Vitiligo is a long-term condition in which patches of skin lose their colour. It affects an estimated 0.5% to 2% of people worldwide, across all ethnic groups, but it is often more visible, and more stigmatised, on darker skin. In some communities, people with vitiligo face myths that it is contagious, a curse or caused by diet.
This guide explains what causes vitiligo, the different types, treatment options including newer therapies, how to protect the skin, and the emotional side of living with a visible skin condition.
Imagine a 14-year-old girl who notices a pale patch around her eye. Within a year, patches appear on her hands and knees. Classmates stop sitting near her because someone said it is catching. She starts wearing long sleeves in the heat and stops going to parties. A nurse at the clinic explains what vitiligo is, offers treatment options, and puts her in touch with a support group. The patches do not disappear overnight. But the shame begins to.
What is vitiligo?
Vitiligo happens when melanocytes, the cells that produce pigment (melanin), stop working or are destroyed. In most people, this is thought to be an autoimmune process, in which the immune system attacks the melanocytes. Genetics play a role, and vitiligo is more common in people with other autoimmune conditions such as thyroid disease, type 1 diabetes or alopecia areata.
Myths and facts
| Myth | Fact |
|---|---|
| Vitiligo is contagious | It cannot spread from person to person |
| It is caused by eating fish with milk | Diet does not cause vitiligo |
| It is a curse or punishment | It is a medical condition |
| It is a form of leprosy | It is completely different from leprosy |
| It always spreads all over the body | Its course varies; many people have stable patches |
Types of vitiligo
- Non-segmental (generalised) vitiligo: the most common type; patches on both sides of the body, often symmetrical, commonly on hands, face, around body openings, joints and areas of friction.
- Segmental vitiligo: patches on one side or one area of the body, often starting in childhood, usually stabilising after a period.
- Other forms: focal (a few patches) and universal (most of the body).
Diagnosis
A healthcare provider usually diagnoses vitiligo by examining the skin, sometimes using a Wood’s lamp (ultraviolet light). Blood tests may check for thyroid disease or other autoimmune conditions.
Treatment options
| Treatment | Notes |
|---|---|
| Topical corticosteroids | Often first-line for small areas; used for limited periods under supervision |
| Topical calcineurin inhibitors (tacrolimus, pimecrolimus) | Useful for face and thin skin |
| Topical JAK inhibitor (ruxolitinib cream) | A newer treatment approved in some countries for non-segmental vitiligo |
| Narrowband UVB phototherapy | For widespread or active vitiligo; several sessions per week for months |
| Oral treatments for rapidly spreading disease | Specialist use only |
| Surgical grafting | For stable, segmental vitiligo in selected people |
| Camouflage | Cosmetic cover creams matched to skin tone |
| Depigmentation | For very extensive vitiligo, removing remaining pigment; a major decision with specialists |
Response varies. Face and neck often respond best; hands and feet respond less. Treatment works better when started early and usually takes months.
Sun protection
Skin without pigment burns easily. Use broad-spectrum sunscreen, protective clothing and shade. Avoid tanning, which increases contrast and risks burns.
Avoid unsafe “cures”
Be cautious about herbal mixtures, bleaching creams and unproven remedies sold with promises of cure. Some contain steroids, mercury or irritants that damage the skin; see our guide to skin bleaching dangers.
The emotional side
Vitiligo is not physically painful, but its emotional impact can be significant: anxiety, low self-esteem, depression, bullying and discrimination, particularly in cultures where it is misunderstood. Support helps:
- patient support groups and online communities;
- counselling or talking therapies;
- school education to prevent bullying;
- role models: models, athletes and public figures with vitiligo have increased visibility.
World Vitiligo Day is marked on 25 June each year to raise awareness.
Frequently asked questions
Is vitiligo contagious?
No. It cannot be passed from person to person.
Can vitiligo be cured?
There is no permanent cure, but treatments can restore colour in many people, especially on the face.
Does diet cause vitiligo?
No. Food does not cause vitiligo.
Who gets vitiligo?
People of any age and ethnic background; it often starts before age 30.
But should everyone with vitiligo seek treatment?
Not necessarily. Some people choose treatment; others embrace their skin as it is. Both choices are valid. What matters is accurate information, sun protection and freedom from stigma.
Your next step: If you or your child has new pale patches, see a nurse or healthcare provider for diagnosis, and ask about early treatment options. If someone you know has vitiligo, share the facts in this article to challenge myths.
