Antioxidant Anti-inflammatory Astringent Skin Conditioning Wound Healing Anti-aging Skin Brightening Antimicrobial Hair Conditioning

Science

Mechanism of Action

This extract's efficacy is primarily attributed to its high concentration of polyphenols, including gallic and ellagic acids and ellagitannins. These compounds actively neutralize free radicals and diminish reactive oxygen species (ROS) accumulation, providing robust antioxidant protection. Its anti-inflammatory capabilities are evidenced by the suppression of nitric oxide production and iNOS expression. Additionally, it exhibits antimicrobial properties against specific pathogens, acts as an astringent to constrict pores and regulate sebum, and conditions the skin by forming a protective film. Potential benefits extend to skin brightening via tyrosinase inhibition and anti-aging effects through the prevention of collagen and elastase degradation, alongside promoting wound healing by enhancing angiogenesis and collagen synthesis.
