L‐Cysteine stimulates the production of glutathione. Glutathione is an antioxidant that exists in the body and is very useful in preventing the production of melanin. Therefore, not taking enough L-cysteine can result in various skin troubles.
L‐Cysteine has an antioxidative effect. It stimulates the activity of glutathione peroxidase enzymes, which protect the skin from reactive oxygen species (ROS). It also represses the activity of tyrosinase enzymes, which come from ROS and are involved in the production of melanin.
L‐Cysteine activates your skin’s turnover, which is directly related to wrinkles and skin darkening. It helps your body’s metabolism, making it easier to flush out melanin pigments.
