12. The bottom line

A small, chalk-white patch appears on the back of the hand, near the lips or around the eyes. At first it is easy to mistake for a fungal spot or dry skin, but it does not flake or itch, and it slowly becomes sharper and whiter. For many people in India, this moment brings a lot of fear, partly because of old myths and the stigma attached to white patches.

Vitiligo is not contagious, not caused by food, and not a sign of poor hygiene. This guide explains what it is, how to recognise it, how Ayurveda has described it, and what management can realistically achieve.

01What vitiligo is

Skin gets its colour from melanin, a pigment made by cells called melanocytes. In vitiligo, melanocytes in certain areas stop working or are destroyed, so those areas lose colour and turn white.

The main mechanism is autoimmune: the body's immune system mistakenly attacks its own pigment cells. Genetics play a part, and oxidative stress in the skin is thought to make melanocytes more vulnerable. Vitiligo affects roughly 0.5 to 2 percent of people worldwide, across all skin types, and it shows more clearly on darker skin.

02Types of vitiligo

• Non-segmental vitiligo is the most common form. Patches tend to appear on both sides of the body, often symmetrically, on the hands, feet, around the mouth and eyes, elbows, knees and skin folds. It can spread over years, with periods of stability.
• Segmental vitiligo affects one side or one area of the body. It often starts earlier in life, spreads for a while, and then tends to stabilise.
• Focal vitiligo is a few small patches in one area that may stay limited or later develop into one of the other types.

03Early signs

• Milky or chalk-white patches with fairly clear borders.
• Patches that do not scale, itch much or hurt.
• White or grey hair growing from a patch (on the scalp, eyebrows, eyelashes or beard).
• Loss of colour inside the mouth or on the lips.
• New patches at places of friction or injury, such as a cut, a tight waistband or a watch strap.
• This is called the Koebner phenomenon.

Other conditions can cause light patches, including fungal infections (tinea versicolor), post- inflammatory lightening, pityriasis alba and, rarely, leprosy. A dermatologist can usually tell the difference by examining the skin, sometimes with a Wood's lamp (ultraviolet light) that makes vitiligo patches glow bright white.

04The thyroid connection

Vitiligo is linked with other autoimmune conditions. The most common is autoimmune thyroid disease (Hashimoto's or Graves'). Some people may also have type 1 diabetes, pernicious anaemia (B12 deficiency due to an immune problem) or alopecia areata. Many dermatologists suggest a thyroid test when vitiligo is diagnosed, and again if symptoms like tiredness, weight change or feeling cold appear.

05How Ayurveda describes vitiligo

Ayurvedic texts describe white patches under the names shvitra and kilasa, and classify them within the broader group of skin disorders called kushtha. The descriptions involve all three doshas, with pitta and the blood and tissue layers (rakta, mamsa, meda) given importance. Classical texts also link the condition to diet and conduct, including viruddha ahara (incompatible food combinations), and some describe it as difficult to treat when it is long- standing, widespread or affecting hair.

Traditional management described in Ayurveda includes purification therapies (shodhana) under supervision, internal herbal formulations, applications on the skin and controlled sun exposure. The best-known herb is bakuchi (Psoralea corylifolia, also called babchi).

06An important caution about bakuchi

Bakuchi seeds contain psoralens, the same type of compound used in the older medical therapy PUVA (psoralen plus ultraviolet A). Psoralens make the skin highly sensitive to sunlight. This is why bakuchi was traditionally combined with sun exposure, but it is also why it can be dangerous at home:

• Applying bakuchi oil and then sitting in the sun can cause severe burns and blisters, which can trigger new patches.
• Oral bakuchi preparations have been linked to liver injury in published case reports.

Use bakuchi only under the supervision of a qualified Ayurvedic doctor who monitors your skin and liver, and never combine it with sun exposure on your own.

07What modern dermatology offers

A dermatologist chooses treatment based on how much skin is involved, where the patches are and whether the vitiligo is active or stable:

• Topical corticosteroid creams for limited patches, for a defined period.
• Calcineurin inhibitor creams (such as tacrolimus), often used on the face and skin folds.
• Narrowband UVB phototherapy, given in clinic sessions over months, for wider areas.
• Excimer laser or targeted light for small, stubborn patches.
• Newer creams called JAK inhibitors, which are approved for certain patients in some countries.
• Oral medicines for a short time to slow rapidly spreading vitiligo.
• Surgical grafting of pigment cells for patches that have been stable for a long time.

Results vary from person to person. The face and neck usually respond best. The hands, feet and lips respond least. Repigmentation, when it happens, is often slow and may be partial, and some patches can return. Being realistic about this protects people from expensive "guaranteed" treatments.

08Daily care that matters

1. Protect patches from the sun. Depigmented skin burns easily. Use a broad-spectrum sunscreen of SPF 30 or more, reapply every 2 to 3 hours outdoors, and cover up with clothing.
2. Avoid skin injury. Gentle handling of the skin, loose clothing and avoiding tight straps can reduce new patches at friction points.
3. Don't try harsh home applications. Lemon, raw bakuchi paste, chemicals or "burning" treatments can injure the skin and worsen vitiligo.
4. Camouflage is an option. Cosmetic cover creams designed for vitiligo can even out colour safely if you choose.
5. Look after general health. Sleep, stress management and treating thyroid problems all help overall wellbeing.
6. Track changes. Take photos of patches every few months in the same light to see whether they are stable or spreading.

09Does diet cause or cure vitiligo?

There is no good evidence that any specific food causes or cures vitiligo. The popular belief that eating fish with milk, sour foods or white foods causes white patches is not supported by research. A balanced diet is good for overall health, and some studies have looked at vitamin B12, folate, vitamin D and antioxidants, but the evidence is not strong enough to call any of them a treatment. Our separate Hindi post on diet goes into this in detail.

10When to see a dermatologist

• Any new white patch that does not go away.
• Patches spreading quickly over weeks.
• Patches near the eyes, lips or genitals.
• Symptoms of thyroid problems alongside new patches.
• Distress or low mood related to the skin.

11Frequently asked questions

12The bottom line

Vitiligo is an autoimmune skin condition, not an infection or a punishment for what you eat. Ayurveda describes it as shvitra and has long used approaches such as bakuchi, which must be used only with expert supervision. A dermatologist can offer creams, light therapy and, for stable patches, grafting. Sun protection, gentle skin care and realistic expectations matter as much as any treatment.
