Taking blue light will not darken your baby’s skin, it is possible for the skin to turn lime green, but this can be reversed.
1. Usually blue light is used for the treatment of jaundice in newborns. The principle of blue light treatment is to convert unconjugated bilirubin, which is then excreted through urine or excreted through bile to the intestines and then excreted through the intestines.
2. Blue light has no obvious effect on melanocytes and will not stimulate melanocytes to secrete more melanin and cause skin darkening.
For some babies with high bilirubin, the skin may turn greenish after taking blue light, which is not pigmentation and can be reversed, and the color can return to normal after stopping taking light.
It is recommended to consult a medical professional if necessary.
