skin conditioning antioxidant depigmenting anti-inflammatory antimicrobial

Science

Mechanism of Action

This extract functions as a potent antioxidant by effectively scavenging free radicals and demonstrating strong reducing power, primarily due to its high concentration of phenolic compounds, flavonoids, and tannins. Its promising depigmenting effect stems from its ability to inhibit tyrosinase activity, a key enzyme in melanin production, partly attributed to the presence of arbutin. Additionally, it exhibits moderate anti-inflammatory capabilities and possesses antimicrobial properties, contributing to skin balance.

Stability

Water is an effective solvent for extracting its active components. While arbutin, a key component, is light and pH stable, in aqueous matrices it can undergo hydrolysis and oxidation to transform into benzoquinone, a precursor to regulated hydroquinone, which requires careful consideration for long-term stability. The extract has been successfully formulated into oil-in-water nanoemulsions.
