Dandelion Extracts Protect Human Skin Fibroblasts from UVB Damage and Cellular Senescence
Dandelion leaf and flower extracts inhibit UVB irradiation-induced ROS production. UVB irradiation caused significant increases in the fluorescent intensity of H2-DCFDA, reflecting the higher level of ROS; however, dandelion leaf and flower extracts (300 μg/mL) significantly decreased UVB irradiation-induced ROS generation when added both before and after UVB irradiation.
