they frequently lack appropriate specificity, chemical stability, or interference resistance to cellular components [115] and they are mostly incapable of simultaneously quantifying the intricate network of interconnected redox couples (e.g., GSH/GSSG, NAD/NADH, and Trx redox states) with adequate sensitivity under physiologically relevant conditions [116]
Clinical research shows that concentrations within this range are effective for increasing collagen production, reducing wrinkles, and improving skin tone without causing irritation
GSH is on the front lines of your defense against free radicals, which are the DNA-damaging compounds found in pollutants, cigarette smoke, and sun overexposure
