Sake lees can remove blemishes on the face! How to make homemade Koji lotion

Sake lees is good for 'blemishes'?

Thank you for your continued support. We are "Hacco to go!", a shop specialising in sake lees and fermentation.

I am a member of FARM8, which runs a shop specialising in sake-kasu and fermentation in Niigata Station called 'Hacco to go!' and an online shop for products using sake-kasu and fermentation, as well as a daily blog to tell the fascinating story of sake-kasu.

As we work with such sake lees, we frequently visit the brewery. Talking with the brewers, we noticed that the toji's hands are white and clean.

When we wondered and investigated, we found that the power of koji mold is involved. It seems that an ingredient called 'kojic acid' possessed by koji mold has a skin-whitening effect. Kojic acid is an ingredient discovered in koji mould. In other words, the same ingredient is contained in 'sake-kasu' (sake lees), which is made from koji mould.

Sake lees is a by-product of sake production. It is full of ingredients that are good for beauty and health.


Sake lees is a notable skin-brightening ingredient.

That is not the only skin-brightening effect of sake lees. It also contains other whitening ingredients that are even more remarkable. We will explain them one by one, including the effects of kojic acid.

[Kojic acid].

It suppresses the production of melanin, which is the cause of spots and freckles. It is also said to be effective against spots that have been formed for a long time. It also reduces the causes of skin ageing, such as wrinkles and sagging.


Derivative of hydroquinone, which has a high whitening effect. Acts to prevent the build-up of melanin pigments formed when exposed to UV radiation.

[Ferulic acid].

Has antioxidant properties and reduces melanin production. It has a UV-absorbing effect, so when applied to the skin, ferulic acid can stop UV rays.


Ceramides are essential components of our skin. One of these is sphingolipids, which help to improve skin texture and retain moisture.

[Amino acids].

Amino acids that improve skin metabolism. Sake lees are rich in amino acids and peptides, which are the building blocks of protein. Nine of these essential amino acids (*) have a very good amino acid composition. In other words, sake lees is an excellent food supplement for body protein.

*Essential amino acids: amino acids that cannot be synthesised in the body and must therefore be supplied by food.

[Nucleic acid].

Nucleic acids are necessary for the renewal of new cells. Not only that, they also play an important role when B vitamins work in the body.

All this suggests that sake lees is powerfully effective in preventing blemishes and promoting whitening.

Try making your own whitening serum using sake lees.

Daily use of a whitening serum containing vitamin C derivatives, an ingredient that fades spots, and tranexamic acid, a preventive whitening ingredient, would certainly be effective.

But, however, such whitening serums are expensive ....... Even if you want to use them all over your body, you may not be able to use them in batches.

So I thought, "Wouldn't it be the most powerful if I could make a lotion with sake lees?" So we made an experimental version.

It made a lot more than I thought it would! I can use this all over my body without hesitation. You could put it on your shoulders and arms that have been over-exposed to the sun, or even on the top of your head where you burn the most...! It would also be good to put it in a bath and use it as a sake lees bath.

I keep it in the fridge and use it, it feels nice and cool. And I use it sparingly every morning and evening.

I actually started to feel some changes after about the second week of use, I'd like to continue for two months and see what happens.
