The kojic acid face wash that I have always trusted, gets rid of dark spots caused by acne, age spots, freckles, and sun-damaged skin. Kojic acid was discovered in Japanand is known for its excellent whitening and antioxidant properties. How to use : Apply it directly to the hands, or on a wet towel, loofah, or bath brush. Just add some water, then work up a lather. Apply it on the body and then rinse it well
