Science
Mechanism of Action
This extract operates primarily as a tyrosinase inhibitor, blocking the rate-limiting enzyme responsible for melanin synthesis to treat hyperpigmentation at the source. Its rich profile of flavonoids like quercetin and phenolic acids such as ferulic acid scavenges free radicals, while its ability to downregulate pro-inflammatory cytokines helps stabilize the skin barrier and reduce reactive sensitivity.

Key findings
- 01 In vitro and clinical trials confirmed that twice-daily application over 8 weeks significantly inhibits melanin synthesis and visibly enhances skin radiance.
- 02 A 2% concentration demonstrated a 35% reduction in reactive oxygen species (ROS) in human keratinocytes following UV-induced stress.

Dusting Analysis
Because it is a premium 'callus' (stem cell) extract, it is frequently used in 'label dusting' at concentrations below 0.5% for marketing claims. However, clinical data suggests a minimum of 1.0% is required for measurable brightening and 2.0% for significant antioxidant protection.
The Formula
Formulation
Stability
Maintains high stability in aqueous solutions and oil-in-water emulsions. It is thermolabile and must be incorporated during the cooling phase below 40°C to prevent degradation of phenolic compounds.
