Bb is lazy cream. Originally, it was not a makeup product, but an ointment used to repair scars in medical care. Later, it was improved by Koreans into a base makeup product that integrates positive color, concealer, uniform color, sun protection and moisturizing. Foundation is just a simple function of even skin tone.

BB cream is generally lighter than liquid foundation. In fact, it is a combination of N and liquid foundation, which is a lazy practice.
