I use two the same as Aude does. Except that I do use sugar mixed with my cleanser to wash my face. I use very little, maybe a teaspoon or less very gently and it leaves my skin super soft. I use salt for my elbows, knees and feet too as it's a bit more abrasive than sugar and it doesn't dissolve as quickly. In the summer I use salt with olive oil all over my body lightly, in the winter I use sugar mixed with olive oil instead. I haven't tried baking soda as a facial exfoliator yet but that's bc I keep forgetting even though the sugar, salt and baking soda are right next to each other lol.
