Vitiligo: Causes, Symptoms, Types and Treatment Options

Vitiligo is a long-term skin condition in which patches of skin lose their pigment and turn white. It affects roughly 1–2 % of people worldwide, appears in every skin type and usually starts between the ages of 10 and 30. It is not contagious, it is not dangerous and it can be managed – but the sooner you understand what is happening in your skin, the better your chances of stopping the spread and getting colour back.

This guide covers what vitiligo is, why it develops, how it is diagnosed and what actually works: from narrowband UVB phototherapy you can do at home to cosmetic camouflage.

What is vitiligo?

Skin colour comes from melanin, a pigment produced by cells called melanocytes. In vitiligo these cells stop working or disappear from certain areas of the skin, so no melanin is produced there and the skin turns milky white.

Vitiligo is classed as an autoimmune condition: the body's own immune system attacks its melanocytes. Around 30–40 % of people with vitiligo have a relative with the condition, and it often appears together with other autoimmune diseases, most commonly thyroid disorders.

What causes vitiligo?

The exact cause is still not fully understood. Three mechanisms are considered the main drivers, and in most people several of them act together:

1. Autoimmune attack. White blood cells (T-lymphocytes) mistake melanocytes for a threat and destroy them. They release a signalling molecule, interferon-gamma, which recruits even more immune cells to the area – a vicious circle that keeps the patch growing.
2. Oxidative stress. Melanocytes in vitiligo skin handle free radicals poorly. When the balance between free radicals and the body's antioxidants tips, the pigment cells damage themselves. This is why antioxidants (vitamins C and E, selenium, zinc, copper) are part of most vitiligo protocols.
3. Neurogenic factors. Chemical messengers released by nerve endings in the skin may be toxic to melanocytes, which would explain why some patches follow nerve pathways (segmental vitiligo).

Common triggers that start or accelerate vitiligo include severe stress, sunburn, skin injury (cuts, friction, burns – the so-called Koebner phenomenon), chemical exposure and hormonal changes. Genetics loads the gun; a trigger pulls it.

Vitiligo symptoms: how it starts

The first sign is usually a small white spot that slowly grows or multiplies. Typical first locations are:

• hands, fingers and wrists
• around the eyes and mouth
• elbows, knees, feet and ankles
• armpits and groin
• genitals

Patches are usually symmetrical (both hands, both knees). Hair growing from a patch may turn white too. The skin itself feels normal – there is no itching, pain or scaling. If a white area is scaly, itchy or raised, it is more likely something else (see below).

How is vitiligo diagnosed?

Not every white spot is vitiligo. Pityriasis versicolor (a fungal infection), post-inflammatory hypopigmentation after eczema or injury, and pityriasis alba in children can look similar. A dermatologist confirms vitiligo with a Wood's lamp – a UV light under which vitiligo patches glow bright blue-white. In unclear cases a small skin biopsy is taken.

Because vitiligo often travels with other autoimmune conditions, ask your doctor for these blood tests at diagnosis:

• TSH (thyroid function) – thyroid disease is found in up to 30 % of people with vitiligo
• antinuclear antibodies (ANA)
• full blood count – to rule out pernicious anaemia
• fasting glucose or HbA1c – to rule out diabetes
• vitamin D and vitamin B12 – both are frequently low in vitiligo

Treating an undiagnosed thyroid problem or a vitamin deficiency often makes vitiligo itself easier to control.

Types of vitiligo

You may also read about trichrome vitiligo – a patch with a white centre, a lighter ring and normal skin around it, which simply shows a patch in the process of spreading.

Is vitiligo dangerous?

Vitiligo is primarily a cosmetic condition, but it has practical consequences:

• Sunburn. White patches have no melanin and burn within minutes. Use SPF 50+ on every exposed patch, every day.
• Eye and ear changes. Melanocytes also live in the retina and inner ear; mild changes are common but vision and hearing are rarely affected.
• Other autoimmune diseases. Thyroid disease, type 1 diabetes, pernicious anaemia, alopecia areata, Addison's disease, rheumatoid arthritis and coeliac disease are all more frequent in people with vitiligo.
• Emotional impact. Anxiety, low self-esteem and social withdrawal are common, especially when the face or hands are affected. This is a real medical issue, not vanity – and it is one more reason to treat rather than "just live with it".

Vitiligo treatment: what actually works

Twenty years ago patients were told vitiligo could not be treated. That is no longer true. The goal of treatment is repigmentation – bringing melanocytes back into the white patches – and stopping new patches from forming. Results depend on how long the patch has existed (fresh patches respond best), where it is (face and trunk respond better than hands and feet), your age and how consistently you follow the protocol.

1. Narrowband UVB phototherapy (311 nm)

Phototherapy is the most effective and best-studied vitiligo treatment. Narrowband UVB light at 311 nm calms the immune attack in the skin and stimulates the melanocytes that survive in hair follicles to migrate back into the patch. It works for adults and children, on the face, body and scalp.

You can have phototherapy in a clinic 2–3 times a week, or do it at home with a handheld narrowband UVB lamp such as the Dermalight 80R or the Philips BU-1S. Sessions take seconds to a few minutes per patch; first signs of repigmentation (small brown dots inside the patch) typically appear after 6–12 weeks, and a full course lasts 4–14 months.

2. Topical treatments

• Topical corticosteroids – prescription creams for small, new patches; effective but not for long-term use on the face.
• Calcineurin inhibitors (tacrolimus, pimecrolimus) – prescription creams that calm the immune reaction without thinning the skin; often combined with UVB.
• JAK inhibitors (ruxolitinib cream) – the newest prescription option, approved for non-segmental vitiligo in the EU and USA. It blocks the interferon-gamma signal described above.
• Skin-care products for vitiligo such as Vitistop gel with superoxide dismutase, babchi (Psoralea) oil, copper and zinc, designed to be applied before UVB or sun exposure to support the repigmentation process. Cosmetic products do not replace medical treatment, but many of our customers use them as part of a daily routine alongside phototherapy – see their results.

3. Nutritional support

Oxidative stress is part of the disease, so a diet and supplements rich in antioxidants are a sensible foundation. Vitamin D, vitamin B12, folic acid, zinc, copper and selenium are the nutrients most often found low in vitiligo. Vitistop tablets combine the antioxidant extract EXTRAMEL® with vitamins C, E, B9 and B12 and the minerals zinc, copper and selenium, which contribute to the protection of cells from oxidative stress and to normal skin pigmentation (copper).

4. Surgical options

For stable vitiligo (no new patches for at least a year) that has not responded to other treatment, a dermatologist can transplant your own melanocytes into the patch: punch grafting, suction-blister grafting or cell-suspension transplantation. Risks include scarring, a cobblestone texture and uneven colour. Surgery is rarely needed if phototherapy is started early.

5. Cosmetic camouflage

While you wait for repigmentation – or if treatment is not for you – waterproof concealers made specifically for vitiligo hide patches for 24–48 hours and survive water and sweat. See our guide to vitiligo makeup and cover-up products and the camouflage category.

6. Depigmentation and tattooing

If more than 50–80 % of the skin has lost colour, some people choose to remove the remaining pigment with a prescription cream (monobenzone) for an even skin tone. It is permanent and leaves the whole skin very sun-sensitive. Medical tattooing (micropigmentation) can work on lips and small stable patches, but the colour fades and never tans with the surrounding skin.

Lifestyle: the part of treatment you control

• Protect patches from the sun – SPF 50+ daily; sunburn creates new patches.
• Avoid skin trauma – tight straps, friction, harsh scrubs and cuts can trigger patches at the injury site.
• Manage stress – many people can date the start of their vitiligo to a stressful period. Sleep, exercise and relaxation are part of the protocol, not an optional extra. More in Vitiligo and stress.
• Eat for your skin – colourful vegetables, fruit, nuts, fish, and enough protein; limit alcohol and processed food.
• Be patient and consistent – repigmentation is measured in months, and skipped sessions are the most common reason treatment fails.

Frequently asked questions about vitiligo

Can vitiligo be cured?
There is no cure yet, but vitiligo can be stopped and patches can be repigmented, sometimes completely. Segmental vitiligo and fresh patches on the face and trunk have the best outlook.

Does vitiligo spread?
Non-segmental vitiligo usually progresses in phases, with quiet periods and flare-ups. Early treatment with UVB phototherapy is the most reliable way to stop the spread.

Is vitiligo hereditary?
Partly. About one in three people with vitiligo has an affected relative, but the risk of passing it directly to a child is only around 5–7 %. Genes create the tendency; triggers such as stress or sunburn decide whether it appears.

Is vitiligo contagious?
No. You cannot catch vitiligo from anyone, and you cannot pass it on by touch, blood or shared items.

Can vitiligo go away on its own?
Spontaneous repigmentation happens in roughly 10 % of cases, usually in small, new patches. Waiting is a gamble; treating early is not.

Which doctor treats vitiligo?
A dermatologist. Ask specifically about narrowband UVB phototherapy and the blood tests listed above.
