This extra-thick sheet mask contains sake lees extract (a moisturizing ingredient) to leave skin feeling plump and clear. Sake lees are a by-product of sake brewing. It's long been said that the hands of brewers (sake artisans) who handle sake lees are beautiful, leading to the popularity of rinse-off sake lees beauty treatments. To make this sake lees beauty treatment even more accessible, we've created a sheet mask infused with sake lees extract. It contains our original sake lees extract, extracted from sake lees at Kawazu Sake Brewery in Kumamoto Prefecture. Domestically grown rice, primarily from Aso, is polished using Aso spring water and Kumamoto yeast (Association Yeast No. 9), and the sake lees are gently pressed using the traditional vat-pressing method. This extra-thick sheet mask is packed with serum, allowing it to penetrate deep into the stratum corneum. It also has a subtle sake scent. Recommended for those seeking clearer skin and those concerned about dullness and dryness. *The packaging and ingredients of this product may change without notice.
