Using sand to exfoliate makes sense because sand is a fine grain that removes dead skin cells with ease and leaves your skin feeling renewed, soft and beautiful. Not only does sand exfoliate, but it’s also excellent at eliminating impurities on your skin. And, when you’re using sand to exfoliate, you’re also improving blood circulation. Improving circulation is an incredible thing for your body because it reduces the appearance of cellulite and combats it from forming.
