12419 Vitiligo

Overview

Vitiligo is a long-term skin condition that causes patches of skin to lose their natural color, leaving white patches. It happens when the cells that make pigment (color) in the skin stop working or die.

Vitiligo is fairly common. Around 1 in 100 people worldwide has it.

It can start at any age, but it often appears before age 30. It affects people of all skin types and ethnicities.

Symptoms

Common symptoms

• White, irregularly shaped patches on the skin, often first noticed on the hands, face, or around body openings
• Hair turning white or grey on the scalp, eyebrows, eyelashes, or beard
• Patches that are pale at first and gradually become completely white
• In fair skin, patches may appear as areas that simply don't tan

Symptoms in children

• Children often get patches around the mouth, eyes, fingers, knees, or elbows
• Patches may appear and grow for a while, then pause for months or years

Symptoms in older adults

• Older adults may notice vitiligo patches alongside other age-related skin changes
• Patches may be more noticeable on skin that has thinned or aged, but the condition itself behaves similarly

Causes

Main causes

• Vitiligo is an autoimmune condition. The body's immune system mistakenly attacks the cells that create skin pigment.
• Genes play a part; it sometimes runs in families.
• A trigger such as severe stress, skin damage, or a viral illness may bring it on in people who are already at risk.
• It is not caused by anything you did or didn't do.

Risk factors

• A family member with vitiligo
• Another autoimmune condition, such as thyroid problems, alopecia areata, or type 1 diabetes
• Certain genetic variations that make the immune system more likely to target pigment cells

When to see a doctor

See a doctor urgently if:

• If you see a new white patch and aren't sure what it is, get it checked within a few days.
• Seek urgent advice if the skin in a patch becomes painful, itchy, or starts to blister.

Book a routine appointment if:

• Make a routine appointment if you notice white patches that persist for more than a couple of weeks.
• If you also have extreme tiredness, weight changes, or sensitivity to cold, mention these to your doctor.

Diagnosis

A doctor can often diagnose vitiligo by looking at your skin with a special ultraviolet light called a Wood's lamp, which makes the patches clearer. They will also ask about your family history and check for other autoimmune signs.

Tests that may be done

• Examination with a Wood's lamp (ultraviolet light)
• A small skin biopsy (taking a tiny skin sample) if the diagnosis is unclear
• Blood tests to check thyroid function and look for other autoimmune conditions

What to expect at your appointment

The visit usually takes 15–30 minutes. The doctor will gently examine your skin and ask questions. You don't need to prepare in advance. You can ask a friend or family member to come with you for support.

Treatment

There is no cure for vitiligo, but treatment can help even out skin tone and may bring back some color. Treatment often works best when started early. Not everyone needs treatment — some people choose to leave the patches as they are.

Self-care at home

• Use a broad-spectrum sunscreen (SPF 30 or higher) on all exposed skin, including vitiligo patches, to prevent sunburn.
• Use camouflage cosmetics to cover patches if you like; a pharmacist or a cosmetics specialist can help you choose a good match.
• Protect your skin from cuts, scrapes, and harsh chemicals that may trigger new patches.
• Ask your doctor about vitamin D, especially if you are avoiding sun exposure.

Medical treatments

Medical treatments aim to restore color and are chosen by a specialist. They may include topical treatments (creams or ointments) that help pigment return, light therapy that carefully exposes patches to ultraviolet light, and other procedures such as depigmentation, which lightens remaining normal skin so it blends with the white patches. A dermatologist will discuss what is appropriate for your situation.

When is surgery considered?

Surgery, such as transferring small areas of healthy skin to a vitiligo patch, is sometimes offered when other treatments have not worked. It is only suitable for certain people whose vitiligo is stable, and it should only be done after a full discussion with a skin specialist.

Living with this condition

Living with vitiligo is different for everyone. You may want to take extra care with sun protection, choose clothing that makes you feel comfortable, and use makeup or self-tanning products if you wish. The most important thing is to do what feels right for you.

Lifestyle tips

• Wear sunscreen daily and reapply it often when outdoors.
• Eat a balanced diet with plenty of fruit, vegetables, and foods rich in antioxidants. There is no special diet that cures vitiligo.
• Manage stress with activities you enjoy, such as walking, meditation, or talking to friends.
• Avoid tanning beds, which increase skin cancer risk and do not help vitiligo.

Diet and exercise

No food has been proven to treat vitiligo, but a healthy, varied diet supports your immune system. Regular exercise helps you feel well and reduces stress. If you are worried about vitamin D, ask your doctor about supplements.

Mental health and emotional wellbeing

Vitiligo can affect confidence, especially when patches are on visible areas. Feeling anxious, sad, or embarrassed is understandable. If it affects your mood or quality of life, talk to a healthcare professional. You can also contact a mental health support service — help is available.

Prevention

There is no known way to prevent vitiligo, because it is caused by an immune reaction you cannot control. You can reduce the risk of new patches after skin injury by protecting your skin from cuts, scrapes, and sunburn.

Vaccines

There is no vaccine for vitiligo. Like everyone, keep your recommended vaccinations up to date to protect your overall health.

Screening programmes

There is no routine screening test for vitiligo. If you have another autoimmune condition, your doctor may check your thyroid health over time.

Complications

If left untreated

• Patches may spread over time or stay the same — the course is unpredictable.
• People with vitiligo have a higher chance of sunburn on affected areas and need to take extra sun care.
• Vitiligo is linked with a higher risk of other autoimmune conditions, such as thyroid disease.

Long-term outlook

Vitiligo is a lifelong condition, but many people live comfortably with it. Patches may change over the years, and treatment sometimes restores color. There is no serious harm to your physical health from the patches themselves, and with the right support, most people adapt and feel confident.
