How do you use a Bath Bomb? Bath Bombs are single-use, spherical blends of smoothing, fragrant extracts and oils that you can toss in your tub before bath time. The primary ingredients are sodium bicarbonate and citric acid, which interact with each other once dissolved in water to create that fizzing effect we know and love. Once this reaction occurs, the bath bomb dissolves and breaks apart, releasing all the good stuff inside: from delicious scents to skin smoothing emollients, which act as softeners on your skin. Our bath bombs are vegan friendly, cruelty free and handmade in USA. Make every bath luxurious with our amazing bath bombs, bubble bars, shampoo bars, candles, wax melts, candies, chocolates and much, much more!
