Cytoprotective activity of S. raeseri subsp. raeseri essential oil against H₂O₂-induced DNA damage on human immortalized keratinocyte (HaCaT) cells. HaCaT cells were incubated with S. raeseri subsp. raeseri essential oil (0.05 mg/mL and 0.5 mg/mL) for 20 min and then 20 min with H₂O₂ both in presence and in absence of the oil. Comet assay was performed to assess the H₂O₂-induced DNA damage. The data presented are the mean ± SD of three independent experiments performed in triplicates. * p < 0.05, *** p < 0.001 vs. untreated.
