The kojic acids in rice wine (sake) decrease your skin’s ability to form the type of melanin found in age spots and freckles. If you put sake on your face or use skincare products containing sake or kojic acid, you’ll also find the rice wine keeps moisture in your skin.

There’s a decade-old book on the market published by Jeanette Jacknin MD, a dermatologist. It’s title is Smart Medicine for Your Skin (Penguin Putnam, 2001) which explains the skin-benefits of wine on your face.

Kojic acid, is a by-product of the fermentation process of Japanese sake. It shows some improvement in fading dark pigmented spots on the skin because it inhibits tyrosinase. However, the ingredient is known for its instability in cosmetic formulas.

You can buy pure kojic acid online (from the Phillipines) at Sulit.com.Ph or use sake. Make your own rice wine if you want to work from scratch with natural products. Kojic acid derived from a mushroom also is found in Sake (Japanese rice wine) that you can buy in the USA and in many other countries.
