All about Sake Lees: Japan’s Anti-ageing Superfood 

The star ingredient of EDOBIO’s products, Sake Lees (or 酒粕/sake kasu) is a by-product of the sake-making process. Rich in peptides, amino-acids and vitamins, it’s a Japanese beauty secret that’s been passed down from one generation to the next, and the Western beauty world is only just discovering it.

What differentiates sake lees from sake, and how does it benefit our skin? Read on to find out.


What is Sake Lees & how is it made?

Synonymous with Japan, sake is known worldwide for its unique flavour. A time-honoured tradition, the sake-making process usually involves inoculating steamed rice with a fungus called koji. The koji releases enzymes that break down rice starch into sugar, and when yeast is added, the sugars are converted into alcohol. After 27 days of fermentation, the fermented rice mash is pressed and the sake is drawn off. The solid mash that remains after the sake has been drawn off is what's known as sake kasu or sake lees.


Is Sake Lees eco-friendly?

As a by-product of the sake-making process, the Japanese have multiple uses for sake lees. Commonly recycled into amazake (sweet sake), sake lees can even be grilled and eaten like a cracker to or be incorporated by home cooks into dishes like bread, cheesecake or ice-cream.

However, most sake lees in Japan are actually disposed of as industrial waste and not repurposed at all. By using sake lee in cosmetics, beauty brands like EDOBIO contribute to ecology and embody clean beauty.


How does Sake Lees benefit the skin?

Sake lees’ claim to fame is it’s powerful anti-ageing benefits. Rich in Vitamin B, sake lees helps to speed up skin turnover and regenerate the skin, slowing down the ageing process and keeping the skin plump and firm. It is also rich in:

Arbutin
Aids in fading and lightening pigmentation and age spots

Linoleic Acid

Tried and tested by generations of Japanese women, sake lees has been proven to be effective in moisturizing and nourishing the skin, tightening pores and soothing inflammation and acne.
