vs. CBD-treated cells, p < 0.05; a: statistically significant differences vs. UVA-irradiated cells, p < 0.05; b: statistically significant differences vs. UVB-irradiated cells, p < 0.05.
