Questionable CAS 8001-76-1 / SKIN CONDITIONING

A traditional Ayurvedic botanical extract rich in tannins and catechins that functions as a natural astringent and antioxidant. This bark powder demonstrates meaningful tyrosinase inhibition activity, achieving 61.58% enzyme suppression at 120 mg/ml concentrations. Its dual-action approach combines skin-tightening astringent properties with free radical neutralization for comprehensive skin conditioning.

Science

Functions through multiple pathways: high tannin content precipitates proteins and constricts skin tissues for astringent effects, while catechins neutralize free radicals and provide antioxidant protection. Inhibits tyrosinase enzyme activity to reduce melanin synthesis and blocks NF-kB inflammatory pathways to suppress pro-inflammatory cytokines like TNF-α.
