Mechanism of Action
Deoxyguanosine is an integral component of DNA. Upon oxidative stress, particularly from UV exposure, it can be oxidized to 8-hydroxy-2'-deoxyguanosine (8-OHdG). This oxidized form has demonstrated antioxidant capabilities by actively inhibiting the production of reactive oxygen species (ROS) and downregulating the expression of matrix metalloproteinases (MMPs), thereby suggesting a protective role against UV-induced damage within the skin.

The Formula
Formulation
Stability
Deoxyguanosine exhibits stability in aqueous solutions within a neutral pH range of 7.01-7.4. It is slightly soluble in water and highly soluble in DMSO (100 mg/mL). For formulation into both aqueous (e.g., saline) and oil-based (e.g., corn oil) systems, co-solvents may be necessary. Dissolution can be enhanced through heating and/or sonication.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not assessed deoxyguanosine for cosmetic use, nor has the SCCS. PubChem lists 'Irritant' as a primary hazard for the raw chemical, indicating a potential for irritation, though no specific safety assessment for its use in cosmetic formulations is available.

Verdict
While its oxidized derivative, 8-OHdG, demonstrates potential in safeguarding skin from UV-induced oxidative damage, the absence of dedicated safety assessments for cosmetic use and clinical data for deoxyguanosine itself warrants further investigation before definitive recommendation.
