INCI: Quercus infectoria gall extract/ Quercus infectoria fruit extract.

What is Quercus infectoria extract?

Quercus infectoria extract is obtained from a plant called Quercus infectoria. It is an oak tree commonly called Aleppo oak. It is widely grown in Southern Europe, Middle East, and South to Southwestern Asia. It has been used traditionally as medicine for ages in many parts of Asia. The extract obtained from galls and fruit is rich in tannins, gallic, and ellagic acid. It is used to treat many ailments in addition to its use in cosmetic products.

Use & Benefits:

Quercus infectoria extracts are mainly used for their antioxidant, astringent, antimicrobial, and skin conditioning properties in a wide variety of cosmetic products. Tannins, gallic and ellagic acid are natural compounds that act as antioxidants. When our skin gets exposed to harmful radiation, chemicals, or allergens present in the atmosphere, it produces free radicals. These free radicals damage skin in various ways making it dull, lifeless. Antioxidant scavenges skin from the free radicals and reverses the damage caused. As an astringent, it reacts with dead skin cells, loosens them from the base layer, and helps get rid of them. Also, it constricts the pores of the skin and reduces excess oil appearing on the skin. It makes the skin look one shade lighter and even-toned. Its anti-microbial property protects the product and skin from microbial infections. It forms a protective film on the surface of the skin and makes it appears smooth and soft. It prevents loss of moisture from the skin and lubricates it. It is used in formulations of body care, baby care, bath products, and other skincare products.
