Start out like you normally wash your face; wet it, take a pump of your facial cleanser, and rub it on your face. Next (without rinsing your hands) put a teaspoon or two of sugar on your fingers and rub it all over your face. Rinse. You get the awesome exfoliation of the sugar while also cleansing your face. I do this trick a few times a week and love the feeling of clean, exfoliated skin!
Tip: To make it even easier, I keep a small container of sugar and a scoop in the bathroom so I don't have to run to the kitchen every time I want to exfoliate!
