Glutathione is a naturally occurring compound in the human body that plays an important role in protecting cells from oxidative stress. It belongs to the group of antioxidants, substances that help neutralise free radicals and support the normal functioning of cells.
In cosmetics, glutathione is used primarily for its antioxidant properties. It is most commonly found in products designed for facial skin with uneven tone and hyperpigmentation, as well as in formulations intended to help protect the skin from oxidative stress caused by external factors such as pollution and UV radiation, while supporting a fresher, more even-looking complexion.
