Catechin liposome freeze drying material and preparation method thereof

A catechin liposome freeze drying material contains liposome and hyaluronic acid. The liposome comprises a lecithin shell body having a containing space as well as catechin and glycosyl trehalose placed inside the containing space. The catechin liposome freeze drying material, in the synergistic effect of the ingredients, is refreshing and is easy to be absorbed by the skin, and also has the effect of preventing skin from aging. Moreover, through the use of hyaluronic acid as a lyoprotectant, it can effectively reduce the water in the catechin liposome freeze drying material, and in the freeze drying process, it can avoid destruction of the structure of catechin liposome freeze drying material, which leads to the problem of oxidation by the contact of catechin with the environment.
