title: Photobiology. Basic science.
abstract: Photobiology is the study of the effects of nonionizing radiation on biologic systems. The biologic effect varies with the wavelength region of the radiation. The radiation is absorbed by molecules in skin such as DNA, protein or certain drugs. The molecules are changed chemically into products that initiate biochemical responses in the cells.
