While some people think there's a major body wash and soap difference, this isn't actually the case. The main way they differ is in appearance, although many body washes are formulated with additional moisturizers that combat dryness. That said, body washes might contain harsh chemicals, so be sure to select one that's enriched with hydrating ingredients. For example, Aveda's Cherry Almond Hand and Body Wash contains Babassu Nut, Cherry Blossom, and Sweet Almond Oil. The non-drying formula cleanses while replacing the body's natural oils.
If you prefer a soap bar, check out the Rosemary Mint Bath Bar, which also lightly exfoliates skin to leave it radiant and soft. One isn't necessarily better than the other; it mostly comes down to preference.
