Vitiligo: Causes, Misconceptions, Patient Impact, and Teva’s Innovation

A scientific and patient-centered overview of vitiligo, covering what it is, what causes it, how it affects people’s lives, common misconceptions, and Teva’s work to advance innovation in care.

Vitiligo is a chronic autoimmune disease that causes patches of skin to lose pigment or color. With the aim of promoting a better understanding of the condition beyond its visible symptoms, we look at the science behind vitiligo as a chronic autoimmune disease. We also explore its emotional and social impact through patient perspectives, addressing common misconceptions that contribute to stigma and under-recognition.

The burden of vitiligo has historically been under-recognized as it used to be mischaracterized as a cosmetic issue rather than an autoimmune disease 01 . Beyond visible skin changes, vitiligo can affect emotional wellbeing, and studies report a substantial quality-of-life burden associated with the condition, particularly when misconceptions lead others to dismiss its impact 02.

There is no known cure for vitiligo 03, but emerging research – including Teva’s investigational therapies – are advancing understanding of the immune pathways involved in the disease.

Summary of key article takeaways

• Vitiligo is a chronic autoimmune disease in which cells that produce melanin (melanocytes) are destroyed, causing of skin to lose pigment.
• Vitiligo affects millions of people worldwide and can have a substantial emotional and social impact.
• Misconceptions that vitiligo is merely cosmetic can contribute to under-recognition and stigma.
• Patient perspectives show that vitiligo can affect confidence, relationships, and daily life.
• Teva is advancing investigational research in vitiligo aimed at immune pathways involved in disease activity.

What is vitiligo?

Vitiligo is a chronic, progressive autoimmune disease, in which the immune system targets and destroys the cells that produce melanin (melanocytes). This causes depigmented lesions to appear on the patient’s skin. The resulting loss of pigment can appear on different parts of the body and may progress over time 04.

Is there a cure for vitiligo?

There is no known cure for vitiligo. However, available approaches such as topical therapies and photo-therapy may help some people manage the condition, and research continues to explore additional treatment options that directly affect the melanocyte destruction process 03.

How can the condition affect daily life?

For many patients, vitiligo on the face and hands is particularly burdensome because it is difficult to hide and can affect how they feel in social, professional, and personal settings. It can influence confidence, willingness to engage socially, and the constant decisions around whether to explain, cover, or avoid attention.

Studies report a substantial quality-of-life burden associated with the condition, particularly when misconceptions lead others to dismiss its impact 02.

What do patient perspectives and emerging science tell us about vitiligo?

Since January 2025, Teva has gathered insights from patients diagnosed with vitiligo to share their personal experiences and perspectives. Many people with vitiligo describe a hidden “mental load”—planning, explaining, or deciding whether to cover lesions—especially in new social or work situations. Vitiligo is not defined only by visible patches, but by the constant, daily decisions that come with them. What to wear. Where to sit. Whether to explain—or stay silent. The responses highlight the human impact of the condition and the need for better understanding and treatment options.

“People always thought I was a burn victim. I’ve had to explain it my whole life.”
- Male respondent

“People have comments. I was very self-conscious in dating and all that early on, but thankfully I found someone that looked past it.”
- Female respondent

“Vitiligo makes me feel like my body isn't whole. It's what I describe as a body dysmorphia kind of thing. My body doesn't look normal to me, even though other people may think that it looks normal. I feel super social anxiety when meeting new people.”
- Female respondent

“Meaningful improvement is being able to look in the mirror and not have it be the first thing I notice.”
- Female respondent

These perspectives align with published research showing that vitiligo can place a substantial burden on quality of life 02.

Given the prevalence of vitiligo and its psychosocial impact, there is a clear need to deepen understanding of the underlying science and continue developing improved treatment approaches.

How is Teva advancing innovation in vitiligo care?

At Teva, advancing our understanding of disease means going beyond clinical definitions and engaging with the full patient experience. Insights like the above, grounded in patient voices, inform how we think about innovation, medical research, and care. We are pursuing investigational research in vitiligo with the aim of addressing immune pathways involved in disease activity and supporting progress toward new treatment options for people living with this chronic autoimmune condition. The disease remains an area of significant unmet need, with limited treatment options and no approved systemic therapies 03.
