When do boys start shaving their face?

As they go through puberty, boys will grow so much hair on their face, that they may decide to start shaving. Usually a few years after they hit puberty which is between the ages of 12 and 15. They might start but it varies between people. This is because everyone is different and some boys go through puberty very young while others get it when they're older. i started shaving my uper lip at 13 years old i think there is no basic age set to shave i think boys shouldshave when ever they want to shave.
