Vitiligo is a long-lasting skin condition that causes some areas of skin to lose their natural color. This happens when the cells that make pigment, called melanocytes, stop working or are destroyed.
Because of this, white or lighter patches can show up anywhere on the body. Vitiligo can also affect hair, eyebrows, eyelashes, and even the inside of the mouth.*
Although vitiligo affects just over 1% of people worldwide, many still have questions about it. People often wonder what causes vitiligo, if it will spread, and whether it is dangerous. Learning about the condition can help you feel more confident in recognizing symptoms and getting the right treatment.
What Are the Signs of Vitiligo?
A common sign of vitiligo is lighter or completely white patches of skin. These patches usually develop slowly and often start in places that get more sun or experience more rubbing.
Common areas affected include:
- Hands and fingers
- Face
- Around the eyes or mouth
- Armpits
- Groin area
- Wrists
- Inside the mouth
Vitiligo can affect more than just the skin. Some people also notice their hair turning white or gray on the scalp, beard, eyelashes, or eyebrows.
Vitiligo can look different for everyone. Some people have just a few small spots, while others get larger patches in different areas. Many people ask if vitiligo will spread. This depends on the person. Sometimes, the patches stay the same for years. Other times, the lighter areas slowly spread.
What Causes Vitiligo?
Researchers are still figuring out the exact cause of vitiligo, but most agree it is an autoimmune disease. This means the body’s immune system mistakenly attacks healthy melanocytes, which give your skin, hair, and eyes their color. There are two main types of vitiligo:
Segmental Vitiligo
This type usually affects just one side or one area of the body. It often starts earlier in life and may change briefly before returning to the same state.
Non-Segmental Vitiligo
This is the more common type. It often shows up on both sides of the body, like both hands or both knees. Factors that may increase the risk of developing vitiligo include:
- A family history of vitiligo
- Severe sunburns
- Emotional stress
- Skin injuries or trauma
- Exposure to certain chemicals
- Other autoimmune diseases
People who have autoimmune conditions like thyroid disease, rheumatoid arthritis, diabetes, or alopecia areata may be more likely to develop vitiligo.
People also often ask whether vitiligo is genetic. Research shows that genetics might play a role, but vitiligo is not always inherited. About 30% of cases may be related to family history. Having a relative with vitiligo can raise your risk, but it does not mean that you will definitely get it.
Is Vitiligo Dangerous?
Vitiligo itself is not dangerous or contagious. You cannot “catch” it from another person, and it does not spread. You cannot catch it from someone else, and it does not harm your organs. Still, it can affect a person’s life in other ways. This means people with vitiligo are more likely to experience sunburn and sun damage if they are not careful with sun protection.
Vitiligo can also affect how people feel about themselves. Visible skin changes can sometimes cause embarrassment, anxiety, or lower self-esteem, especially if the patches are on the face or hands. Support from family, friends, counselors, and doctors can really help.
Sometimes, vitiligo is linked to other autoimmune conditions, especially thyroid problems. This is one reason why regular checkups with your doctor are important.
How to Treat Vitiligo
If you notice changes in your skin color, make an appointment with a dermatologist. They can confirm whether you have vitiligo and discuss treatment options that fit your symptoms, skin type, and overall health.
Many people ask, "How do you treat vitiligo?" There is no permanent cure, but several treatments can help restore color or slow the spread.
Treatment options may include:
- Topical medications: Corticosteroid creams or other prescription medications may help reduce inflammation and encourage repigmentation.
- Light therapy: Controlled ultraviolet light treatments can help some areas regain color over time.
- Depigmentation therapy: For widespread vitiligo, some people choose treatments that lighten the remaining skin tone to achieve a more even appearance.
- Surgery: Certain procedures, like skin grafting, may be an option for stable cases.
- Mental health support: Counseling or support groups can help people cope with the emotional effects of vitiligo.
It is also very important to protect your skin from the sun every day. Use sunscreen, wear protective clothing, and avoid prolonged exposure to direct sunlight to keep your skin safe.
