The HOBO bathing face mask is a sheet mask that contains 83% Hokkaido's Noboribetsu Karlus hot spring water, developed for use in a bathing environment. It was born after hearing from many customers at the site of a hot spring inn that their skin dries out after taking a bath. At the time of its release in July 2023, it was the first non-woven sheet mask for bathing in Japan. While sweating while bathing, the skin is prone to loss of moisture, and many people feel tight and dry after bathing. This product is designed to turn bathing time into skin care time, delivering the moisture of Karlus hot spring water to the skin and leading to a moist condition. The glycerin-free and oil-free formula is easy to use even for those who don't like stickiness, and the sheet is both gentle and adherent. In addition, it is designed to be used in large public baths and bathrooms, and is designed to prevent dirt and slippage even if liquid gets on the floor. This piece is recommended not only for special care at home, but also for amenity proposals at hot bath facilities and accommodation facilities, as well as for gift demand.
