Science
Mechanism of Action
This extract operates via 'adipocyte browning,' a process that stimulates the conversion of white adipocytes (which store fat) into brown adipocytes (which burn fat for thermogenesis). Beyond metabolic remodeling, it enhances cutaneous microcirculation and reinforces the skin barrier using a rich profile of erucic and oleic fatty acids to prevent transepidermal water loss.

Clinical Evidence

Key findings
- 01 In vivo testing demonstrated an 18.2% reduction in cellulite and a reduction in waist circumference of up to 3.4 cm over an 8-week period.
- 02 In vitro analysis showed a 125% increase in brown fat marker expression, confirming its efficacy in fat-burning metabolic pathways.
Transparency
Dusting Analysis
While it provides barrier support at lower levels, its clinically validated slimming and anti-cellulite benefits require a minimum of 0.33% to 2%. Formulations listing it near the end of the INCI deck often use it for marketing 'claims' rather than functional body contouring.
The Formula
Formulation
Stability
Highly stable in neutral environments; however, the phenolic compounds like sinapine degrade in extreme pH conditions (below 3.0 or above 10.0). Standard extracts are oil-soluble, while hydrolyzed variants offer water solubility.
