Sake lees or sake kasu is a byproduct from the Japanese sake making process. Different from the rice wine itself, sake lees is the leftover material that is packed with protein, fiber, and vitamins but usually gets less attention than its liquid counterpart.
Skincare benefits of sake lees
Brightening
The Vitamin E, arbutin, and ferulic acid content found in sake kasu together work to combat hyperpigmentation and prevent the formation of age spots, sun spots, and skin inflammation, which makes sake lees one of the popular ingredients for Japanese brightening products.
Softening and soothing
Sake lees is the friend of sensitive skin, and it is known for its ability to help soothe skin conditions like eczema and acne.
Rejuvenating
Sake lees is well-known for its powerful anti-aging benefits. Its high Vitamin B content is said to help accelerate skin cell turnover, rejuvenating the skin and slowing down premature aging. Antioxidant ferulic acid also helps to protect the skin from the damaging effects of free radicals, minimize the formation of fine lines and enhance the skin’s firmness.
Moisturizing
Much like hyaluronic acid, the sugar compounds found in fermented rice act as emollients that
increase skin cell water retention for plump and elastic skin. Linoleic acid also helps to fortify the skin barrier so that it can hold on to moisture and defend the skin from outside irritants.
