QUERCUS INFECTORIA GALL EXTRACT
Description
Quercus infectoria gall extract is a potent botanical ingredient derived from the oak tree species Quercus infectoria, native to Greece, Asia Minor, and Iran. This extract is obtained from galls, abnormal growths on the tree caused by parasitic wasps. Rich in tannins, particularly gallotannins, this extract exhibits strong astringent, antioxidant, and antimicrobial properties.
In skincare formulations, Quercus infectoria gall extract is prized for its ability to tighten and tone the skin, reduce excess sebum production, and minimize the appearance of enlarged pores. Its antimicrobial activity makes it effective against acne-causing bacteria, while its antioxidant properties help protect the skin from free radical damage and premature aging.
The extract's anti-inflammatory effects can soothe irritated skin and reduce redness, making it beneficial for sensitive and reactive skin types. It also demonstrates wound-healing properties, potentially aiding in the repair of damaged skin barriers. Typically used in concentrations between 0.1% to 1% in skincare products, Quercus infectoria gall extract is found in toners, serums, and spot treatments targeting oily, acne-prone, or aging skin concerns.
