What Is Vitiligo? Causes, Types & Treatment (2026 Guide)

What Is Vitiligo? {#what-is-vitiligo}

Vitiligo is a chronic skin condition in which the skin loses its natural colour in patches. These pale or white patches appear when the cells responsible for producing skin pigment — called melanocytes — are destroyed or stop functioning. The result is a loss of melanin, the pigment that gives skin, hair, and eyes their colour.

Vitiligo is not contagious. You cannot catch it from another person through touch, contact, or any form of transmission. It is also not caused by poor hygiene. Yet despite being medically well-understood, vitiligo carries significant social stigma in India — especially in Hyderabad and across Telangana — that can profoundly affect a person’s confidence and quality of life.

The white patches can appear anywhere on the body. They may be small at first and expand over time, or they may stay stable for years. For some people, the condition affects a small area; for others, it spreads across large portions of the body.

Dr. Abdul Adal’s Note: “Vitiligo is not just a cosmetic concern. It is a medical condition with immunological, genetic, and psychological dimensions. Patients deserve accurate information and compassionate, evidence-based care.”

How Common Is Vitiligo? {#how-common}

Vitiligo affects approximately 0.5% to 2% of the global population — roughly 50 to 100 million people worldwide. In India, prevalence estimates range between 0.5% and 4%, with higher rates reported in certain regions including Gujarat, Rajasthan, and parts of Andhra Pradesh and Telangana.

Key statistics:

• Vitiligo can begin at any age, but most people first notice it before the age of 30.
• It affects all skin tones equally, though it is most visible — and often most distressing — in people with darker complexions.
• Approximately 20% of people with vitiligo have at least one family member with the condition.
• About 30% of vitiligo patients have an associated autoimmune condition such as thyroid disease, type 1 diabetes, or alopecia areata.

What Causes Vitiligo? {#causes}

Vitiligo occurs when melanocytes — the pigment-producing cells in the skin — are damaged, destroyed, or fail to function. The exact reason this happens is not fully understood, but research points to several interacting causes.

1. Autoimmune Dysfunction

The most widely accepted explanation is that vitiligo is an autoimmune disorder. In people with vitiligo, the immune system mistakenly identifies melanocytes as foreign or harmful and attacks them. This immune response destroys the very cells responsible for skin colouration.

Evidence supporting this includes the frequent association of vitiligo with other autoimmune diseases such as:

• Hashimoto’s thyroiditis and Graves’ disease
• Type 1 diabetes mellitus
• Alopecia areata (patchy hair loss)
• Rheumatoid arthritis
• Lupus

2. Genetic Factors

Vitiligo has a clear genetic component. Multiple genes have been linked to vitiligo susceptibility, many of which are involved in immune regulation. Having a first-degree relative with vitiligo significantly increases your risk, though having the genes does not guarantee you will develop the condition.

3. Oxidative Stress

In people with vitiligo, melanocytes appear more vulnerable to oxidative stress — damage from unstable molecules called free radicals. Accumulation of hydrogen peroxide in the skin has been observed in vitiligo patches, suggesting that environmental or metabolic stress may trigger or worsen melanocyte destruction.

4. Neural Factors

In segmental vitiligo specifically, it is thought that abnormal nerve function in certain skin regions may cause the release of toxic substances that damage nearby melanocytes. This may explain why segmental vitiligo follows nerve distribution patterns (dermatomes).

5. Triggers That May Activate or Worsen Vitiligo

Even in genetically predisposed individuals, certain triggers can initiate or accelerate the condition:

• Sunburn or skin trauma — the Köbner phenomenon, where vitiligo appears at sites of physical injury
• Emotional stress or psychological trauma
• Exposure to certain chemicals — including industrial phenols and rubber compounds
• Inflammatory skin conditions
• Hormonal changes — puberty, pregnancy, or thyroid imbalance

Types of Vitiligo {#types}

Understanding the type of vitiligo a patient has is essential for choosing the right treatment. Dr. Abdul Adal classifies and treats all recognised forms of vitiligo.

1. Generalised Vitiligo (Non-Segmental Vitiligo / NSV)

This is the most common form, accounting for approximately 85–90% of all vitiligo cases. Also called bilateral or symmetric vitiligo, it tends to appear on both sides of the body in similar locations — both hands, both knees, around both eyes.

Subtypes of generalised vitiligo include:

• Acrofacial Vitiligo — affects the face, hands, and feet; particularly around the eyes, mouth, fingers, and toes
• Vitiligo Vulgaris (Common Vitiligo) — scattered patches across various body areas
• Mixed Vitiligo — a combination of segmental and non-segmental patterns
• Universal Vitiligo — an advanced form where depigmentation affects more than 80% of the body surface

2. Segmental Vitiligo

Segmental vitiligo is less common (around 10–15% of cases) but behaves very differently. It appears on one side of the body and tends to follow a dermatomal or quasi-dermatomal distribution — corresponding to nerve pathways in the skin.

Key characteristics:

• Typically begins in childhood or adolescence
• Spreads rapidly at first, then stabilises
• Less likely to respond to systemic immunosuppressive treatments
• May be treated effectively with melanocyte transplantation (surgical repigmentation) once it stabilises

3. Focal Vitiligo

One or a few isolated patches that remain in a limited area without spreading. This form may represent early vitiligo or remain localised indefinitely.

4. Mucosal Vitiligo

Vitiligo that primarily affects the mucous membranes — inside the mouth, the lips, and the genitalia. It can occur alone or alongside skin involvement.

5. Trichrome Vitiligo

A transitional form in which patches show three distinct zones of colour: white (fully depigmented), tan (partially depigmented), and normal skin. This intermediate zone reflects an active or evolving process of melanocyte loss.

6. Inflammatory Vitiligo

A rare variant in which depigmented patches are bordered by raised, red, or inflamed edges, indicating active immune activity at the margin of the lesion.

Signs & Symptoms {#symptoms}

The hallmark sign of vitiligo is white or milky patches on the skin. However, the full picture includes several features that help doctors like Dr. Abdul Adal assess severity and activity.

Common signs include:

• Milky-white or chalk-white patches — the defining feature; completely devoid of pigment
• Premature whitening of hair — including scalp hair, eyebrows, eyelashes, and beard (a sign called poliosis)
• Loss of colour inside the mouth — affects the gums, inner lips, or palate
• Change in eye colour — the retina may lose pigment in some cases
• Köbner phenomenon — new patches appearing at sites of cuts, scrapes, or sunburn
• Hypersensitivity to sun — depigmented skin burns more easily without melanin’s protective function

What vitiligo does NOT cause:

• Pain or physical discomfort in the patches (unless sunburned)
• Itching (occasionally mild itching may signal active spreading)
• Any internal organ damage directly from the skin condition

Who Is at Risk? {#risk-factors}

Anyone can develop vitiligo, but certain factors increase the likelihood:

---

How Is Vitiligo Diagnosed? {#diagnosis}

Vitiligo is primarily a clinical diagnosis — it is usually identified through careful visual examination by a trained dermatologist. However, additional investigations help confirm the diagnosis, identify associated conditions, and guide treatment.

Clinical Examination

An experienced specialist like Dr. Abdul Adal will examine the pattern, distribution, and borders of the patches. The edges of active vitiligo are often poorly defined (“fuzzy”), while older, stable patches may have sharper borders.

Wood’s Lamp Examination

A Wood’s lamp emits UV light at a specific wavelength (365 nm). Under this lamp, vitiligo patches fluoresce bright white or blue-white, making early or subtle lesions visible that may be missed in normal light — especially in lighter-skinned individuals.

Dermoscopy

Dermoscopy (magnified examination of the skin) reveals patterns in the depigmented and perifollicular areas that help differentiate vitiligo from other causes of skin lightening such as pityriasis alba, tinea versicolor, or post-inflammatory hypopigmentation.

Blood Tests

Since vitiligo is associated with autoimmune conditions, blood tests are often recommended:

• Thyroid function tests (TSH, Free T3, Free T4)
• Thyroid antibodies (anti-TPO, anti-thyroglobulin)
• Fasting blood glucose / HbA1c — to screen for diabetes
• Complete blood count
• Vitamin B12 levels — deficiency is more common in vitiligo patients

Skin Biopsy

Rarely required for diagnosis, but may be performed in atypical or ambiguous cases to confirm the absence of melanocytes histologically.

Vitiligo Treatment Options {#treatment}

There is no single cure for vitiligo, but significant repigmentation is achievable for most patients with the right combination of treatments. Dr. Abdul Adal, with over 38 years of experience treating vitiligo in Hyderabad, tailors every treatment plan to the individual — considering the type, extent, location, activity, skin type, and the patient’s personal goals.

1. Topical Treatments

Topical Corticosteroids The first-line treatment for localised vitiligo, especially in children. Applied directly to patches, they suppress the localised immune response and stimulate repigmentation. Potency is chosen based on body area, and long-term use requires monitoring for skin thinning.

Topical Calcineurin Inhibitors (Tacrolimus / Pimecrolimus) These are steroid-sparing agents that modulate the immune response without the skin-thinning side effects of steroids. Particularly useful for sensitive areas such as the face, eyelids, and genital region.

Topical JAK Inhibitors (Ruxolitinib Cream) One of the most significant advances in vitiligo therapy in recent years. Ruxolitinib cream works by blocking the JAK-STAT signalling pathway that drives the autoimmune attack on melanocytes. Clinical trials have demonstrated meaningful facial and body repigmentation.

Topical PUVA (Psoralen + UVA) A photosensitising cream or solution (psoralen) is applied to patches before UVA light exposure. More commonly used for focal or limited vitiligo.

---

2. Phototherapy (Light-Based Treatment)

Narrowband UVB (NB-UVB) Phototherapy NB-UVB is the gold standard phototherapy for widespread vitiligo. The skin is exposed to a carefully calibrated narrow wavelength of ultraviolet B light (311–313 nm), which suppresses the immune attack and stimulates melanocyte migration and pigmentation.

• Sessions are typically 2–3 times per week
• Best results are seen over 6–12 months of consistent treatment
• Effective for all body areas including the trunk, limbs, and face
• Safe for children and during pregnancy (under specialist supervision)

Excimer Laser (308 nm) A targeted laser that delivers high-intensity UVB light precisely to depigmented patches without affecting surrounding normal skin. Ideal for localised or facial vitiligo and often produces faster results than full-body NB-UVB.

Oral PUVA Psoralen tablets are taken orally before UVA light exposure. Used for widespread vitiligo, it is less common today given the superior safety profile of NB-UVB.

---

3. Systemic Treatments

Oral Corticosteroids (Mini-pulse therapy) Low-dose oral steroids given in a short pulse regimen (e.g., betamethasone on two consecutive days per week) can halt the rapid spread of active vitiligo. It is particularly useful during flare-ups when new patches are appearing rapidly.

Oral JAK Inhibitors (Ruxolitinib, Tofacitinib, Baricitinib) Oral JAK inhibitors are an exciting frontier in vitiligo treatment, showing promise especially for widespread or rapidly progressing disease. As with all systemic medications, careful patient selection and monitoring are essential.

Vitamin D Supplementation Vitamin D deficiency is commonly observed in vitiligo patients. Supplementation may support immune regulation and enhance the response to phototherapy.

---

4. Surgical Treatments

Surgical repigmentation is suitable for stable, non-spreading vitiligo — typically after the disease has shown no new patches or expansion for at least 6–12 months.

Split-Thickness Skin Grafting Thin slices of normal pigmented skin are transplanted to depigmented areas. Effective for localised patches, though it leaves donor site scars and colour matching may be imperfect.

Suction Blister Grafting A suction device creates a blister on normal skin; the blister roof (containing melanocytes) is harvested and applied to a prepared vitiligo patch. Less traumatic than traditional grafting with excellent cosmetic results.

Melanocyte-Keratinocyte Transplantation Procedure (MKTP) Cells are harvested from normal skin, processed in the laboratory, and applied in suspension to a large depigmented area. This technique can treat larger surface areas in a single session with minimal scarring.

Follicular Unit Transplantation (FUT) for Hair-Bearing Areas For segmental vitiligo affecting the scalp or beard, hair follicle grafts containing melanocytes can be transplanted to repigment the area.

---

5. Camouflage & Supportive Measures

Medical Camouflage Specialist camouflage makeup or self-tanning products (containing DHA) can help patients manage visible patches on the face and hands while undergoing medical treatment. These are particularly valuable for special occasions and in managing psychosocial impact.

Sunscreen Daily broad-spectrum sunscreen (SPF 30+) is essential for vitiligo patients. Depigmented skin has no melanin protection and burns easily, and sunburn can trigger the Köbner phenomenon, causing new patches.

Depigmentation (for Universal Vitiligo) In patients where vitiligo covers more than 50–80% of the body and repigmentation is not feasible, depigmentation of the remaining normal skin with agents like monobenzone (monobenzyl ether of hydroquinone) or Q-switched laser can achieve an even, uniform skin tone.

Treatment Selection: What Factors Matter?

Living With Vitiligo {#living-with-vitiligo}

The psychological impact of vitiligo is real and significant, particularly in a society where skin colour carries deep social meaning. Studies consistently show that vitiligo is associated with higher rates of:

• Low self-esteem and body image concerns
• Social anxiety and avoidance
• Depression
• Reduced quality of life, particularly in women and adolescents

Dr. Abdul Adal’s clinic takes a holistic approach. Beyond prescribing treatment, we take time to listen, educate, and support patients and families through the emotional dimensions of living with vitiligo.

Practical tips for patients:

• Seek early treatment — the earlier intervention begins, especially in active spreading vitiligo, the better the outcome
• Be consistent — phototherapy and topical treatments require commitment over months for results to appear
• Protect your skin — daily sunscreen, protective clothing, and avoiding known triggers
• Connect with others — vitiligo support communities in India can provide solidarity and practical advice
• Manage stress — mindfulness, exercise, and mental health support are legitimate parts of vitiligo management
• Educate those around you — vitiligo is not infectious; helping family and friends understand this reduces stigma at home

Vitiligo FAQs {#faqs}

Q: Is vitiligo contagious? No. Vitiligo cannot be spread through skin-to-skin contact, shared clothing, water, or any form of transmission. It is an internal immune process specific to the individual.

Q: Can vitiligo spread to cover the whole body? In some individuals, particularly those with the universal subtype, vitiligo can spread extensively. However, many patients maintain stable, localised patches for years or decades. Early treatment can slow or stop spreading.

Q: Can vitiligo be cured completely? There is no universally guaranteed cure, but many patients achieve excellent repigmentation — sometimes 90–100% in affected areas — with modern treatments including NB-UVB, JAK inhibitors, and surgical procedures. The outcome depends on the type, location, and duration of vitiligo.

Q: Is vitiligo hereditary? Vitiligo has a genetic component. Having a family member with vitiligo increases your risk, but the majority of people with the predisposing genes do not develop the condition. It requires a combination of genetic susceptibility and environmental or immunological triggers.

Q: At what age does vitiligo typically start? Vitiligo can begin at any age, from infancy to old age. However, the peak age of onset is between 10 and 30 years. Segmental vitiligo more commonly begins in childhood.

Q: Are there foods to avoid with vitiligo? There is no scientifically proven “vitiligo diet.” However, some practitioners suggest reducing vitamin C-rich foods before phototherapy sessions (as vitamin C may reduce photosensitivity). Adequate intake of antioxidants, copper, zinc, and B vitamins supports skin health. Discuss dietary advice with your specialist.

Q: Does stress cause vitiligo? Stress does not directly cause vitiligo, but it can trigger the onset in genetically susceptible individuals and worsen or accelerate spreading in existing cases. Stress management is a legitimate component of comprehensive vitiligo care.

Q: Is vitiligo associated with any serious medical conditions? Vitiligo itself does not damage internal organs. However, it is associated with autoimmune conditions — particularly thyroid disorders — that do require medical management. All vitiligo patients should be screened for thyroid disease and diabetes.

Q: How long does treatment take to show results? Phototherapy and topical treatments typically show initial signs of repigmentation — small dots of colour reappearing in the patch — within 3 to 6 months of consistent treatment. Full repigmentation may take 12 to 24 months. Surgical procedures can produce results within weeks of the procedure.

Q: Is vitiligo treatment available in Hyderabad? Yes. Dr. Abdul Adal’s clinic at psoriasisandvitiligospecialist.com offers comprehensive vitiligo diagnosis and treatment in Hyderabad, including NB-UVB phototherapy, excimer laser, topical therapies, JAK inhibitor therapy, surgical repigmentation, and psychological support.
