Combining the effects of the papaya with kojic acid gives a sort of dual action when it comes to lightening skin tone. First off, the papaya ingredient gets to work by exfoliating the skin and removing dead skin cells and dirt. This will help show newer and softer skin that is naturally lighter than before.
