Cleansing time

I've heard that it's not good to leave your cleansing time on for too long. Do you all know the exact reason why?

Cleansing is essential for removing impurities from the pores. However, it is said that excessive cleansing strips away the skin's normal natural moisturizing factors, thereby damaging the skin barrier.

If you are wearing makeup, double cleanse, and please finish washing within 3 minutes.

If you don't usually wear makeup, a first cleanse is sufficient, and deep cleansing once or twice a week is enough.
