Claims5
A method of promoting biosynthesis of collagen and improving at least one of skin wrinkle and elasticity comprising externally applying on the skin of a subject in need thereof a composition comprising a mixture of a catechin and theanine as active ingredients,
- wherein the content of the catechin in the composition is 0.0004 wt % to 0.025 wt % with regard to the total weight of the composition,
- wherein the content of the theanine in the composition is 0.01 wt % to 2.5 wt % with regard to the total weight of the composition,
- wherein a mixed weight ratio of the catechin to the theanine is 1:25˜1:100, and wherein the catechin is at least one selected from the group consisting of (−)GCG (gallocatechin gallate), (−)ECG (epicatechin gallate), and (−)CG (catechin gallate).
