Blue-Violet Light Irradiation Dose Dependently Decreases Carotenoids in Human Skin, Which Indicates the Generation of Free Radicals

Figure 2

The kinetic course of the cutaneous carotenoids degradation after the irradiation with blue light at doses of 50 J/cm² (mean + SD, solid line) and 100 J/cm² (mean − SD, dotted line) and the subsequent restoration. shows the significant degradation in comparison to the initial level before irradiation ().
