Melasma - Overview

Nombres alternativos

Cloasma; Máscara del embarazo

Definición:

Es una coloración oscura de la piel que aparece en áreas de la cara expuestas al sol.

Causas, incidencia y factores de riesgo:

El melasma es un trastorno cutáneo muy común y, aunque puede afectar a cualquier persona, las mujeres jóvenes con tonos de piel canela son quienes están en mayor riesgo.

El melasma se asocia a menudo con las hormonas femeninas estrógenos y progesterona. Es especialmente común en mujeres embarazadas, entre aquellas que están tomando pastillas anticonceptivas (anticonceptivos orales) y entre las que toman hormonoterapia durante la menopausia.

La exposición al sol también es un factor de riesgo fuerte para desarrollar melasma, una afección particularmente común en los climas tropicales.
