Each year, the World Vitiligo Day invites us to focus on a condition that affects millions of people worldwide and that is still often misunderstood. It is frequently reduced to an aesthetic issue, when in fact it is an autoimmune disease that can have a strong emotional and social impact.
What vitiligo is and who it affects
Vitiligo is a chronic autoimmune disease that causes progressive loss of pigmentation. It occurs when the immune system targets melanocytes, the cells responsible for producing melanin, the pigment that gives color to the skin, eyes, and hair. As a result, white patches appear on various parts of the body, especially in sun-exposed areas such as the face, hands, or elbows.
It can manifest at any age, though it is more common between ages 10 and 30. According to the American Academy of Dermatology and the World Health Organization, it affects between 0.5% and 2% of the global population, representing more than 70 million people worldwide.
“Vitiligo is a disease, not a matter of aesthetics. Naming it correctly is not a mere technicality, because that perspective determines the early diagnosis, access to treatment, and how we support each patient”, says Dr. Leisa Molinari, a dermatologist specializing in skin cancer and Mohs micrographic surgery.
The impact that is often unseen
Beyond the spots, vitiligo can carry a profound emotional impact. The visibility of the lesions can lead to comments, biases, and isolation, especially during childhood and adolescence.
People living with this condition may also experience anxiety, low self-esteem, and difficulties in forming connections. In a context where social media and filters often reinforce ideals of perfection, that pressure can intensify. Therefore, downplaying vitiligo means ignoring everything the disease mobilizes in the daily lives of those who have it.
Why it appears
So far, no single cause is known. Vitiligo is thought to arise from a combination of genetic, immunological, and environmental factors.
In some cases there are familial antecedentes, and moreover, severe stress or physical trauma can act as triggers.
What treatments exist today
Although there is no definitive cure, there are currently treatments that help halt the progression of the disease and stimulate skin repigmentation.
Among therapeutic options are topical creams containing corticosteroids or immunomodulators, melanocyte transplantation, micropigmentation, and narrow-band UVB phototherapy. This latter treatment can be enhanced with Polypodium leucotomos, a plant-derived component with antioxidant and anti-inflammatory properties that neutralizes free radicals and, when combined with phototherapy, accelerates repigmentation, especially on the face and neck.
The choice of treatment depends on the patient, the extent of the patches, and the duration of the disease. Therefore, early consultation is key to having more therapeutic tools and achieving better outcomes.
A holistic view of care
“For many years I have viewed dermatology as a preventive and holistic discipline: caring for the skin means addressing what is visible and also supporting what the person feels. In vitiligo, this perspective matters especially, because medical treatment progresses alongside something equally necessary, which is emotional support and the creation of environments that do not discriminate. As important as treating the patch is caring for the person who has it,” concludes Dr. Molinari.
In that sense, World Vitiligo Day aims to raise visibility of the condition, promote early diagnosis, drive research, and facilitate access to effective treatments. But it also invites reflection on the importance of empathy, inclusion, and acceptance. Because vitiligo does not physically limit someone, although it can affect them emotionally, and the visible marks on the skin should not define anyone.
