Science
Mechanism of Action
This extract operates through a dual-action pathway: it inhibits tyrosinase activity to prevent melanin synthesis via its high arbutin concentration (15-20%) and downregulates pro-inflammatory cytokines like IL-6 and TNF-alpha. Furthermore, its rich polyphenol profile neutralizes peroxy radicals while high tannin levels provide a natural astringent effect.

Dusting Analysis
Because it is an expensive botanical, many brands include it at negligible levels (below 0.1%) for 'label claims.' Efficacy for immune stimulation and brightening begins at approximately 0.3% concentrations.
The Formula
Formulation
Stability
Maintains peak stability in slightly acidic, water-based environments. Stability is crucial for preserving the integrity of its arbutin and polyphenol fractions.
