Dandelion Extracts Protect Human Skin Fibroblasts from UVB Damage and Cellular Senescence

Figure 3

Dandelion leaf and flower extracts inhibit UVB irradiation-stimulated MMP activity. UVB irradiation strengthened the fluorescent intensity of DQ gelatin, reflecting higher MMP activity; however, dandelion leaf and flower extracts (300 μg/mL) significantly decreased MMP activity when added both before and after UVB irradiation. Scale bar: 20 μm. (b) was the statistical analysis from (a) by imageJ software. # versus control; * versus UVB only. . Scale bar: 20 μm.
