The present invention relates to a transparent or semitransparent cosmetic composition in which the stability of amentoflavone is enhanced, and more particularly, to a transparent or semitransparent cosmetic composition, wherein a water-soluble amentoflavone-oligomer complex, in which amentoflavone is encapsulated in a hollow structure of an oligomer structure, is stabilized in a second agent containing a polyhydric alcohol, a two-liquid-type container is used to mix first and second agents before use, and hydrotrope is contained in the first agent to increase the mixing stability of the first and second agents and thereby enhance the stability of amentoflavone.
