Vitiligo: can self-tanner conceal depigmented areas?

The vitiligo is a skin disorder characterised by a localised depigmentation due to melanocyte loss, the cells responsible for melanin production. This absence of pigment appears as lighter patches of skin, which can extend over large areas of the body. Although the vitiligo is not harmful in itself, though it can be challenging to live with.

To conceal depigmented areas, some people use a self-tanner. These formulas include dihydroxyacétone, a molecule that reacts with the amino acids in the stratum corneum, the outermost skin layer, to form melanoidins, pigments distinct from melanin yet also imparting a brown hue to the skin. The self-tanners are convenient for mimicking a natural tan without sun exposure. The colour appears a few hours after application and can last between three and seven days, depending on the product and skin type.

Self-tanning, thanks to the temporary pigmentation it provides, offers a non-invasive topical solution to reduce the contrast between depigmented areas and the surrounding skin in people with vitiligo.

By applying a suitable self tan product regularly, it becomes possible to achieve a uniform tone that mimics pigmented skin. This method offers several benefits, including its ability to suit various skin tones by selecting the right shade. Moreover, the self tan products are available at affordable prices and do not require medical consultation.

While practical in theory, self-tanner is only a temporary solution that does not treat depigmentation. It requires regular reapplication to maintain an optimal result. Its use may be impractical for people with vitiligo when depigmented areas are numerous or poorly defined, making even application more difficult. Some light areas may also respond unevenly, which can emphasise contrasts rather than reduce them. Finally, it is essential to note that self-tanner does not protect against UV rays, so appropriate sun protection is necessary to preserve depigmented skin.
