Amazake is a traditional Japanese sweet fermented rice drink, typically made by fermenting cooked rice with koji for a short period. Unlike sake, amazake contains little or no alcohol and has been a household staple — especially as a winter warm drink — for centuries. In cosmetics, amazake extract connects skincare to this familiar fermentation heritage.

What it is

Amazake is produced by fermenting cooked rice with koji (Aspergillus oryzae-inoculated rice) for 8 to 12 hours. The enzymatic action of koji breaks down rice starches into glucose, producing natural sweetness without added sugar, and amino acids from rice protein.

Cosmetic amazake extract is produced by water or hydro-alcoholic extraction of amazake, standardized for cosmetic use. The resulting ingredient concentrates the fermentation-derived amino acids and saccharides.

Typical uses in Japanese products

As food, amazake is a year-round beverage in contemporary Japan but retains strong winter and seasonal-festival associations. Sakura-season and winter product releases frequently feature amazake.

In cosmetics, amazake extract appears in essences, toners, and sheet masks in fermentation-positioned product lines.
