Vitiligo is an acquired skin disorder characterized by white spots. It is the total absence of pigment-producing cells in the skin called melanocytes.
Who Gets Vitiligo?
Vitiligo appears to affect at least 1% to 2% of the population, irrespective of sex, race, or age. The more dark skinned a person is, the more their vitiligo stands out, because of the contrast between affected and unaffected areas of skin. Hence, there is a higher prevalence of vitiligo in countries with darker-skinned populations.
In half of all vitiligo cases, onset occurs between the ages of 10 and 30. There are a few reported cases of vitiligo present at birth. Vitiligo in old age also rarely happens.
Both genetic and environmental factors contribute to vitiligo. Many patients attribute the onset of their vitiligo to physical trauma, illness, or emotional stress. Often mentioned is the emergence following the death of a relative or after severe bodily injury. Even sunburn reaction may precipitate vitiligo. buy benoquin otc
