Are there side effects of the treatment?

While very effective for treating Crigler-Najjar syndrome, exposing your skin to fluorescent light or sunlight can increase your risk of being exposed to ultraviolet radiation that can lead to skin cancer. The new technology that uses LED blue lights (similar to the light that emits from your phone screen) reduces your exposure to ultraviolet radiation and is the safest treatment option.

As you age and grow, phototherapy might become ineffective to treat Crigler-Najjar syndrome because your body mass increases, which causes your skin to thicken. This makes it more difficult for light to reach bilirubin molecules.
