Science
Mechanism of Action
This ingredient functions as a physical abrasive. Upon application, its finely milled particles mechanically remove superficial dead skin cells from the stratum corneum. This action aids in promoting cellular turnover and refining skin texture through physical exfoliation.

The Formula
Formulation
Stability
The powder is prepared from the rind of the araucaria nut, finely ground and sieved to achieve a particle size less than 500 µm. As plant fibers constitute the shell, they are inherently hydrophilic. This characteristic may present formulation challenges, particularly when combined with hydrophobic substances or in environments susceptible to moisture damage.
Conflicts
- Potentially incompatible with hydrophobic substances due to its hydrophilic nature.
Safety
Safety Profile
No specific safety assessments from CIR, SCCS, or FDA have been found for ARAUCARIA ANGUSTIFOLIA NUT SHELL POWDER. While general safety claims exist for araucaria 'seed extract' in cosmetics, these cannot be directly extrapolated to the shell powder form, warranting further specific evaluation.

Verdict
While this ingredient serves as a mechanical abrasive for exfoliation, a comprehensive understanding of its safety profile and specific skin compatibility for the powder form is currently lacking.
