Introduction

Vitiligo is a skin condition that causes patches of skin to lose their color. These patches may look lighter or even white compared to the rest of the skin. Vitiligo happens when the cells that give skin its color (called melanocytes) stop working or die. It can appear anywhere on the body, including the face, hands, arms, legs, and sometimes even inside the mouth or in the hair. While vitiligo doesn’t cause pain or make you sick, it can change the way someone looks, which may affect how they feel about themselves.

Causes and Risk Factors

Doctors don’t know exactly what causes vitiligo, but they do know a few important things:

• Immune system: Vitiligo is thought to be an autoimmune condition. This means the body’s immune system, which normally protects us from germs, mistakenly attacks the melanocytes.
• Family history: If someone in your family has vitiligo, you may be more likely to have it too.
• Other health conditions: People with thyroid disease, type 1 diabetes, or certain other autoimmune conditions are at higher risk.
• Not contagious: You cannot “catch” vitiligo from another person.

Diagnosing Vitiligo  

Vitiligo is usually diagnosed by a doctor looking closely at the skin. A dermatologist (skin specialist) may:

• Use a special light called a Wood’s lamp to see patches more clearly.
• Ask about family history or other health problems.
• Order blood tests to check for autoimmune conditions.

Most of the time, no biopsy or surgery is needed to confirm vitiligo.

Living with Vitiligo

Living with vitiligo can be challenging because the changes in skin color are visible. Some people may feel self-conscious or worried about what others think. Emotional support from family, friends, or support groups can make a big difference.

Sun protection is especially important. Areas of skin without pigment can burn more easily. Using sunscreen, wearing hats, and covering up with clothing helps protect the skin and prevent more contrast between normal and lighter patches.

People with vitiligo can still live healthy, active lives. The condition does not shorten life or cause pain, but it can affect confidence and mood.

Common symptoms

The main signs of vitiligo include:

• White or light patches on the skin that may grow or spread over time.
• Changes in hair color, such as white streaks in the scalp, eyelashes, or eyebrows.
• Patches inside the mouth where skin loses its normal color.

The patches may stay in one area, or they may spread to different parts of the body. For some people, the patches grow quickly, while for others, they change very slowly.

Management

There is no cure for vitiligo yet, but there are treatments that can help reduce the appearance of patches or slow the spread. Options include:

• Topical creams: Medicines that calm the immune system or help bring pigment back to the skin.
• Light therapy: Special lamps or controlled sunlight can sometimes encourage color to return.
• Oral medicines: In more serious cases, medicines that affect the immune system may be used.
• Surgical options: For some people, skin grafts or special tattooing (called micropigmentation) may help.
• Cosmetic options: Makeup and self-tanners can cover patches and even out skin tone.

Because vitiligo is different for everyone, treatment plans are often tailored to the individual.

Research and Progress

Scientists are working hard to better understand vitiligo and improve treatments. Research is focused on:

• Investigational medicines that moderate the immune system to keep from attacking pigment cells.
• Regrowing pigment cells in the skin.
• Better light therapies that are safer and more effective.
• Emotional support programs, since vitiligo can affect confidence and mental health.
