Vitiligo: Causes, Symptoms, and Treatment Options

Vitiligo is a chronic skin condition that causes patches of skin to lose their natural color. These white or light-colored patches appear when the cells responsible for producing skin pigment stop functioning or die . The condition affects people of all skin types, though it is often more noticeable in individuals with darker skin tones .

Understanding vitiligo is important not just for those who have it, but for society as a whole. The condition is not life-threatening or contagious, yet it can cause significant emotional distress and impact quality of life . The visible nature of the condition often leads to misunderstandings and social challenges for those affected.

Recent years have brought exciting developments in vitiligo treatment. In 2026, the National Institute for Health and Care Excellence (NICE) recommended the first licensed treatment for vitiligo on the NHS, bringing hope to thousands of people in the United Kingdom . This milestone represents a major step forward in managing this challenging condition.

Quick Facts

What Is Vitiligo?

Vitiligo (pronounced vit-ih-LIE-go) is a disease that causes loss of skin color in patches. The discolored areas usually get bigger over time. The condition can affect the skin on any part of the body, and it can also affect hair and the inside of the mouth .

Normally, the color of hair and skin is determined by melanin, a pigment produced by cells called melanocytes. Vitiligo occurs when these melanocytes die or stop functioning . The involved patches of skin become lighter or white because melanin production stops.

The condition is generally considered to be an autoimmune disorder . Autoimmune disorders occur when the immune system mistakenly attacks the body’s own tissues and organs. In people with vitiligo, the immune system appears to attack and destroy the pigment cells in the skin .

Types of Vitiligo

Vitiligo can present in several different forms. The type of vitiligo a person has affects how the condition progresses and which parts of the body are involved.

Generalized Vitiligo (Nonsegmental)

This is the most common form of vitiligo. In generalized vitiligo, discolored patches appear on many parts of the body. The patches often progress symmetrically, meaning they appear on corresponding body parts on both sides . Depigmentation typically occurs on the face, neck, scalp, and around body openings such as the mouth and genitals .

Segmental Vitiligo

Segmental vitiligo is less common, occurring in about 10 percent of affected individuals . This form is associated with smaller patches of depigmented skin that appear on one side of the body in a limited area . It tends to occur at a younger age, progress for a year or two, then stop .

Universal Vitiligo

In this rare form, discoloration affects nearly all skin surfaces . This is the most extensive type of vitiligo, with depigmentation covering more than 80 percent of the total body surface .

Acrofacial Vitiligo

This type affects the face and hands, as well as areas around body openings such as the eyes, nose, and ears . The involved sites are usually limited to the face, head, hands, and feet .

Localized (Focal) Vitiligo

In this type, only one or a few areas of the body are affected . The patches are small and isolated, and they may not evolve into a more widespread form for at least two years .

Causes and Risk Factors

The exact cause of vitiligo remains unknown, but researchers have identified several factors that may contribute to its development.

Autoimmune Factors

The most widely accepted theory is that vitiligo is an autoimmune disorder . In this scenario, the body’s immune system mistakenly attacks and destroys the melanocytes in the skin . This destruction is thought to be due to an autoimmune problem, though the exact trigger is unclear.

Up to 30 percent of patients have other autoimmune antibodies or clinical autoimmune endocrinopathies . These can include antibodies to thyroglobulin, adrenal cells, and parietal cells. The strongest association is with Graves disease and Hashimoto thyroiditis .

Hereditary Factors

Genetics play a role in vitiligo. The condition tends to run in families, with about 30 percent of people with vitiligo having a family history of the condition . It can be familial with autosomal dominant inheritance with incomplete penetrance and variable expression .

Trigger Events

Some people report that vitiligo appeared after a specific event. These trigger events may include:

• Physical injury to the skin, such as sunburn or chemical burns 

• Emotional stress 

• Exposure to certain chemicals found in household products and dyes 

• Immunotherapy for melanoma, including BRAF inhibitors and PD-1 inhibitors, can trigger vitiligo as an immunologic side effect 

Associated Conditions

About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder . These may include:

• Autoimmune thyroid disease

• Rheumatoid arthritis

• Type 1 diabetes

• Psoriasis

• Pernicious anemia

• Addison disease

• Systemic lupus erythematosus

• Celiac disease

• Crohn’s disease

• Ulcerative colitis 

Common Symptoms

The primary symptom of vitiligo is the appearance of white or light-colored patches on the skin. These patches typically have certain characteristics.

Skin Changes

The patches of vitiligo are flat areas of normal-feeling skin without any pigment . They often have well-defined but irregular borders and may have a darker border around the edges . The patches most often affect:

• The face

• Elbows and knees

• Back of the hands and feet

• Genitals

• Areas with skin folds, such as armpits 

Hair Changes

Vitiligo can also affect hair color. Signs include premature whitening or graying of the hair on the scalp, eyelashes, eyebrows, or beard .

Mucous Membrane Involvement

Loss of color can also occur in the tissues that line the inside of the mouth and nose .

When to See a Doctor

It’s important to see a health care provider if areas of skin, hair, or mucous membranes lose coloring . While vitiligo has no cure, treatment might stop or slow the discoloring process and return some color to the skin .

Diagnosis and Testing

Diagnosing vitiligo typically involves a physical examination by a health care provider.

Physical Examination

A doctor can usually diagnose vitiligo by examining the skin. The appearance of the patches, particularly their well-defined borders and distribution pattern, often makes the condition recognizable .

Wood’s Lamp Examination

Sometimes, the provider uses a Wood’s lamp, which is a handheld ultraviolet light. Under this light, the areas of skin with less pigment glow bright white, making them easier to identify .

Additional Tests

In some cases, additional tests may be performed:

• Skin biopsy to check for other causes of pigment loss 

• Blood tests to check levels of thyroid or other hormones, glucose, and vitamin B12 to check for other associated disorders 

Treatment Options

Treatment for vitiligo aims to restore color to affected skin, even out skin tone, or stop the disease from progressing. The choice of treatment depends on factors such as age, how much skin is involved, how quickly the disease is progressing, and how it’s affecting a person’s life .

Medications

Several medications can help restore some skin color.

Topical corticosteroids: Applying a corticosteroid cream to affected skin might return color. This is most effective when vitiligo is still in its early stages. It’s effective and easy to use, but it may take several months to see changes. Possible side effects include skin thinning or the appearance of streaks on the skin .

Calcineurin inhibitors: Ointments such as tacrolimus (Protopic) or pimecrolimus (Elidel) might be effective for people with small areas of depigmentation, especially on the face and neck . Unlike steroids, these do not cause skin thinning .

Ruxolitinib (Opzelura): This is a Janus kinase (JAK) inhibitor that blocks certain enzymes in the immune system. The FDA approved this medicine to help restore skin color in people with vitiligo aged 12 and older . In February 2026, NICE recommended it for NHS use .

Light Therapy

Phototherapy with narrow band ultraviolet B (UVB) has been shown to stop or slow the progression of active vitiligo. It may be more effective when used with corticosteroids or calcineurin inhibitors. Treatment requires two to three sessions per week, and it may take 1 to 3 months before changes are noticeable .

PUVA therapy combines a plant-derived substance called psoralen with UVA light. This approach is effective but has been largely replaced in many practices by narrow band UVB therapy because it is easier to administer .

Surgery

If light therapy and medications haven’t worked, some people with stable disease may be candidates for surgery.

Skin grafting: This involves transferring very small sections of healthy, pigmented skin to areas that have lost pigment .

Blister grafting: In this procedure, the doctor creates blisters on pigmented skin, usually with suction, and then transplants the tops of the blisters to discolored skin .

Cellular suspension transplant: The doctor takes tissue from pigmented skin, puts the cells into a solution, and transplants them onto the prepared affected area. Results can start showing up within four weeks .

Depigmentation

This therapy may be an option if vitiligo is widespread and other treatments haven’t worked. A depigmenting agent is applied to unaffected areas of skin, gradually lightening it to blend with discolored areas. The therapy is done once or twice daily for nine months or longer. Depigmentation is permanent .

Skin Camouflage

Makeup and self-tanning products can help minimize differences in skin color. Camouflage creams are waterproof and can last up to 4 days on the body and 12 to 18 hours on the face . Self-tanners containing dihydroxyacetone are approved by the FDA .

The Role of JAK Inhibitors

The development of JAK inhibitors represents a major advance in vitiligo treatment. These medications target the underlying immune response responsible for destroying melanocytes.

How JAK Inhibitors Work

The Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway is a central driver of immune-mediated melanocyte destruction . This pathway is activated by key cytokines involved in vitiligo, including interferon gamma (IFN-γ) and interleukin 15 (IL-15), which sustain cytotoxic T cell infiltration and melanocyte apoptosis . JAK inhibitors block this pathway, helping to stop the immune attack on pigment cells.

Approved Treatments

Topical ruxolitinib is a JAK1/2 inhibitor that has demonstrated consistent and clinically meaningful repigmentation, particularly in facial lesions. It is approved for use in both adolescents and adults .

Emerging Therapies

Several oral JAK inhibitors are currently under investigation for vitiligo:

• Ritlecitinib (JAK3/TEC inhibitor)

• Upadacitinib (JAK1 inhibitor)

• Povorcitinib (JAK1 inhibitor)

These agents have shown promising efficacy either as monotherapy or in combination with phototherapy. Ongoing phase III trials are expected to further define their role in clinical practice .

Safety Considerations

JAK inhibitors have variable safety profiles depending on selectivity, formulation, and dose. Topical agents are generally well tolerated with minimal systemic absorption, whereas oral JAK inhibitors require monitoring due to potential risks of infection, hematologic abnormalities, and cardiovascular events .

Living with Vitiligo

Living with vitiligo involves both physical and emotional considerations. Several strategies can help people manage the condition effectively.

Sun Protection

People with vitiligo are at greater risk of sunburn because their skin lacks pigment that provides natural protection . Use a broad-spectrum, water-resistant sunscreen with an SPF of at least 30. Apply generously and reapply every two hours or more often if swimming or sweating .

Seek shade, wear protective clothing, and avoid tanning beds and sunlamps. Sunscreen also minimizes tanning, which accentuates the vitiligo patches .

Vitamin D Supplementation

If the skin is not exposed to the sun, there’s an increased risk of vitamin D deficiency. Sunlight is the main source of vitamin D, though a form is also found in some foods. A daily supplement containing 10 micrograms of vitamin D is recommended .

Avoid Tattoos

Damage to the skin, such as that caused by a tattoo, may cause a new patch of vitiligo to appear within two weeks .

Emotional Support

Vitiligo can cause significant emotional distress. Some people develop low self-esteem or a poor self-image from concerns about their appearance . Support groups and counseling can help . Charities such as The Vitiligo Society can put people in touch with local support groups .
