The regen of course slows down the car, it can not work other way according to the laws of physics (you take away the kinetic energy of the car and transform it into electricity). It helps to the brakes because you don't need that much braking power from the brakes alone (and therefore you also don't heat them that much).

When you drive an EV you don't need brakes at all for common gentle braking.
