Why is sunscreen important for people with vitiligo?

Using sunscreen is a fundamental pillar of the daily skincare routine for people with vitiligo, as the patches affected by white spots lack melanin, the natural pigment that provides self-protection for the skin against harmful ultraviolet radiation [3]. This means that the skin in these areas is more susceptible to the risk of sun damage and sunburn compared to healthy skin. Beyond physical protection, sunscreen plays an important cosmetic role; it prevents the surrounding healthy skin from tanning further as a result of sun exposure, which helps reduce the color contrast between the affected areas and normal skin, making the spots less noticeable [3].

Why is skin affected by vitiligo more sensitive to the sun?

Vitiligo is an autoimmune disorder in which the immune system attacks and destroys melanocytes, the cells responsible for producing skin pigment [2]. When these cells are destroyed, the skin loses its ability to protect itself from sunlight, leading to the appearance of milky white patches. The danger of this condition is increased because areas with reduced pigmentation, such as the face, hands, and knees, are naturally and continuously exposed to solar radiation, which raises the likelihood of cumulative skin damage if appropriate preventive measures are not taken [3].

How to choose sunscreen and the options available

When selecting the appropriate product, experts recommend using a broad-spectrum sunscreen that offers dual protection against UVA and UVB rays, choosing a high sun protection factor (SPF) to ensure maximum protection for sensitive areas [3]. You must ensure the product is applied evenly to all exposed areas of the skin. It is not limited to sunscreen alone; vitiligo patients should use additional protection methods, such as wearing protective clothing that covers the skin, including long-sleeved shirts and pants, as well as wide-brimmed hats, especially when outdoors for long periods [3].

Psychological management and preventing color contrast

The visible skin changes resulting from vitiligo directly affect self-confidence and quality of life [2]. Using sunscreen is not just a preventive measure, but a tool that helps manage the aesthetic appearance of the skin by limiting the tanning of normal skin, which makes white patches less contrasting and visible to the eye.

When should you see a doctor?

While vitiligo is a chronic condition, it requires periodic medical follow-up. If you notice the appearance of new depigmented patches without a previous skin injury, or if you are having difficulty caring for the affected skin, it is essential to consult a dermatologist to evaluate the condition [3]. The doctor may suggest additional tests to ensure there are no other immune disorders associated with vitiligo, such as thyroid problems or type 1 diabetes, and provide a personalized treatment plan that includes options like phototherapy or modern topical creams [3].
