Dr. Lefkowicz also finds body washes to be slightly more hygienic than Bath Bars. That's because bacteria can live on bars and remain on there from shower to shower and person to person. "To avoid bacteria buildup, always rinse it between use and allow to drain and dry completely," Dr. Lefkowicz adds. "With a body wash, it is easier to avoid bacteria buildup since it doesn’t touch skin while in the bottle."

What is the difference between shower gel and body wash?

They are similar, but not identical. Both are liquid cleansers, typically made with emollients to soften the skin and mild surfactants that create a rich, foamy lather. The main difference is in their consistencies and concentration of ingredients. “Shower gel has a firmer, gel-like consistency, and typically has a higher concentration of fragrance," Dr. Lefkowicz says. "Body washes tend to be more hydrating and moisturizing, which makes it more useful in harsher, colder weather to help avoid stripping moisture away from the skin, which can open it up to damage."
