Hey, phototherapy is done only in neonatal jaundice... as when bilirubin is exposed to light it undergoes photoisomerization to form “photobilirubin." The photobilirubin is formed photochemically from bilirubin near the surface of the skin and is then transported in plasma to the liver, where it is excreted in bile. The formation of photobilirubin appears to be a highly efficient process in which the photobilirubin is continuously removed from the skin by the plasma and is then excreted. read more in -
