👉 The term "pheomelanin" refers to a pigment found in human skin and hair, specifically in the melanin (blue) component. It is a bimetallic compound consisting of two different metals, copper and zinc, that are related to each other by their position on the periodic table. Pheomelanin plays several important roles in the body. First and foremost, it helps protect the skin from harmful UV rays and bacteria through its ability to block out certain wavelengths of light. Pheomelanin is also an antioxidant, which means it can help reduce damage caused by free radicals and other pollutants. In addition to protecting the skin, pheomelanin also plays a role in regulating blood sugar levels. Pheomelanin is found in the hair follicles, where it acts as a pigment that helps regulate blood flow and prevent the buildup of excess melanin. This can help maintain a healthy complexion by preventing excessive growth of black hair. However, excessive amounts of pheomelanin can lead to skin discoloration or greasy hair. It is recommended to limit exposure to UV rays during the day to keep your skin clear and healthy.
