Komenuka Bijin, the Japanese brand of rice bran beauty products, has created several new products utilizing rice bran as well as sake yeast, both by-products of the sake brewing process. Sake yeast offers extraordinary moisturizing ability, and like rice bran, absorbs through the skin immediately so nothing is wasted and no residue is left on the surface. The Special Serum Toner is a toner and moisturizer, balancing the skin s appearance while softening. The concentration of rice extracts and sake yeast are high, so you should use small amounts at a time.
