Skin (caution signal: tumor proliferation)

harms (preclinical) Low preclinical study (mouse) (A)

In a mouse model, red LED light at 642 nm increased the size of skin tumors, epidermal thickness, and proinflammatory cytokines. A caution signal for light therapy on the skin, but it is PRECLINICAL (mouse): it does not demonstrate risk in humans.
