What's Sake Kasu?
Japan's Best-Kept Secret
Since 794 AD, Japanese court women used rice water for luminous skin. Sake brewers became known throughout Japan for their inexplicably youthful hands; a direct result of working daily in fermenting rice.
The secret was Sake Kasu: the fermented rice lees left after brewing, concentrated with over 300 Koji-unlocked bioactives. INÉ is the first to bring it to the world.
Kojic Magic
Sake Kasu is the fermented rice pulp leftover from Sake production.
Specifically, the Koji fermentation process breaks down rice starch into over 300 bioactive compounds, including Kojic Acid, α-Ethyl Glucoside, and Ferulic Acid.
These compounds work synergistically on barrier repair, melanin regulation, and collagen stimulation.
This is the biochemistry behind centuries of documented results.
The Hidden Gem from Sake Breweries
Skincare lovers will be excited to discover the diverse range of skin-loving actives and enzymes in Sake Kasu, including Kojic Acid, Ferulic Acid, Galactomyces, collagen-boosting a-EG, other amino acids, peptides, probiotics, antioxidants, and more!

From Ancient Beauty Secret to Modern Skincare Marvel
The Enduring Legacy of Rice in Beauty
The beauty benefits of rice have been known since 794 AD: Japanese court women of the Heian period used rice water to boost hair shine and strength. People took Sake-filled baths to nourish skin. And the inexplicably youthful and dewy hands of Sake brewers became Japanese lore.
In the 1970s, Japanese scientists finally conducted a formal research and uncovered the multitude of compounds in Sake that provide diverse skin benefits.
Today Sake is a well-loved skincare ingredient, yet the real treasure is Sake Kasu – a secret still only known to Japan.
