Which conditions are examples of hypopigmentation?

Hypopigmentation refers to a condition where there is a decrease in the normal pigmentation of the skin, resulting in lighter patches or areas. Vitiligo and albinism are classic examples of hypopigmentation.

Vitiligo is a skin condition characterized by the loss of pigment in certain areas, leading to white patches on the skin. This occurs due to the destruction of melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color.

Albinism is a genetic condition that results in little to no production of melanin in the skin, hair, and eyes. Individuals with albinism typically have very fair skin and hair, along with increased sensitivity to sunlight and risk for skin cancers.

Both conditions showcase the trait of reduced pigmentation in contrast to the surrounding skin, making them clear examples of hypopigmentation. Other options, while related to skin issues, represent either normal pigmentation variations or conditions where pigmentation is not significantly reduced.
