Glutathione is a natural antioxidant found in the body that helps fight free radicals, toxins, and oxidative stress. When used in skincare products, particularly in soaps, glutathione works to lighten hyperpigmentation, reduce dark spots, and even out skin tone. The Glutathione Skin Whitening Soap 75gm is specially formulated to offer all these benefits in a convenient and easy-to-use cleansing bar.
