Use of tissue water as a concentration reference for proton spectroscopic imaging
But for the right patient, in the right protocol, it can meaningfully support antioxidant defences, hydration, recovery and the underlying biology of radiant skin
While IV and oral NAD+ therapies can boost systemic levels, topical application offers a targeted approach delivering NAD+ precursors like niacinamide and NMN directly to the skin, where energy production, DNA repair, and antioxidant defense are most needed
Relevant to the central role of GSH, glutathione peroxidase 4 (GPX4) plays an additional protective role in catalyzing the reduction of organic hydroperoxides, and lipid peroxides in membranes
Enhanced angiogenesis could speed this compensatory process
Another GSH analogue approach is cysteine-substituted S -nitrosoglutathione [95]
