Science
Mechanism of Action
It functions as a competitive phosphodiesterase inhibitor, increasing intracellular cyclic AMP, and as an adenosine receptor antagonist. These actions suggest potential anti-inflammatory effects and, through derivatives, the ability to suppress wrinkle formation and UV-induced skin damage.

Dusting Analysis
No specific data suggests Xanthine is commonly 'dusted' in cosmetic formulations; its direct topical use is not widely documented.
The Formula
Formulation
Stability
Xanthine is poorly soluble in cold water but significantly more soluble in hot water. No specific optimal pH range for its stability in cosmetic formulations has been reported.
Safety
Safety Profile
While CIR has reviewed and deemed safe many Xanthine derivatives, Xanthine itself lacks a specific safety assessment. High concentrations may pose a risk for allergic reactions with topical application.

Verdict
Despite its role as a precursor to beneficial ingredients, there is insufficient direct data on Xanthine's specific efficacy and safety in cosmetics to provide a definitive rating.
