Science
Mechanism of Action
The powder acts as a physical abrasive agent that mechanically disrupts the intercellular bonds of the outermost layer of the stratum corneum. By utilizing controlled particle friction, it sweeps away surface impurities and dead keratinocytes, promoting immediate skin smoothness and enhanced light reflection.

Dusting Analysis
As a physical scrubbing agent, its presence is dictated by desired texture and grit level rather than biological activity at low concentrations. It is rarely 'dusted' because its physical presence is immediately detectable by the consumer.
The Formula
Formulation
Stability
Highly stable and insoluble in both water and oil phases. Efficacy is highly dependent on precision milling and sieving to ensure uniform particle size and avoid jagged edges that could cause micro-tears.
Synergies
- Humectants
- Surfactants
Safety
Safety Profile
While generally non-irritating, individuals with known nut allergies should exercise caution due to potential cross-reactivity with hazelnut proteins. The CIR currently lists data as insufficient regarding specific sensitization profiles for the shell derivative.
