Actually, saying some skin types "can't handle the heat" is a big assumption. Steam opens pores deeply which is key for a real clean-out, and cool mist often just sits on the surface. The problem might be using too much heat or not checking a client's skin first. For a lot of people, especially with congestion, skipping steam means you're not getting the full benefit. A quick test spot tells you more than writing off the whole tool. Proper technique with steam beats avoiding it altogether.
