What is Gallnut Extract?
Gallanut Extract (Galla Chinensis Extract) is a brown to tan extract or powder obtained from gallnuts through water extraction, alcohol extraction, or supercritical CO₂ extraction. Its active ingredients are gall tannins (also known as tannic acid), gallic acid, ellagic acid, and various trace elements (copper, zinc, iron, and calcium).

What are the benefits of gallnut extract for the skin?
Oil control and astringency
Tannins quickly bind to proteins on the skin's surface, forming a thin "protein film." Pores appear smaller and sebum release is less noticeable. Oily skin types will notice a noticeable improvement in their T-zone after two weeks of application.
Antibacterial and anti-inflammatory
In a laboratory, a paper strip containing gallnut extract was placed in a petri dish. After 24 hours, a nearly 2-centimeter "sterile zone" formed around Propionibacterium acnes. Red pimples on the face are actually a duet of bacteria and inflammation. Suppressing the bacteria will naturally reduce the redness and swelling.
Antioxidant and anti-darkness
Polyphenols are natural free radical killers. Apply two drops morning and night to gradually remove the yellowish tinge from late-night or computer-induced complexion, resulting in a brighter complexion.
Repairing the barrier
Gallnut extract gallic acid encourages the filaggrin and involucrin in the stratum corneum to work overtime, straightening the loose "brick wall." Trace elements zinc and copper act like masons, mixing the cement (lipids) more evenly. A thicker barrier reduces seasonal irritation and flaking.
Lightening spots
Ellagic acid blocks tyrosinase, preventing it from converting tyrosine into melanin. After a full metabolic cycle (28 days), the color of acne scars will visibly lighten.

Other Effects of Gallnut extract powder
Antibacterial and Antiviral
In addition to common skin bacteria, gallnut extract also exhibits inhibitory effects against Shigella dysenteriae, Salmonella typhi, Pseudomonas aeruginosa, and influenza virus PR8 strain. It can be used in prescriptions for diarrhea, dysentery, and upper respiratory tract infections.
Hemostasis and Antiulcer Effects
The protein coagulation effect of tannins can quickly form a protective film on wound surfaces, compressing capillaries to stop bleeding. After 30 seconds of endoscopic spraying, the compound gallnut solution achieved a 92.3% hemostasis rate for gastric ulcer bleeding.
Liver Protection and Detoxification
Animal studies have shown that gallnut tannic acid can inhibit CCl₄-induced acute liver damage and reduce ALT and AST levels. Its ability to complex heavy metal ions and alkaloids also makes it a natural "chemical detoxifier."
Anti-cancer and Anti-mutagenic Effects
In vitro studies have shown that gallnut hot water extract has an inhibition rate of over 90% against human cervical cancer JTC-26. Gallic acid can also block nitrosamine-induced lung adenoma formation in mice.
Daily Chemicals and Industry
High-purity tannic acid can be used in toothpaste for astringency and hemostasis, leather tanning, ink dyeing, boiler descaling, and beer clarification, making it a versatile agent across the pharmaceutical and daily chemical sectors.
