Neonatal hyperbilirubinemia — jaundice caused by a buildup of bilirubin — is a common condition seen in premature and term infants. Exposure to light allows the body to break down the product and excrete it through the urine.
The accumulation in the skin can also be treated with the exposure of lights. The optimal wavelength of light is in the visible blue spectrum. The optimal wavelength range is 470 to 510 nm. Since these wavelengths are in the visible spectrum, there’s no risk of carcinogenesis and no reason to expect an increased incidence of cancer formation in infants who have been treated by the bilirubin lights.
