Skin aging is the most common aging phenomenon of human body, and is mainly divided into natural aging and environmental aging, wherein the natural aging is mainly caused by internal factors of the body and is represented by wrinkles and skin laxity; environmental aging is mainly caused by light factors and is manifested by loose skin, deepened and thickened wrinkles, large pores and the like. With age, facial skin gradually ages, and eye skin becomes more problematic. In order to delay skin aging around eyes, in addition to ensuring sufficient sleep and developing good living habits and eye habits in daily life, the common method is to use anti-wrinkle moisturizing eye cosmetics. With the continuous research on wrinkle formation, the anti-wrinkle cosmetics are further developed, but most of the existing anti-wrinkle cosmetics are processed by preparing raw materials in a heating, stirring and homogenizing fusion mode according to a proper proportion, so that the interface effect among the raw materials cannot be broken, the quality of finished products is uneven, even precipitates are easily formed, and the anti-wrinkle effect is not obvious enough. If the application number is: cn201410224642.x discloses an eye cream containing fucoidin and pomegranate extract and a preparation method thereof.
