Vitiligo: Symptoms, Diagnosis, and Treatment

What is vitiligo?

Vitiligo is an acquired depigmentation disorder in which the skin develops in milky white or completely white patches as a result of the loss of melanocytes, the cells that give the skin its color.

It most commonly appears on the face, hands, fingers, elbows, knees, genital area, and various other areas of the body. Hair and body hair may also turn gray in some areas.

Vitiligo is not contagious and does not turn into cancer. However, when it affects visible areas, it can seriously impact quality of life and psychological well-being.

Briefly, what you need to know

Vitiligo is not a fungal infection or infection.

It is not contagious.

The immune system and genetic predisposition play important roles in the development of the disease.

Not every white spot is vitiligo.

The disease may remain stable in some people, while it may progress in others.

The treatment has two main goals: to halt the progression of the disease and to restore the pigment.

Areas like the face and neck generally respond better to treatment than the fingertips and toes.

Treatment often takes months; expecting quick results is unrealistic.

What causes vitiligo?

There is no single cause of vitiligo.

Currently, the disease is understood as an autoimmune process in which the immune system targets melanocytes in individuals with a genetic predisposition.

The interaction between oxidative stress, cellular stress mechanisms, and the immune system may also play a role in the development of the disease.

Because:

“"Vitiligo is caused by stress."”

That's too simple.

Stress can trigger disease activity in some individuals, but it is not the sole cause.

Is vitiligo contagious?

No.

Vitiligo:

by touch,

by using the same towel,

through sexual contact,

from the pool

It is not contagious.

This message is especially important for patients who experience social stigma because of their visible lesions.

Are all white spots vitiligo?

No.

There are other conditions that can resemble vitiligo:

pityriasis alba,

pityriasis versicolor,

postinflammatory hypopigmentation,

nevus depigmentosus,

some chemical leukodermas,

other rare pigment disorders.

Therefore, self-diagnosing with something like "I saw a white spot = vitiligo" is incorrect.

How is vitiligo diagnosed?

Diagnosis in most patients:

story,

appearance of lesions,

distribution,

dermatological examination

It is placed with.

If needed, Wood's lamp assessment can help to better visualize borders and depigmentation.

In atypical cases, dermoscopy or, rarely, biopsy may be necessary.

Current international recommendations particularly emphasize assessing not only the extent of the disease but also its activity and stability when making a diagnosis.

What are segmental and nonsegmental vitiligo?

This is one of the fundamental clinical distinctions.

Nonsegmental vitiligo: This is the most common form. It often presents bilaterally or with a symmetrical distribution.

Segmental vitiligo: Usually affects one side of the body, showing a more limited distribution along a specific segment, and its course can vary.

This distinction is important in treatment planning.

Is the disease active or stable?

This question is very important from a treatment perspective.

The appearance of new lesions, the expansion of existing areas, or certain clinical findings may suggest that the disease is active.

In stable disease, no new lesions or expansion may be observed for a certain period of time.

The treatment goal may be to control disease progression in active disease and, in stable disease, to particularly enhance repigmentation.

How is vitiligo treated?

There is no single treatment.

Treatment plan:

Disease type + active/stable status + extent + affected area + age + impact on quality of life

This is done by evaluating them together. The 2025 Canadian consensus also defines the primary goals of treatment as disease stabilization and repigmentation.

Topical corticosteroids

It is one of the primary options that can be used in appropriate areas for localized vitiligo.

However, duration of use and application area are important; long-term use of strong steroids in sensitive areas like the face may not be suitable.

Topical calcineurin inhibitors

Tacrolimus and pimecrolmus can be evaluated especially on sensitive areas such as the face and neck.

It is among the basic topical treatment options in current international consensus.

Ruxolitinib cream

This is one of the significant new developments in vitiligo treatment.

The topical JAK inhibitor ruxolitinib is a targeted therapy that can be used to achieve repigmentation in certain patients with nonsegmental vitiligo.

The 2025 Canadian consensus considers ruxolitinib cream among topical treatment options; a 2026 updated review summarizes phase II–III randomized trial data supporting its efficacy.

However, indications for use, age limits, licensing status, and accessibility may vary by country; treatment plans should be developed taking into account current local licensing and safety information.

Phototherapy

Narrowband ultraviolet B (UVB) (NB-UVB) is one of the best-established treatment options for vitiligo.

It can be used alone or in combination, especially in more widespread disease or in patients who have not responded adequately to topical treatment.

The 2024 JAAD consensus defines current maintenance standards for NB-UVB.

Excimer laser or light

308 nm excimer systems may be considered for targeted phototherapy in more limited areas of vitiligo.

What matters is not the name of the device, but the correct indication and treatment principle.

Ruxolitinib + NB-UVB

This field is also developing rapidly.

Therefore, we won't exaggerate this and call it the "new standard.".

Rapidly progressing vitiligo

In active and rapidly progressing disease, the primary goal is to halt the loss of new pigment.

In selected patients, short-term systemic immunomodulatory approaches or options such as oral mini-pulse corticosteroids are being evaluated in current consensus.

These are not routine treatments for every vitiligo patient.

Surgical treatments

In selected cases of stable, localized vitiligo resistant to medical treatments, various surgical pigment cell transfer techniques may be evaluated.

However, surgical methods are not suitable for active disease.

The 2025 Canadian consensus considers surgical treatments as an option, particularly for stable and refractory localized disease.

Can vitiligo completely disappear?

To this question:

“"Yes, it will definitely pass."”

or

“"Nothing can be done."”

That kind of answer is incorrect.

Some patients can achieve quite successful repigmentation. Others may have a limited response.

Treatment response, especially:

the area where the lesion is located,

duration of illness,

pigment reserve in hair follicles,

disease activity

It can have an effect.

The face and neck generally respond better, while acral regions such as the fingertips and toes may respond less well.

Can the pigment disappear again after it returns?

Yes.

Relapse is possible in vitiligo.

Therefore, maintenance therapy may be considered for some patients after successful repigmentation. The 2025 Canadian consensus also states that maintenance therapy may help reduce the risk of recurrence.

Can people with vitiligo avoid sun exposure?

Because melanin is absent in areas affected by vitiligo, natural protection against sunburn is reduced.

Therefore, adequate photoprotection is important.

However, controlled NB-UVB phototherapy used for therapeutic purposes differs from everyday uncontrolled sun exposure.

We won't confuse the two.

Can vitiligo be cured through diet?

There is no specific diet proven to cure vitiligo.

If there are any identified nutritional deficiencies or other accompanying health problems, these will also be treated.

There is no reliable evidence to show that eliminating a specific food restores pigment in vitiligo.

Is it associated with other autoimmune diseases?

Yes.

It can be associated with certain autoimmune diseases, particularly autoimmune thyroid disorders.

However, instead of automatically administering a comprehensive autoimmune testing panel to everyone, evaluation should be based on history, family history, and clinical findings.

Is vitiligo psychologically significant?

Definitely.

Even though vitiligo is often asymptomatic physically, the loss of pigment in visible areas can seriously affect social life, self-image, and quality of life.

The fact that the Turkish validity study of the vitiligo-specific quality of life scale was presented at the 2024 National Dermatology Congress of the Turkish Dermatology Association shows that the psychosocial burden of the disease is also considered important in Turkish dermatology practice. (Turkish Dermatology Association)

When should you consult a dermatologist?

If new white areas are appearing,

If the spots are getting bigger,

If new regions are being added rapidly,

If graying occurs in the hair or body hair,

If it is not clear whether the diagnosis is actually vitiligo,

if disease in the face or visible areas affects quality of life

Dermatological evaluation is appropriate.
