Vitiligo is a chronic autoimmune condition in which the skin loses its pigment-producing cells (melanocytes), resulting in white patches that can appear anywhere on the body.
Vitiligo affects approximately 0.5–2% of the global population regardless of ethnic background. It occurs when melanocytes — the cells responsible for producing skin pigment — are destroyed by the immune system.
The condition can develop at any age but most commonly appears before age 30. It may be more noticeable in people with darker skin tones. Vitiligo is not contagious and is not medically dangerous, though it can have significant psychological and social impact.
The course is unpredictable — patches may remain stable, slowly expand, or occasionally repigment spontaneously. Treatment aims to restore colour or even out skin tone.
People with Vitiligo often experience the following symptoms.
Well-defined white or milky patches of skin, often symmetrical, that may appear on the face, hands, arms, feet, and around body openings.
Early loss of colour in the hair on the scalp, eyebrows, eyelashes, or beard, sometimes occurring before age 35.
Loss of normal colour on the mucous membranes inside the mouth and nose.
New patches may appear at sites of skin injury, friction, or trauma, a process known as the Koebner response.
Certain factors may increase your likelihood of developing Vitiligo.
Common approaches to managing vitiligo. Always consult a healthcare provider for personalized treatment.
Prescription steroid creams may help restore some pigment, especially when started early on small patches.
Narrowband UVB light therapy, administered two to three times per week, can stimulate melanocyte regrowth in affected areas.
Tacrolimus or pimecrolimus creams may be used on sensitive areas like the face and neck where steroids are less suitable.
Ruxolitinib cream is a newer FDA-approved treatment that can help repigment affected skin by modulating the immune response.
Diagnosis is primarily clinical, based on the appearance of characteristic white patches. A Wood's lamp examination can help visualise patches. Blood tests may be ordered to check for associated autoimmune conditions such as thyroid disease.
See a dermatologist if you notice new or expanding areas of skin losing colour, especially if it affects your self-esteem or if you have a family history of autoimmune disorders.
Steps that may help reduce the risk of developing or worsening vitiligo.
No proven prevention exists
Sun protection helps prevent sunburn on depigmented skin
Early treatment may slow progression
Stress management may help reduce flares
If left untreated or poorly managed, vitiligo may lead to:
No, vitiligo is not contagious in any way. It is an autoimmune condition where the body's own immune system attacks pigment-producing cells.
Some treatments can help restore pigment to affected areas, especially with early intervention. Results vary, and not all patients achieve full repigmentation.
Vitiligo may gradually spread over time, though the rate varies. Some people have stable patches for years while others experience more rapid progression.
