White patches on the skin, especially on the face, hands or body, often raise curiosity and concern.
Many people wonder if this condition is dangerous or contagious.
The truth is, this condition is a skin health issue called vitiligo, a pigmentation disorder that causes the skin to lose its natural colour and turn lighter or white.
Vitiligo is an autoimmune disease that happens when the body’s immune system attacks melanocytes, the cells that are responsible for producing skin colour.
It is estimated that about 0.5% to 1% of the world’s population lives with this condition.
The white patches usually appear symmetrically, such as on both hands or both feet, but they can also occur in other areas like the hair, inside the nose or in the mouth.
Although vitiligo does not cause physical pain, it can have a significant emotional impact, especially on people with darker skin.
The condition can affect anyone, regardless of gender, race or age.
