Menopausal Symptoms

Effect for Beautiful Skin confirmed:
Moisture maintenance・collagen creation・suppressing action against melanin

As to the moisture maintenance, an application test on humans showed that the moisture loss of surface skin was improved by 15% against no application and the moisture content of the stratum corneum increased. Also, from the results of tracing changes of enzymes on OVX rats' skin and other researches, it was found that new production of collagen and hyaluronic acid was promoted.
In particular, it was confirmed that the proportion of young low cross-linked collagen increased. According to the experiment of the restraining effect on melanin cell formation using mouse cells, as the result of using a cosmetic plant extract containing 1% isoflavones, it was found that it has a strong restraining effect against melanin formation equal to arbutin as shown in the figure.
