This mysterious ingredient is the rice powder. Not only that it has UV protective properties, but also whitening and exfoliating ones, which makes it a perfect ingredient for a post-summer procedure when you have to refresh your sun-kissed skin.
You can use it alone, but it will be easy for you to rub the skin area if it is a paste, so, you can add a little bit of mineral water until you get a thick paste. Other matching ingredients are the yogurt, milk and even honey.
Apply the paste to the skin area, let it work for 10 minutes or until it dries out and then rinse with lukewarm water. Easy!
