In brief: Reacts with light
The bilirubin in the patient's body absorbs energy in the blue range of the spectrum (420-470 nm lights are blue).
As a result of absorbing this energy the bilirubin molecule is broken down and then metabolized and excreted in the urine or feces. Over time the bilirubin level will return to normal.

In brief: Excrete pigment into
The yellow pigment responsible for the jaundice in newborns is called indirect bilirubin which has high affinity to fat and is not water soluble.
The bilirubins deposited under skin change its chemical nature when exposed to special light, i.e., water soluble, and get excreted through urine.
