What Is Phototherapy?
Phototherapy is a medical treatment that uses light to treat certain conditions, particularly neonatal jaundice, skin disorders, and some types of depression. In newborns, phototherapy is commonly used to reduce high levels of bilirubin in the blood, which can cause jaundice. The baby is placed under special blue-spectrum lights that help break down bilirubin so it can be excreted from the body.
In dermatology, phototherapy is used to treat skin conditions like psoriasis, eczema, and vitiligo by exposing affected areas to controlled ultraviolet (UV) light. Different types of phototherapy include UVB therapy, PUVA therapy (psoralen plus UVA), and LED light therapy. This treatment works by slowing the excessive growth of skin cells, reducing inflammation, and improving skin appearance. Phototherapy is typically administered under medical supervision to ensure the right dosage and prevent side effects such as burns or premature aging of the skin.
