Abstract

Provided are a composition including coumestrol extracted from soybeans as an active ingredient, and a method of inhibiting cortisone reductase by applying it to skin of a subject.

Claims (6)

1 . A method of improving skin barrier function that has been compromised by an increase in the cortisol level within the epidermis in a subject, comprising applying an effective amount of a composition to skin of the subject,

wherein the composition comprises coumestrol extracted from soybeans as an active ingredient in a concentration range of 0.001 μM to 10 μM,

wherein the increase in cortisol level within the epidermis is caused by mental stress,

wherein the increase in cortisol level within the epidermis caused by mental stress is simulated by UV irradiation and the addition of cortisone to human keratinocytes, and

wherein the composition is a cosmetic composition.

2 . The method of claim 1 , wherein the soybeans comprise beans selected from soybean peas and mung beans, germinated beans germinated from the beans, or a combination thereof.
