Vitiligo and understanding pigment loss

Vitiligo causes loss of pigment in areas of skin, commonly through an immune mediated process. It is not contagious. The pace of change and response to treatment differ between people and body sites.

Not every pale patch is vitiligo

Pale patches have several possible causes. A clinician examines their distribution and edges and may use a special lamp to clarify pigment loss. Vitiligo is not cancer, and a colour change does not mean the skin is unclean or that the person can pass a disease to others. [1]

Progression and tests

Vitiligo may remain limited or develop in new areas, and its course cannot be predicted precisely for an individual. It can be associated with other autoimmune conditions, including thyroid disease. Tests are selected from the history and examination. Report fatigue, weight change, constipation or other new symptoms. [1]

Options to restore pigment

Options include topical corticosteroids or calcineurin inhibitors and phototherapy when suitable. Ruxolitinib cream is a newer option for selected nonsegmental vitiligo, depending on age and local authorization. Surgery may be discussed for selected stable disease, while rapidly active vitiligo may need a different approach. [2]

Time and expectations

Repigmentation takes time and is often assessed over months. Areas such as the face respond differently from fingertips, and success at one site does not guarantee the same response elsewhere. Camouflage and psychological support can be considered alongside treatment, rather than only after treatment is stopped. [2]

Sun protection and depigmentation

Protect depigmented skin with clothing, shade and suitable sunscreen, and avoid burns. Removing the remaining pigment is a separate, uncommon option for selected extensive cases and can have permanent consequences. Do not experiment with depigmenting creams or skin-lightening mixtures on your own. [2][3]

Key point

Care begins with confirming the diagnosis and setting a realistic goal. Skin protection and quality of life matter whether or not treatment is chosen. [1][2][3]
