Condition

Vitiligo

Vitiligo is a condition where the immune system destroys the cells that give skin its color, leaving smooth white patches. It is not painful, not contagious and not caused by anything you did, and treatment can bring color back to many patches if it is given long enough.

Start here

Almost everyone with new white patches has decided it was something they did wrong. It was not — vitiligo is autoimmune, the body's own immune cells removing the pigment cells in the skin. It is treatable, and it is slow: color comes back a few specks at a time, the face and neck answer best, and hands, feet and lips are stubborn. Vitiligo does not make you unwell, but being looked at all day is tiring, and if it is affecting your mood or your day that is a real reason to treat it.

Key Facts

How commonAround 1 in 100 people worldwide. It affects every skin tone equally, though the contrast makes it far more noticeable on deeper skin tones
Who gets itAny age, and men and women about equally. Roughly half of cases start before age 20
Curable or managedManaged - color can be brought back to many patches, but treatment is long and patches can return after it stops
Prescription neededUsually. The treatments that actually restore pigment are prescription creams and in-office light therapy
Time to improveMonths, not weeks. The face often shows the first change around three to six months

What It Is

Skin color comes from melanocytes, cells at the base of the outer layer of skin that make the pigment melanin. In vitiligo the immune system destroys them, so the skin left behind has no pigment and turns milk white.

A vitiligo patch is flat, smooth and sharply edged, and the skin inside feels exactly like the skin around it — no scale, no thickening, no lump. Most other pale patches change the texture too. Patches are usually not itchy or sore, though some people notice mild itching just before a new one appears.

It shows up most often around the eyes and mouth, on the hands and fingers, on the elbows, knees, ankles and feet, and where skin gets rubbed or pressed. Hair inside a patch can turn white, and when it does the patch is harder to repigment, because the pigment cells that refill it are stored in the hair openings.

There are two main variants. Non-segmental vitiligo is the common one — patches on both sides of the body in a roughly matching pattern, moving in waves over years. Segmental vitiligo affects one area on one side, often starts in childhood, spreads for a while and then usually stops for good. Losing pigment over most of the body is called universal vitiligo.

Symptoms

Matching areas of color loss

Symmetrical Patches

Milky-white patches appearing in a mirror-image pattern on both sides of the body, often around the eyes and mouth, on the hands, elbows, knees and feet. Edges are usually sharply defined. It is the most common pattern.
One area only

Segmental

Patches confined to one part of the body, often on one side of the face or one limb, usually appearing in childhood or young adulthood. It tends to spread for a while and then stop. It behaves differently from the symmetrical form and is treated differently.
Large areas of skin

Widespread

Loss of color over large areas, sometimes with white hairs in the patches. Skin without pigment burns very easily and needs careful sun protection. Support matters here as much as treatment, because the visible impact can be significant.

How It Looks by Skin Tone

Two pale patches with sharp edges sit against lightly tanned skin, and the difference between the patch and the skin around it is subtle.The area around the mouth and chin on medium olive skin. A white patch with a sharp, scalloped border sits above the upper lip and runs onto the chin, with no scale or roughness inside it.The backs of the fingers and knuckles of one hand on brown skin. Sharp-edged milk white patches cover the knuckles and the sides of two fingers, standing out strongly against the surrounding brown skin.A white vitiligo patch on the forearm of deep brown skin, with dozens of small dark brown dots appearing inside it around the hair openings and a rim of returning color at the edge.

Vitiligo occurs at the same rate in every skin tone, but living with it is not the same. On deeper skin tones the contrast is far greater, so the same pigment loss is visible from across a room. Studies consistently find a heavier psychological and social burden, and that is a legitimate reason to treat rather than watch.

On lighter skin tones patches can go unnoticed for a long time, often first spotted in summer as a place that does not tan. A dermatologist may use a Wood's lamp, a hand-held ultraviolet light, to make faint patches show up. Two points matter on deeper skin tones. Returning color arrives as small dark dots around the hair openings, so a treated patch goes through a speckled stage lasting months — it looks worse than a plain white patch to some people, and it is progress. And camouflage products and self-tanners containing dihydroxyacetone can be matched to deeper tones, but pharmacy shade ranges are built for lighter skin, so ask for deeper shades. Skin inside a patch has no melanin at all, whatever the tone around it, so it burns quickly. Daily sunscreen on exposed patches is part of the treatment, not an extra.

Where It Shows Up

Around the eyes and the mouth
The skin around the eyes and around the mouth is the commonest place on the face, and in the usual type the patches appear on both sides in a roughly matching pattern. Hair growing through a patch can turn white too.

Hands, elbows, knees and feet
The hands and fingers are usually the first place noticed, then the elbows, knees, ankles and feet. These are the bony, exposed parts that get knocked most, and skin injury is one of the things that can start a new patch.

Where skin is rubbed or pressed
It also turns up where skin is rubbed or pressed — a belt line, a bra strap, a watch band. That pattern has a name, and it is one of the reasons a new patch can appear somewhere that seems random.

What Happens in the Skin

This is what is going wrong under the skin, in the order it happens. Click a step to see it.

How Vitiligo happens
Skin basics
BARRIEREPIDERMISDERMISPIGMENT CELLMELANOCYTES0NORMAL SKIN1PIGMENT CELLS UNDER STRESS2SOMETHING TIPS THEM OVER3THE IMMUNE SYSTEM ATTACKS4THE ATTACK SETS UP CAMP

Pigment cells sit along the base of the top layer of skin and make melanin, the color in skin and hair. Making it leaves chemical waste behind, and a healthy pigment cell clears that waste as fast as it builds up. The immune system reads these cells as part of the body and leaves them alone.

In people prone to vitiligo the pigment cells are more fragile than usual. Normal chemical waste builds up inside them instead of being cleared, so the cells are already under strain before anything happens to the skin.

A sunburn, a cut, constant rubbing or certain chemicals push the stressed cells past their limit. They give off signals that the immune system reads as damage, which is why a new patch so often appears exactly where the skin was injured.

Immune cells called T cells arrive, treat the pigment cells as a target and destroy them. Where they are gone there is no melanin left, so the skin turns milk white. This is the step almost every vitiligo treatment is aimed at.

Long-lived memory immune cells stay parked in that patch and remove any new pigment cell that appears. This is the state the whole list below is pushing on: it is why a treated patch can turn white again once treatment stops, and why maintenance twice a week matters.

The outer film of dead cells and oil. It holds water in and keeps irritants out, and it is thinner than a sheet of paper. Almost every dry, itchy, stinging skin problem starts here.

The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.

The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.

Vitiligo develops in four steps, and each is a place treatment can be aimed.

The pigment cells come under stress. In people prone to vitiligo, melanocytes are fragile, and normal chemical stress inside the cell builds up instead of clearing.

Something tips them over. A sunburn, a cut, constant friction or certain chemicals push them past their limit, and they release signals the immune system reads as damage.

The immune system attacks. Immune cells called T cells recognize the pigment cells as a target and destroy them. Most treatments block this step.

The attack sets up camp. Long-lived memory immune cells stay parked in the patch and remove any new pigment cells. That is why a treated patch can lose color again once treatment stops, and why maintenance matters.

Underneath all four is genetics. Dozens of genes have been linked to vitiligo, most involved in how the immune system tells your own cells from foreign ones. They set the risk; the steps above turn it into a patch.

Risk Factors

Most of what makes one person likelier to develop vitiligo is inherited immune tendency. You did not cause it, and apart from protecting your skin from injury there is little to change.

Inherited
Family history
Vitiligo runs in families, but not in a simple pattern. Many people have a relative with it or another autoimmune condition, and many do not.
Other health conditions
Other autoimmune conditions
Thyroid disease is the most common companion. Type 1 diabetes, pernicious anemia and alopecia areata also appear more often.
Other health conditions
Halo moles
A mole with a white ring comes from the same immune attack, and in some people it shows up before vitiligo does.
Other health conditions
Some cancer treatments
Immunotherapy drugs called checkpoint inhibitors can cause vitiligo-like pigment loss. Never stop one on your own — ask your doctor.
Age
Age
It can start at any age, but most cases begin before age 30.
Skin injury & exposure
Skin injury
Cuts, burns, surgical scars, tattoos and constant friction can bring a patch out at that spot. This is the Koebner response, and it is avoidable.
Skin injury & exposure
Severe sunburn
Both an injury and a chemical stress to pigment cells, which is why it is a common trigger for a first patch.
Skin injury & exposure
Certain chemical exposures
Some phenol and catechol compounds in adhesives, rubber products and hair dyes destroy pigment cells in susceptible people.

Course

Vitiligo is unpredictable, which is one of the hardest things about it. Non-segmental vitiligo, the common type, moves in waves — an active spell, a long still period, then another. Segmental vitiligo spreads within one area on one side over roughly six months to two years, then stops for good.

Active spreadWeeks to months
Pigment is being lost right now

Look for blurred rather than sharp edges, tiny confetti-like white spots, and new patches where skin was recently injured. Treatment does the most good now, so be seen rather than wait and see.

Still phaseCan last several years
It holds completely still

A person may hold still for years before the next active spell. A minority repigment on their own, usually not completely, and nobody can predict who.

Face and other sun-exposed skin
During treatmentResults vary by site
Where the patch is decides how well it works

Face, neck and trunk do best. Elbows, knees, hands, fingers, feet and lips do worst, and patches where the hair has turned white often do not refill at all, because the reservoir of pigment cells in the hair openings is gone.

FaceNeckTrunk
After color returnsLong term
Relapse after stopping treatment is common

A treatment cream twice a week on a repigmented area substantially reduces the chance the patch returns. Vitiligo does not shorten life or damage organs, so long-term decisions are about how visible it is and how much it bothers you.

What Makes It Better & Worse

Vitiligo happens in four steps — stress inside the pigment cell, a trigger that tips it over, the immune attack, and the immune memory that keeps color out. Step two is where most spread happens, and the one you can do something about.

What helps

  • Daily sunscreen on exposed patches Prevents triggering burns and limits the contrast.

What makes it worse

  • Sunburn An injury and a chemical stress at once, and depigmented skin burns faster.
  • Certain chemicals Some phenol and catechol compounds destroy pigment cells directly, including in some lightening creams.
  • Physical or emotional stress It does not cause vitiligo, but it can make an existing tendency act up.

What makes it worse

  • Injuring the skin Cuts, burns, tight straps, surgery and tattoos bring out new patches at that exact spot.
  • Constant friction and pressure Belt lines, bra straps, watch bands, rubbing shoes.

What helps

  • Topical steroid creams The usual first treatment for a few patches, in courses with breaks.
  • Topical calcineurin inhibitors Tacrolimus and pimecrolimus calm the same attack without thinning skin.
  • Ruxolitinib cream A prescription JAK inhibitor cream approved to restore pigment, used for months.
  • Narrowband UVB light therapy The mainstay for widespread vitiligo, two or three sessions a week.
  • Combining light therapy with a cream Repigments more skin than either alone.
  • Surgical pigment grafting For segmental or long-stable vitiligo, not while it is spreading.
  • Checking the thyroid Thyroid disease is common alongside vitiligo and often silent.

What helps

  • Maintenance twice a week Lowers the chance a repigmented patch turns white again.
  • Camouflage and self-tanner Changes nothing underneath, but makes daily life easier meanwhile.

What makes it worse

  • Stopping treatment when color returns Without maintenance, many repigmented patches lose color again.
  • Waiting to be seen Patches white for years respond much less well than fresh ones.

Over-the-Counter Products

Everything here you can buy without seeing anyone.

Daily broad-spectrum sunscreen
Daily broad-spectrum sunscreen
Always
Skin inside a patch has no melanin, so it burns fast, and a burn can bring out new patches. Sunscreen on exposed patches every day prevents that and keeps the skin around the patch from tanning, which lowers the contrast. Use it whatever your skin tone. It restores no color on its own.
Camouflage makeup and self-tanner
Camouflage makeup and self-tanner
Moderate evidence
Cover creams made for skin conditions, and self-tanning lotions containing dihydroxyacetone, color the surface of a white patch for a few days at a time. They change nothing underneath and they do not interfere with treatment. For many people they make daily life easier during the year or more that repigmentation takes.
Antioxidant supplements
Antioxidant supplements
Weak evidence
Ginkgo biloba and polypodium leucotomos extract are the two most often asked about. Small studies suggest they may slow spread a little or add slightly to light therapy, but the trials are small and the results are inconsistent. They are not a treatment on their own, and no supplement has been shown to bring color back.

Prescriptions

These need a prescription.

Strong evidence
A JAK inhibitor cream approved specifically to restore pigment in vitiligo, applied twice a day. In trials about a third of people had most of the color back on the face by six months, and results keep improving past a year. It is slow, it is expensive, and color can be lost again if it is stopped, so it is usually continued about twice a week afterwards.
16:9 hero for Tacrolimus (Protopic). Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Tacrolimus (Protopic) works in the skin
Strong evidence
The usual choice for vitiligo on the face, eyelids, neck and skin folds, because it quiets the immune attack without thinning the skin, so it can be used in those places for months. It stings or feels warm for the first week or two in some people. It works best on the face and much less well on hands and feet.

Clobetasol Propionate
Strong evidence
A strong steroid cream, the standard first treatment for a small number of patches on the body. It is used in courses with breaks, often a few weeks on and a few weeks off, because continuous use thins the skin and leaves stretch marks. It is not used on the face or eyelids, where tacrolimus is chosen instead.

Moderate evidence
A gentler relative of tacrolimus, used on the same delicate areas and often preferred for children or for people who find tacrolimus too stinging. It works the same way on the immune attack. It is generally a little less effective than tacrolimus for vitiligo.
A white cream tube on a white background, with a plain white label reading Monobenzone and a blue swoosh beneath it.
"Bleaching" cream
Moderate evidence
Monobenzone cream removes the pigment that is left, so the skin ends up one even color. It is only considered when vitiligo already covers most of the body and repigmenting is not realistic. The change is permanent and cannot be reversed, and the skin afterwards has no protection from the sun at all, so it is a decision taken slowly and never as a first step.

Limited evidence
A vitamin D cream sometimes added to a steroid or to light therapy, on the idea that it helps pigment cells return. On its own it does very little for vitiligo. Its value is as a partner treatment, and the evidence for even that is mixed.

Prednisone in short pulses
Moderate evidence
Low-dose steroid tablets taken on two days a week for a few months are used for one purpose in vitiligo: to stop pigment loss that is spreading quickly. It is a brake, not a way to bring color back, so it is paired with a cream or light therapy. Blood sugar, blood pressure and mood are watched while it is running.

Limited evidence
Tablets in the same family as ruxolitinib cream. Trials show real repigmentation, particularly when they are combined with light therapy, and they are the most active area of vitiligo research right now. They are not yet standard treatment for vitiligo, and they carry more risk than a cream, so they are used through a specialist or a trial.

Procedures

These are done in the office, usually over several visits.

Strong evidence
Narrowband UVB, two or three sessions a week in a cabinet at the clinic, is the mainstay for vitiligo that covers more than a few small patches. It calms the immune attack and coaxes pigment cells out of the hair openings. Expect three to six months before the face shows change and a year or more for a full course, and better results when it is combined with a cream.
16:9 hero for Excimer Laser. Never cropped: the tone strip and the corner logo depend on the full frame.Diagram: how Excimer Laser works in the skin
Strong evidence
The same wavelength as narrowband UVB delivered through a handpiece, so it treats one patch and leaves the skin around it alone. It suits a small number of patches, especially on the face, and it is the practical option for children who cannot stand still in a cabinet. Sessions are usually twice a week, and it is not used for widespread vitiligo.
Surgical pigment grafting
Moderate evidence
Pigment cells are taken from normal skin and moved into a white patch, either as tiny grafts or as a cell suspension. It is the best option for segmental vitiligo and for patches that have been completely stable for a year or more, including patches where the hair has gone white. It is never done while vitiligo is spreading, because the graft is attacked in turn.

When to See a Dermatologist

Go earlier than feels necessary — vitiligo is much easier to treat while it is new and spreading than after years of sitting still, and everything that restores pigment is prescription or done in the office. Book for a new white patch of any size, patches growing or new ones appearing, blurred edges or small confetti-like spots, hair inside a patch turning white, or new patches where clothing rubs. Go sooner for facial patches, which respond best and respond better treated early, and go too if stable vitiligo is affecting your mood, your work or how you live — a medical reason, not a cosmetic one. A Wood's lamp in a darkened room confirms it and shows faint patches invisible in normal light, and blood tests, thyroid function as standard, check for the conditions that travel with it rather than diagnose the skin.

Complications

Sunburn inside the patches

Skin inside a vitiligo patch has no melanin at all, so it burns quickly and can burn badly while the skin around it is fine. A burn is also an injury, and injuries can bring out new patches, so a bad burn can make things worse in two ways at once. Daily broad-spectrum sunscreen on exposed patches prevents it, and it counts as treatment rather than an extra.

Thyroid and other autoimmune disease

The same immune tendency that causes vitiligo makes other autoimmune conditions more likely, and thyroid disease is the common one. It is often silent for a long time, which is why a thyroid blood test is standard at the first visit and is sometimes repeated later. Type 1 diabetes, pernicious anemia and alopecia areata also appear more often than average.

The weight of being looked at

Vitiligo does not make you unwell, but it is visible, and being looked at all day is tiring. Anxiety, low mood and avoiding ordinary things are common, and they are worse where the contrast is greater or the patches are on the face and hands. This counts as a medical reason to treat, not a cosmetic one, and it is worth saying out loud at the appointment.

Lookalikes

Tinea Versicolor

A common yeast overgrowth that leaves pale patches on the chest, back and shoulders, so it is often taken for vitiligo. Its patches are pale rather than milk white, they have a fine dusty scale that shows if you scratch the surface, their edges are blurred, and they often run together into a map-like sheet. It also clears with an antifungal, which vitiligo does not.

Pityriasis alba

The pale, dry, fuzzy-edged patches children get on the cheeks and upper arms, usually alongside a dry or eczema-prone skin type. They are pale rather than white, the surface is slightly dry and fine-scaled instead of smooth, and the border fades gradually rather than stopping sharply. They fade on their own over months with moisturizer and sun protection.

Pale marks left by an old rash

Eczema, psoriasis, a burn or even a treated rash can leave pale skin behind where the inflammation was, and people often read that as vitiligo starting. The giveaway is the shape: these marks copy the outline of the rash that caused them, they are pale rather than completely white, and they slowly refill on their own over months. Vitiligo patches are milk white and do not fade back by themselves.

Myths

+
  • "Vitiligo is contagious." Not in any way — not by touch, a shared towel, a pool or anything else. It is an internal immune process, not an infection.
  • "It was caused by something I ate." No food or drink has ever been shown to cause vitiligo. The claim about milk after fish is folklore, and cutting foods out does not slow it down.
  • "Nothing can be done about it." This one does real harm — it keeps people at home during the years when treatment works best. Topical treatments, light therapy and newer prescription creams restore color for a substantial proportion of people, particularly on the face.
  • "Only people with deeper skin tones get vitiligo." It occurs at the same rate in every skin tone. Greater contrast makes it more visible, so it gets noticed more often.
  • "Sun exposure will even out the color." It does the opposite. A patch has no pigment cells, so it cannot tan — the skin around it does, widening the contrast, and the patch burns.
  • "Vitiligo means I will eventually turn completely white." Most people do not. Losing pigment over almost the whole body is uncommon, and nothing about a first patch predicts it.
  • "Vitiligo turns into skin cancer." It does not, and research has not found higher skin cancer rates in people with vitiligo, including those on light therapy. Depigmented skin still burns easily, so sun protection is worth doing anyway.

Questions Patients Ask

+

Will my color ever come back?

Often, at least partly. Face, neck and trunk repigment well for a substantial proportion of people. Hands, fingers, feet and lips do poorly, and patches where the hair has gone white usually do not refill, because the pigment cells that restock a patch live in the hair openings. Nobody can promise a result, which is why photographs at the start are worth taking.

How long does treatment take?

Longer than almost anyone expects. The first visible change on the face usually takes about three to six months, and a full course often runs a year or more. Judging a treatment at week six is judging it before it has done anything.

Is vitiligo dangerous?

Not to your body. It does not shorten life, damage organs or turn into anything else. Two points matter: depigmented skin burns easily, and autoimmune conditions such as thyroid disease are more common alongside it, which is why blood tests are usually done.

Will it spread over my whole body?

Most likely not. Vitiligo moves in waves, and losing pigment over almost the entire body is uncommon. Nothing predicts the course from the first patch, which is why active spread is treated promptly.

Can my children get it?

Higher than average, but still low. Vitiligo runs in families through a group of immune genes rather than one, so most children of a parent with vitiligo never develop it.

Does stress cause vitiligo?

No — the underlying immune tendency is genetic. But major stress, illness or surgery frequently lines up with the start of an active spell. Managing stress is worth doing for its own sake, and it is not a substitute for treatment.
