Natural cosmetic Ingredient
Siberian grace

Siberian larch extract, the main component of this pre-mix product, has very strong anti-oxidative effect.

Siberian larch is very rich in Dihydroquercetin (Taxifolin), which is one type of flavonoid polyphenol contributing to the strong anti-oxidative effect.

Dihydroquercetin itself is absolutely insoluble in water, but Siberian Grace is a premix ingredient that enables dihydroquercetin to be soluble in water.

Ethnobotany

In the old book, people native to the area of Anyui, Kolyma, and Verkhoyansk, inland of Eastern Russians used to drink the broth of the Siberian larch; they stripped off the bark, chopped it, and boiled it with water and milk.
