Just take a few spoonfuls of yogurt and a spoonful or two of sugar (don't mix the two until right before you use it, the sugar will dissolve). Then towards the end of your shower mix them together and lightly massage in circles on your face. The sugar helps to loosen dead skin cells and dry flakes and the yogurt also helps with skin cell turnover and moisturizes.
