Development Background and Features

There are many factors that lead to moisture concerns, such as weather, air conditioning/heating, and age. Countermeasures vary depending on the area of concern, and for those with concerns in multiple areas, it can be time-consuming and burdensome. It is also known that women of a wide range of ages experience moisture concerns in areas such as the eyes, mouth, and skin.

To shorten the care time and reduce the burden for such individuals, we have developed the "Foods with Function Claims" product "TSUYAHANA."

◆Easy Moisture Routine with Triple Support!

TSUYAHANA, through the action of eriodictyol-6-C-glucoside, simultaneously supports moisture in three areas: the eyes, mouth, and skin. This ingredient has been reported to maintain moisture in these three areas.
