I'm using another Japanese product right now called SIZUKU, it is a face mask with natural pulp essence which is YUZU. They have many other essence on the market.
Unfortunately lack of information in any other language than Japanese. But I do find some Japanese online shops and here's the details:
Love Labo’s Sizuku Face Mask Yuzu is a drugstore Japanese sheet mask featuring yuzu fruit to exfoliate away dead skin cells for brighten dull, lack-luster skin.
Relaxing Citron Scent
Ingredient List: Water,, butylene glycol,, glycerin,,citrus junos fruit extract,, sodium hyaluronate,, soluble collagen,, chlorella vulgaris extract,, pueraria lobata root extract,, dipotassium glycyrrhizate,, PEG-20 sorbitan cocoate,, disodium EDTA,, hydroxyethylcellulose,, methylparaben,, fragrance.
The citrus scent is mild and I really like the thinness of the mask which using it almost like transparent. Perfect for cooling in a hot or humid day and help exfoliating much simpler and a relaxing experience too.
The leftover liquid in the packaging is a waste if you throw it away, use it on your body ^__^
Sold in Japan for 105 Yen.
