How often should I use facial cleanser?

If it is oily skin, it is enough to wash your face with facial cleanser once every morning and evening, because washing your face with facial cleanser too often will destroy the oil-water balance of your skin, make your skin fragile and easily lead to other facial skin problems.

If it is dry skin, just wash it with facial cleanser once every night, and the facial cleanser used must be mild, so just wash your face with clear water in the morning.
