The invention relates to a triad integration freckle-removing functional nano cream for skin external use and a method for preparing the same. The three types (night use type, daytime use type and auxiliary type) freckle-removing nano creams improve and optimize a novel international passive target transdermal drug delivery system (TDDS) as a carrier, and organically combine and solubilize freckle-removing functional components with different biological efficacies, action ways and physical and chemical properties to form a good mutual aid synergic function system which has remarkable effect of controlling and relieving colored patches (such as chloasma, inflammatory pigmentation, sunburn, and the like) caused by abnormal facial metabolism of pigment. The product has the advantages of tiny particle sizes of spherical particles, obvious passive target function, excellent adaptability, homodromous property, fluidity and dispersion, strong penetrability, even texture, subtleness, lubricity and luster, is simple and convenient to use, and is comfortable without pungency and side effects; besides, the appearance is light yellow with slight opalescence, is glittering and translucent, clear and transparent, sticky but not viscous, thick but not dense, and oily but not greasy, has good stability, excellent curative effect, short industrialization cycle and high production efficiency, saves time, materials and energy sources, dose not need special devices and heat energy, and is easy for popularization and application.
