The fenugreek seed coat extract used in the present invention includes an extract obtained by using an extraction device, an extract, and an extract obtained after performing other treatments.

The blending amount of the fenugreek seed coat extract is not particularly limited as long as the desired desired effect can be obtained, and may include the form of the composition, the method of use, and the solid content of the extract. Can be set as appropriate, but 0.001 to 100% by weight, further 0.01 to 70% by weight, especially
0.1 to 30% by weight is preferable from the viewpoint of effects and economy. Further, it is preferable that saponin having a steroid skeleton is contained. The saponin content is not particularly limited, but is generally 0.0001% or more, preferably 0.001% or more, based on the total amount of the final composition. When used for the purpose of improvement, the content is preferably 0.1% or more. Further, among the saponins having this steroid skeleton, it is most preferable to contain saponins derived from fenugreek seed coat.
