Definition: The term "pheomelanin" refers to a pigment found in the skin of plants, including apples and citrus fruits. It is also known as melanin, as it is produced by cells located on the surface of plants. In humans, pheomelanin can have beneficial effects, such as improving skin appearance. However, excessive amounts of this pigment in the skin can cause skin conditions like photodermatosis (sunburn) and black斑点症 (black spots). This condition is caused by a lack of melanin or other pigments that protect the skin from sun damage. Pheomelanin is also associated with certain types of cancer, particularly melanoma. It has been found to be present in human breast milk, suggesting that pheomelanin might affect breast cancer risk. However, more research is needed to fully understand its effects and the potential for cancer-related mutations. In summary, while pheomelanin does have benefits such as improving skin appearance, excessive levels can cause some negative side effects like skin conditions. Further study is necessary in this area to better understand its role and health effects.
