\"Identificar<\/p>\n

Las manchas en la piel asociadas a la <\/b>exposici\u00f3n solar<\/b><\/span> no responden todas al mismo patr\u00f3n: identificar si se trata de lentigos <\/b>o melasma <\/b>es clave para definir el tratamiento m\u00e1s adecuado y entender qu\u00e9 resultados pueden esperarse.<\/p>\n

Esa es una de las principales distinciones que plante\u00f3 Adri\u00e1n Alegre<\/b>, dermat\u00f3logo del Grupo Espa\u00f1ol de Dermatolog\u00eda Est\u00e9tica y Terap\u00e9utica (GEDET) y director de la Unidad de Dermatolog\u00eda de la Cl\u00ednica AB Derma, en una explicaci\u00f3n difundida por GQ<\/i> sobre las hiperpigmentaciones m\u00e1s frecuentes y su manejo<\/b>.<\/p>\n

C\u00f3mo distinguir lentigos y melasma<\/h2>\n

El primer paso para abordar una mancha solar consiste en reconocer sus caracter\u00edsticas<\/b>. Seg\u00fan Alegre, los lentigos solares suelen presentarse como marcas redondeadas, bien delimitadas y concentradas en puntos concretos de la piel<\/b>. En cambio, el melasma tiende a verse como una pigmentaci\u00f3n m\u00e1s extensa, sim\u00e9trica y difusa<\/b>, con presencia habitual en mejillas, frente y labio superior.<\/p>\n

La diferencia entre ambos cuadros no es solo visual<\/b>. Tambi\u00e9n determina la elecci\u00f3n del tratamiento y la expectativa cl\u00ednica. Mientras los lentigos suelen responder a una acumulaci\u00f3n localizada de pigmento, el melasma se vincula con un proceso m\u00e1s complejo y persistente, que exige seguimiento a largo plazo.<\/p>\n

Por qu\u00e9 aparecen las manchas<\/h2>\n

\"La<\/p>\n

La formaci\u00f3n de estas marcas est\u00e1 relacionada con la manera en que la piel se defiende de la radiaci\u00f3n ultravioleta<\/b>. Ante la exposici\u00f3n solar, unas c\u00e9lulas llamadas melanocitos <\/b>estimulan la producci\u00f3n de melanina<\/b>, el pigmento natural que da color a la piel, el pelo y los ojos.<\/p>\n

Cuando esa melanina no se distribuye de forma uniforme y se concentra en determinadas zonas, aparecen \u00e1reas m\u00e1s oscuras. Ese mecanismo explica por qu\u00e9 una misma exposici\u00f3n puede dejar como resultado un tono parejo en algunas personas y manchas visibles en otras. El proceso, adem\u00e1s, no depende de un \u00fanico factor.<\/p>\n

Alegre se\u00f1al\u00f3 que \u201cning\u00fan protector solar bloquea el 100 % de la radiaci\u00f3n\u201d<\/b> y precis\u00f3 que tambi\u00e9n influyen el calor, la luz visible y la predisposici\u00f3n gen\u00e9tica. En ese marco, la fotoprotecci\u00f3n reduce el riesgo de nuevas lesiones, pero no garantiza una prevenci\u00f3n absoluta.<\/p>\n

Qu\u00e9 hay detr\u00e1s del melasma<\/h2>\n

Durante a\u00f1os, el foco del tratamiento estuvo puesto casi exclusivamente en la melanina<\/b>. Sin embargo, el especialista explic\u00f3 que en el caso del melasma hoy se considera tambi\u00e9n el peso de otros mecanismos cut\u00e1neos. <\/p>\n

Seg\u00fan indic\u00f3, \u201cno depende solo de la melanina\u201d, <\/b>ya que presenta un componente de inflamaci\u00f3n d\u00e9rmica y alteraciones vasculares que participan en su desarrollo.<\/p>\n

\"El<\/p>\n

Ese dato modifica el enfoque terap\u00e9utico. Si la mancha no obedece \u00fanicamente a un exceso de pigmento, la respuesta no puede basarse en una sola herramienta. De ah\u00ed que el abordaje del melasma suela combinar distintas opciones y requiera controles peri\u00f3dicos para evitar reca\u00eddas.<\/p>\n

Qu\u00e9 tratamiento sirve para cada caso<\/h2>\n

El tratamiento m\u00e9dico cambia seg\u00fan el diagn\u00f3stico<\/b>. En los lentigos, Alegre indic\u00f3 que los l\u00e1seres pigmentarios<\/b>, en especial los de picosegundos, y la Luz Pulsada Intensa (IPL) <\/b>ofrecen buenos resultados. Se trata de tecnolog\u00edas dirigidas a pigmentaciones bien definidas, donde la respuesta suele ser m\u00e1s previsible.<\/p>\n

En el melasma, en cambio, el esquema suele incluir despigmentantes, peelings<\/b> y, en algunos casos, l\u00e1seres espec\u00edficos <\/b>seleccionados con cautela. El dermat\u00f3logo remarc\u00f3 que la clave est\u00e1 en adaptar la estrategia a una patolog\u00eda cr\u00f3nica, con tendencia a reaparecer<\/b>, y no en esperar una resoluci\u00f3n definitiva con una sola intervenci\u00f3n.<\/p>\n

Tambi\u00e9n importa el momento en que se inicia el tratamiento. El especialista advirti\u00f3 que \u201cen la mayor\u00eda de los casos, es conveniente esperar unas semanas despu\u00e9s de la \u00faltima exposici\u00f3n solar intensa\u201d<\/b> antes de empezar procedimientos en consultorio, sobre todo si la piel contin\u00faa bronceada o presenta inflamaci\u00f3n.<\/p>\n

No todas las manchas tienen el mismo pron\u00f3stico<\/h2>\n

\"Los<\/p>\n

Las expectativas deben ajustarse al tipo de lesi\u00f3n<\/b>. Seg\u00fan Alegre, los lentigos pueden eliminarse de forma definitiva, siempre que se indique el procedimiento adecuado. El pron\u00f3stico del melasma es distinto: puede controlarse de manera eficaz, aunque requiere cuidados constantes y mantenimiento sostenido.<\/p>\n

Ese seguimiento suele incluir protecci\u00f3n solar estricta, el uso de renovadores como el retinol, despigmentantes de indicaci\u00f3n m\u00e9dica y sesiones en consultorio con tecnolog\u00edas como l\u00e1seres o microagujas. El objetivo, en estos casos, es reducir la pigmentaci\u00f3n visible y limitar la reaparici\u00f3n de las manchas.<\/p>\n

La rutina en casa ayuda a prevenir reca\u00eddas y mejorar manchas superficiales<\/h2>\n

La prevenci\u00f3n ocupa un lugar central en cualquier estrategia contra la hiperpigmentaci\u00f3n<\/b>. El dermat\u00f3logo recomend\u00f3 usar fotoprotector de amplio espectro con SPF50<\/b> durante todo el a\u00f1o, ya que el da\u00f1o solar es acumulativo y puede originar alteraciones que se vuelven visibles con el tiempo.<\/p>\n

Para el cuidado diario, el especialista mencion\u00f3 activos como la vitamina C<\/b>, la niacinamida<\/b>, el \u00e1cido azelaico <\/b>y el \u00e1cido tranex\u00e1mico, <\/b>adem\u00e1s de retinoides<\/b> cuando est\u00e1n indicados. Esos compuestos pueden mejorar manchas superficiales y colaborar en la prevenci\u00f3n de reca\u00eddas.<\/p>\n

Aun as\u00ed, el manejo domiciliario tiene l\u00edmites. Alegre advirti\u00f3 que, cuando las manchas son persistentes, muy extensas o generan dudas diagn\u00f3sticas, conviene consultar al dermat\u00f3logo para valorar tratamientos m\u00e9dicos, profesionales y personalizados.<\/p>\n","protected":false},"excerpt":{"rendered":"
