Solid sugar scrubs have all the same exfoliating benefits, but they’re a little easier to handle. They also look super cute! This recipe is made with watermelon oil, sugar, and melt and pour soap base. The bars come together in about 15 minutes, and they're ready to use or gift once they're fully cool and hard. To use, warm the cube in water and then break it apart in your hands. Apply to damp skin. The cube will lather, scrub, and moisturize all at once.
