Novel Approach to Skin Anti-Aging: Boosting Pharmacological Effects of Exogenous Nicotinamide Adenine Dinucleotide (NAD⁺) by Synergistic Inhibition of CD38 Expression.

ABSTRACT: Nicotinamide adenine dinucleotide (NAD⁺) is indispensable for the regulation of biological metabolism. Previous studies have revealed its role in aging and degenerative diseases, while crucially showing that supplementation with NAD⁺ or its precursors could ameliorate or reverse the progression of aging. Despite extensive evidence for the role and action of NAD⁺ in aging, its pharmacological activity on the skin, or even its mechanism, has not been elucidated. In this study, we established a novel approach to effectively utilize NAD⁺ for skin anti-aging by enhancing the pharmacological efficacy of exogenous NAD⁺ using a phytochemical complex consisting of quercetin, and enoxolone through inhibition of CD38. Through the comprehensive in
