Cysteine
Antioxidant
Antioxidants inhibit oxidation, or a chemical reaction that leads to cell-damage and are found to correct signs of aging, brighten skin tone, and some antioxidants help stimulate collagen.
Explained
Cysteine is an amino acid found in our bodies. It becomes an antioxidant when converted into gluthatione.
Once it becomes gluthatione, it prevents oxidative damage to parts of our cell. Gluthatione has also been shown to protect our skin from UV-B induced damage.
