Science
Mechanism of Action
This extract functions primarily through its high concentration of tannins, gallic acid, and ellagic acid. It acts as a potent astringent by constricting skin tissues, which visibly minimizes pore appearance and contributes to a firmer skin texture. Its anti-sebum capabilities regulate and reduce excess oil production, making it ideal for oily and acne-prone skin types. The phenolic compounds provide robust antioxidant activity, effectively neutralizing free radicals and mitigating oxidative damage from environmental aggressors. Furthermore, it exhibits anti-inflammatory effects that soothe minor skin irritations and possesses antimicrobial properties, helping to protect against microbial proliferation, including the bacterium Propionibacterium acne. The extract also serves as a skin conditioning agent, supporting overall skin health, smoothness, and hydration, and contributes to the natural wound healing process.

Key findings
- 01 An ethanolic extract significantly accelerated wound closure by approximately 9.4 times in H2O2-treated L929 fibroblasts. It also mitigated H2O2-induced cytotoxicity in a dose-dependent manner, while reducing intracellular reactive oxygen species production and inflammation-related gene expression.

Safety Profile
Generally recognized as safe for topical cosmetic applications, with a recommendation for patch testing to ensure individual compatibility. Data regarding its topical use during pregnancy and breastfeeding are currently insufficient; therefore, consultation with a healthcare professional is advised. Oral safety data from a related species (Quercus brantii gall) at high doses are not directly transferable to topical Quercus infectoria.
