Science
Mechanism of Action
This ingredient physically abrades the skin's surface, leveraging its particulate structure to effectively slough off accumulated dead epidermal cells. This action promotes cellular renewal and leads to a visibly smoother, softer complexion. Any secondary cosmetic benefits, such as anti-inflammatory or antimicrobial effects, are likely attributable to the trace amounts of essential oil components naturally present in the shell material.

Dusting Analysis
As a functional physical abrasive, Santalum Spicatum Shell Powder is incorporated for its textural and exfoliating properties. Its efficacy is directly tied to its physical presence and concentration, making typical 'dusting' analysis for active ingredients less relevant.

Stability
As a particulate powder, Santalum Spicatum Shell Powder is generally stable. However, when formulated into cosmetic products, especially aqueous environments, the stability of any minor residual oil components within the powder should be considered.
