Phototherapy. Phototherapy is treatment with light. It is used in some cases of newborn jaundice to lower the bilirubin levels in your babyâs blood through a process called photo-oxidation. Oxidation is the process of adding oxygen to change a substance (in this case, the bilirubin).
When too much bilirubin builds up in a new babyâs body, the skin and whites of the eyes might look yellow. This yellow coloring is called jaundice. When severe jaundice goes untreated for too long, it can cause a condition called kernicterus.aundice is the yellow color seen in the skin of many newborns. Jaundice happens when a chemical called bilirubin builds up in the babyâs blood. During pregnancy, the motherâs liver removes bilirubin for the baby, but after birth the babyâs liver must remove the bilirubin.
