Vitiligo is a chronic condition in which the skin loses melanocytes, the cells that give it color, leaving milky-white patches. The most widely accepted view is that it is an autoimmune condition: the immune system turns against the body’s own pigment cells. Because it is long-term, vitiligo treatment aims to bring the condition under control, slow the spread of patches and, where possible, help color return to some areas.

Vitiligo can start at any age, but it most often appears in childhood or early adulthood. It affects women and men of every skin tone. On darker skin the patches stand out more, so they tend to be noticed earlier.

Vitiligo is not contagious and does not directly threaten general health. Still, when it affects visible areas, it can weigh on self-confidence, social life and mood, and that side of the condition deserves attention too.

The main sign is a milky-white patch with clear borders. The patches usually do not hurt or itch. They most often appear on:

• The face: especially around the eyes, mouth and nose.
• Hands and feet: fingertips, the backs of the hands and the wrists.
• Skin folds: the underarms and groin.
• Areas exposed to friction: elbows, knees and the waistline.
• Hair-bearing areas: hair, eyebrows or eyelashes within a patch may turn white.

There are two main types. In the more common non-segmental vitiligo, patches appear on both sides of the body, usually symmetrically. In segmental vitiligo, they tend to stay in one area on one side of the body.

The exact cause is not known. Genetic tendency, the immune system and environmental factors are thought to act together, and the condition is more likely in people with a family history. In some people, skin injury, a bad sunburn or intense stress may trigger new patches. Vitiligo can occur alongside other autoimmune conditions, such as thyroid disease and alopecia areata.

Diagnosis and the treatment plan are made together with a dermatologist. Diagnosis is mostly based on examination; a special light called a Wood’s lamp may be used to see the patches more clearly, and blood tests may be requested to check for related conditions such as thyroid disease.

At our clinic in Nişantaşı, people who come in with suspected vitiligo are referred to a dermatologist for diagnosis and treatment. Once the diagnosis is made, we can support you with guidance on skincare and sun protection alongside your dermatology follow-up. Not every white patch is vitiligo: fungal infections and some other skin conditions can look similar.

Treatment depends on the type and extent of vitiligo, where the patches are, whether the condition is active and your age. The commonly known options include:

• Topical treatments: corticosteroid creams and calcineurin inhibitor creams, mainly for limited areas.
• Phototherapy: light treatments such as narrowband UVB, given in dermatology centers for widespread or progressing vitiligo.
• Oral medication: short courses may be considered by a doctor during fast-spreading phases.
• Surgical methods: for some patches that have stayed stable for a long time, pigment cell transplantation done in specialist centers may be an option.

Response varies from person to person, and results usually appear over months. The face and neck often respond better, while fingers and toes can be harder to treat. Because vitiligo is not a pigmentation spot, the lightening treatments used in skin spot treatments are not suitable for it.

Skin with vitiligo has no pigment, so the patches are much more sensitive to the sun. Good skincare protects the skin and may lower the risk of triggering new patches:

1. Use a broad-spectrum, high-SPF sunscreen every day on all sun-exposed areas.
2. Avoid sunburn, which can trigger new patches.
3. Avoid harsh scrubs, exfoliating mitts and vigorous rubbing.
4. Choose fragrance-free cleansers and moisturizers made for sensitive skin.
5. Watch for long-term friction from tight clothing, belts or jewelry.

If the look of the patches bothers you, camouflage makeup and self-tanning lotions can be temporary options; test them on a small area first. Tattoos, permanent makeup and other procedures that injure the skin may cause new patches in some people, so talk to your doctor before having them.

The course of vitiligo differs greatly from person to person. In some people, the patches stay the same for years; in others they spread slowly or quickly. The condition may alternate between calm periods and active periods when new patches appear.

Patches that increase quickly, edges that become blurred, or new patches in areas of friction may be signs of active disease. In these cases, a dermatology check-up should not be delayed.

Living with vitiligo can be emotionally hard. If you feel anxious or withdrawn, psychological support should be seen as an important part of care. Regular dermatology follow-up, sun protection and healthy habits work together to keep the condition under control over the long term.
