Specifically, the ROS H 2 O 2 oxidizes Fe 2+ to Fe 3+ via the Fenton reaction, forming the highly active hydroxyl radical (OH), inducing oxidative stress and leading to ferroptosis, the accumulation of lipoid-OOH, and the oxidation of polyunsaturated fatty acids (PUFAs) (Kehrer, 2000
Oxidative stress biomarkers (MDA, 8-isoprostane, GSSG/GSH ratio) show your baseline antioxidant burden
This is actually a safety feature: it creates a built-in ceiling
Peptides themselves are short chains of amino acids that act as signalling molecules throughout the body, influencing everything from hormone production to tissue repair
It starts getting delivered to the skin cells first and then from there, it transports the rest of the body through the cells
