Or they need more gentle body wash.

Realistically, most face wash products just (typically “sensitive skin") body wash diluted enough to work in a foaming dispenser.

Pro tip: Check if your face wash manufacturer makes a body wash with the same ingredients. If so, it’s pretty good odds you’re paying 5x the price/oz for something that’s diluted ~2:1 with plain water - so 15x the price of the actual cleaning priduct just to not have to dilute it yourself.
