Pero, \u00bfsu f\u00f3rmula realmente funciona o solo se est\u00e1 volviendo marr\u00f3n en el estante?<\/p><p>Abordemos el elefante en el laboratorio de I+D. Los consumidores reconocen el Resveratrol. Los especialistas en marketing lo venden f\u00e1cilmente. Pero los formuladores lo odian en secreto. El Resveratrol est\u00e1ndar odia la luz. Odia el ox\u00edgeno. Como fabricante de ingredientes activos cosm\u00e9ticos, observamos a las marcas luchar diariamente con este exacto problema de estabilidad.<\/p><p>Deje de luchar contra la qu\u00edmica. Si desea un brillo de piel a nivel cl\u00ednico sin las pesadillas de estabilidad, debe considerar el Pterostilbeno.<\/p><p>Observe la estructura molecular. El Pterostilbeno es simplemente Resveratrol con un impermeable lip\u00eddico. Cambiamos dos grupos hidroxilo por grupos metoxi. Este peque\u00f1o cambio estructural cambia por completo el comportamiento de la mol\u00e9cula. Penetra inmediatamente en la barrera cut\u00e1nea rica en l\u00edpidos. \u00bfDesea un activo caro que se quede muerto en la superficie de la piel o uno que penetre activamente hasta la capa basal para detener la producci\u00f3n de melanina?<\/p><p>Los datos nunca mienten<\/p><p>Veamos los n\u00fameros brutos.

Quer\u00edan un s\u00e9rum de brillo premium. Su prototipo inicial se basaba en Resveratrol 1%. Se ve\u00eda impecable el primer d\u00eda. A los 45 d\u00edas en la incubadora de estabilidad a 40 \u00b0C, el s\u00e9rum se oxid\u00f3 hasta convertirse en un l\u00edquido amarillo turbio. Las pruebas de eficacia mostraron que la degradaci\u00f3n molecular activa alcanz\u00f3 el 60%.<\/p><p>Les dijimos que hicieran un cambio radical. Eliminar por completo el Resveratrol. A\u00f1adir 0.5% de Pterostilbeno. S\u00ed, exactamente la mitad de la dosis.<\/p><p>\u00bfEl resultado? El s\u00e9rum se mantuvo cristalino durante 90 d\u00edas completos. Realizamos una prueba est\u00e1ndar de c\u00e9lula de difusi\u00f3n Franz en modelos de epidermis humana. Los grupos metoxi estructurales permiten que el Pterostilbeno atraviese el estrato c\u00f3rneo de manera muy eficiente.<\/p><figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Tiempo (Horas)<\/strong><\/td><td><strong>Retenci\u00f3n de Resveratrol en la Epidermis<\/strong><\/td><td><strong>Retenci\u00f3n de Pterostilbeno en la Epidermis<\/strong><\/td><\/tr><\/thead><tbody><tr><td>2 Horas<\/td><td>1.2%<\/td><td>4.5%<\/td><\/tr><tr><td>6 Horas<\/td><td>3.5%<\/td><td>11.2%<\/td><\/tr><tr><td>12 Horas<\/td><td>5.8%<\/td><td>18.6%<\/td><\/tr><\/tbody><\/table><\/figure><p>Consejos de formulaci\u00f3n desde la f\u00e1brica<\/p><p>No vierta estos polvos en su fase acuosa.
