welcome PowerPoint Presentation free download Biology Diagrams 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.
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
Skin Pigment Disorders Biology Diagrams
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 Skin pigmentation refers to the color of your skin. It's determined by the amount and type of melanin, a pigment made by specialized skin cells known as melanocytes. Changes in melanin production can cause pigment disorders, such as hyperpigmentation (dark spots), hypopigmentation (light spots), depigmentation (white spots or patches).
Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis. Differences in skin pigmentation result both from the relative ratio of eumelanin (brown-black) to pheomelanin (yellow-red), as well as the number of melanosomes within melanocytes. Pheomelanin accounts for the 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.

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
Melanin: What Is It, Types & Benefits 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.
