Why we use it

Ferment filtrates have been popular in Korea for many years as skincare ingredients. Fermentation helps break down ingredients into component parts that are easier for the skin to absorb and put to work. This particular ingredient comes from fermenting folic acid, better known as vitamin B9. The fermentation process makes the vitamin more stable as well as more bioavailable to the skin.
