What is the common name for the condition known as vitiligo?

The condition known as vitiligo is characterized by the loss of skin pigment, which leads to white patches appearing on the skin. This occurs due to the destruction or malfunctioning of melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color. Therefore, the common name for vitiligo can be accurately described as skin depigmentation, as it highlights the primary feature of the condition – the absence of pigment in certain areas of the skin.

The other options do not accurately capture the core aspect of vitiligo. While skin dryness refers to a different condition involving the lack of moisture, skin aging pertains to the general changes that occur in the skin over time, including wrinkles and loss of elasticity. Skin pigmentation, on the other hand, is a broader term that can encompass various aspects of skin color, including both increased and decreased pigmentation but does not specifically refer to the condition of vitiligo. Thus, the choice of skin depigmentation is the most precise in describing vitiligo and its effects on the skin.
