Vitiligo is a disorder in which white patches develop on the skin. The patches may appear on any part of the body, including the hair, eyes, and mouth.
The white patches are due to the destruction of melanocytes cells. These cells in the skin make pigment. Loss of pigment causes the skin to become lighter. It looks especially lighter compared to normal skin nearby. This is why vitiligo is more visible in darker-skinned people.
The exact cause of the pigment loss is not known. Possible causes include:
It is likely that a genetic defect makes the cells more vulnerable to damage.
Vitiligo is more common in people between the ages of 10 and 30 years. Other factors that may increase your chance for vitiligo include:
The main symptom is white patches on the skin. These patches may be clumped together or all over the body. Some common sites of pigment loss include:
White or prematurely graying hair and hair loss may also occur.
Vitiligo often begins with a rapid loss of skin color. This is followed by a long period without any change. Cycles of pigment loss and stability may occur again later. The cycle can continue throughout life.
The doctor will ask about your symptoms and medical history. A physical exam and eye exam will be done. The diagnosis is usually made by the appearance of the skin. A skin biopsy may be done to confirm. Special UV lamps may be used during the skin exam. Blood tests are often taken to look for signs of autoimmune diseases.
There is no known cure for vitiligo. Often, the longer the patches exist, the harder it is to repigment the area. Treatment is geared to decreasing the appearance of patches by:
This may be done by:
PUVA used to be the most common type of repigmentation. Now it is being largely replaced by narrow band UVB (nbUVB). You apply a psoralen cream or take psoralen medication orally. You then expose yourself to UV light A (UV-A) from the sun or an artificial source. The medicine is activated by UV-A. It may repigment white patches. This treatment takes months and can cause sunburn-type reactions. It may also cause nausea and an increased risk of skin cancer .
This is a special UV laser. It is shown to be effective in localized cases.

This involves removing the remaining pigment from your normal skin. This treatment makes your whole body the same white color. It is only done if you have already lost a large amount of your normal skin color and repigmentation has not been successful. The medicine used is called monobenzyl ether of hydroquinone 20%. This treatment takes about one year to complete. It can cause side effects, such as redness and swelling of your skin.
You can make your white patches less noticeable. Makeup, dyes, stains, or self-tanning lotions can work as a cover. However, the color from dyes, stains, and lotions slowly wears off.
The purpose of sunscreen is to:
Depigmented areas are at much higher risk for skin cancer.
For some, vitiligo can cause social distress, affecting quality of life. Cognitive-behavioral therapy can be used to:
There is no known way to prevent vitiligo.
It is important to protect the depigmented areas from too much sun exposure. You can do so by wearing protective clothing and applying sunscreen.
Some other medical conditions occur more often in persons with vitiligo. Your doctor will likely ask about symptoms that might indicate a vitiligo-related disorder.
