This kind of thing is not true or false, only good or bad. Facial cleanser mainly depends on whether it hurts the skin. Take a silverware and put some facial cleanser on it. Draw it on white paper. If it is black, it means that the facial cleanser is lead and mercury. There is also a misunderstanding of most consumers, that is, the more foam in facial cleanser, the better. It's actually wrong. Facial cleanser will only foam if it is used for oily skin and mixed skin. Like dry and medium dry, no foam. Because this kind of skin is more suitable for mild facial cleanser.
