White skin on the face is an obvious sign of a skin problem. This happens
mainly because of loss of pigmentation in the skin. Special skin cells called
melanocytes produce a dark brown pigment called melanin. This pigment gives a
specific skin color to every individual.
There are several causes that can lead to formation of whitish patches on
face. Some of the common causes are mentioned as follows.
Leucoderma: This is also referred to as vitiligo disease. Here, the size of
the patches grows with the passage of time. The causes for this condition are
not clearly known to us. In many cases, it has been found to be an autoimmune
disorder. In some people, it is hereditary and the disease runs in their family.
It can affect people of any age group but are more common in women than in
men.
Pityriasis Alba: This is a chronic skin disorder that mostly affects small
children. The size of the white patch is usually 1 or 2 cm in diameter, but in
some children, it can be as big as 20 cm. The patches usually appear in the
winters and the skin tends to become dry and scaly. Its real cause has not yet
been found, but it can be triggered by stress, heat, smoke, etc.
Idiopathic Guttate Hypomelanosis: This is a genetic disorder and is often
associated with aging. It is more common in women above the age of 40. In this
condition, the skin becomes thin and the number of melanocytes decrease. As a
result, no melanin is produced at all. It gives white spots on face that are
small in size and are flat and round in shape. These spots are more visible
after prolonged exposure to the sun, when the facial skin turns dark except for
those patches.
