Kids bath bombs are generally formulated similarly to adult bath bombs but with special consideration for young, sensitive skin. They often contain baking soda, citric acid, and essential oils. Manufacturers might add colors, fragrances, and moisturizing agents like coconut oil or shea butter to enhance the fun and skincare properties. It's essential to look for products that use non-toxic, hypoallergenic, and natural ingredients to ensure they are gentle on your child's skin.
