Mitochondrial damage and cytoskeleton reorganization in human dermal fibroblasts exposed to artificial visible light similar to screen-emitted light

Human skin is the tissue most responsive to sunlight, which may impair its integrity and regeneration. Although the visible spectrum (400–700 nm) constitutes roughly 44% of sunlight [1], it was considered to have minimal impact on the skin because of its low energy. In recent decades, the visible part of the sunlight spectrum therefore received a little attention concerning its possible contribution to skin damage. However, observations of immediate skin pigmentation following exposure to visible light [2] sparked increased interest.
