KOSE Maihada Hadajun Cream

A rich moisturizing cream built around Rice Power No.11, the only ingredient in Japan officially approved to "improve the skin's moisture retention ability" (水分保持能の改善). That's a meaningful regulatory distinction: most moisturizers just sit on top, while Rice Power No.11 is clinically shown to help skin hold onto water on its own. The cream creates a protective emollient veil that locks in hydration while the active works underneath.

Part of KOSE's Maihada (米肌, literally "rice skin") line, which is the company's dedicated rice ferment skincare brand. Also contains bifidobacterium ferment extract and soy ferment extract for additional barrier support. Fragrance free, colorant free. Sold primarily through KOSE's own online shop and select retailers. Over 1,200 @cosme reviews. A solid choice for anyone serious about deep hydration, especially in dry winter months.
