Color Disorders

Skin color is determined by the "melanin" pigment produced by skin cells. Sometimes problems may occur with the pigments that give skin color, and an area of ​​the skin produces too much melanin, darkening its color. Conversely, when no melanin is produced in a part of the skin, the skin becomes white. This is called skin pigmentation disorder.

Hyperpigmentation is a term used to describe areas of uneven pigmentation on the skin.

Hyperpigmentation on the skin is caused by an increase in melanin, which is responsible for color (pigment) in the body. Some conditions, such as pregnancy or Addison's disease (decreased function of the adrenal gland), can cause more melanin production and hyperpigmentation. Exposure to sunlight is a major cause of hyperpigmentation and makes hyperpigmented areas darker.
