PHOTOPROTECTION IN ERYTHROPOIETIC PROTOPHYRIA: MECHANISM OF PHOTOPROTECTION BY BETA CAROTENE
Journal of Investigative Dermatology, 1977 Erythropoietic protoporphyria is a genetic disease caused by the accumulation of protoporphyrin IX. This molecule absorbs 400-nm light and its presence is at times associated with severe cutaneous photosensitivity. The only effective treatment for this disease is oral administration of beta carotene.
