El vitíligo afecta a personas de todo tipo de piel, pero puede ser más notorio en personas con piel morena o negra. La afección no pone en peligro la vida ni es contagiosa.

En esta enfermedad existe la pérdida del color de la piel en parches. Las áreas descoloridas generalmente aumentan de tamaño con el tiempo. La condición puede afectar la piel en cualquier parte del cuerpo. También puede afectar el cabello y el interior de la boca.

Tiene influencia en el autoestima de las personas, una de las causas de consulta más frecuentes.

TRATAMIENTO DEL VITILIGO

El tratamiento para el vitíligo puede restaurar el color de la piel afectada. Pero no previene la pérdida continua del color de la piel o una recurrencia.

Consulte a su proveedor de atención médica si las áreas de su piel, cabello o membranas mucosas pierden coloración. El vitíligo no tiene cura. Pero el tratamiento podría detener o retardar el proceso de decoloración y devolverle algo de color a la piel.
