Here's a breakdown of what they are and their characteristics:
* Appearance: Typically small, round or oval shaped, and brightly colored.
* Composition: The outer shell is usually made of gelatin. The inside contains bath oil.
* Function: When added to warm bathwater, the gelatin shell dissolves, releasing the oil into the water.
* Benefits:
* Moisturizing: The oil helps to hydrate and soften the skin.
* Aromatherapy: Many bath pearls are scented with essential oils or fragrances to provide a relaxing or invigorating aromatherapy experience.
* Visual Appeal: The colorful beads can make the bath more visually appealing.
* Ingredients: The oils used can vary and may include mineral oil, essential oils, vitamin E, or other moisturizing ingredients.
* Usage: Simply drop a few bath pearls into a running bath and allow them to dissolve.
While they were very popular in the past, they aren't as common now due to concerns about ingredients, and the rise of bath bombs and other similar products.
