2016 Pearson Education Inc Biology Diagrams Melanin is responsible for the pigmentation of the skin and hair. It also protects the skin from the sun. Albinism is a genetic condition that causes people to have very little or no melanin The actual skin color of different humans is affected by many substances, although the single most important substance is the pigment melanin. Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin color of darker-skin humans.
Pigment disorder Characteristics Treatment Albinism. This is a rare, inherited disorder. It reduces the amount of melanin pigment in the skin, hair, and eyes. People with albinism (albinos) have white hair, pale skin, and pink or blue eyes. Their eyes may seem red in different lighting conditions.
Melanin: Types & Related Disorders Biology Diagrams
Melanin is a natural substance that determines the color of hair, skin, and eyes in people and animals. Special cells called melanocytes make melanin. Special cells called melanocytes make melanin. Melanin is a pigment responsible for skin tone. Melatonin is a hormone that regulates your waking and sleeping cycle. Does melanin cause vitamin D deficiency? Some experts believe that people who have darker skin are more prone to vitamin D deficiency than people with lighter skin. This is because excess melanin absorbs the UV rays responsible
Pigmentation disorders can cause hyperpigmentation (increased skin color) and hypopigmentation (reduced skin color). These changes can be localized (in certain areas) or generalized (all over). Conditions affected by melanin include: Albinism: This inherited disorder reduces melanin pigment in skin, hair, and eyes.It causes white hair, pale skin, and pink or blue eyes.

Skin pigmentation, which refers to how much melanin the body generates, determines the color of the skin. The two main types of melanin, eumelanin, and pheomelanin, are produced by
