Science
Mechanism of Action
Dyphylline's action is understood to involve competitive inhibition of phosphodiesterase enzymes, leading to an increase in intracellular cyclic AMP (cAMP). This biochemical pathway typically results in the relaxation of smooth muscle tissues, which could theoretically influence cutaneous microcirculation. Furthermore, it functions as an antagonist to A1 and A2 adenosine receptors.

The Formula
Formulation
Stability
A 1% aqueous solution of Dyphylline exhibits optimal stability within a pH range of 6.6 to 7.3. It demonstrates high solubility in water (1 gram dissolves in 3 mL water at 25 °C) and is also soluble in alcohol and chloroform.
Safety
Safety Profile
Dyphylline is primarily regulated as a prescription medication in the US, prescribed for respiratory conditions. There is a notable absence of safety assessments by the Cosmetic Ingredient Review (CIR) or the SCCS for its use in cosmetic products. A chemically related compound, Theophylline, has been prohibited in cosmetic products within the EU as of December 2023, raising significant regulatory concerns for similar xanthine derivatives.

Verdict
Due to its primary classification as a prescription drug, the complete lack of cosmetic-specific safety assessments, and the prohibition of a related compound in EU cosmetics, Dyphylline's inclusion in skincare formulations is highly questionable.
