Your skin is your largest organ, and cleaning this barrier between you and your environment is important. But it's challenging to know which product to use for each body part.
The reason we need soap is simple: to clean. Your grandparents probably had a small selection of bar soaps to choose from, but today, you can clean your body with bar or liquid soap, exfoliate your feet with a scrub and wash your face with a cream cleanser -- all during the same shower. The key to finding a body wash or cleanser that's right for you is to understand their ingredients and what they can do for your skin.
