Choose your own spa adventure! All-Natural Spa Lab teaches budding cosmetic scientists how to use natural ingredients to make store-quality beauty products, including bath bombs, scented stones, body scrubs, fairy dust, glitter gel, lip balms, masks, and bath salts. These projects and recipes use household materials and custom molds and equipment to create scrumptious-smelling spa treatments at home. The citric acid adds pizzazz to bath bombs, and the cosmetic-grade shimmer powder gives a glittery glow to your products. The science behind the ingredients and formulas is peppered throughout the fully illustrated book.
