Makeup is used on actors in movies to highlight parts of their face like eyes and lips. Or to conceal flaws on their skin that the camera will see. That is called corrective or beauty makeup. Makeup is also the term used to make an actor look scary, bloody, older or injured. I'm sure you watched the rest of the video where Wagner explained that.
Makeup is also the term used to make actors into creatures; like the Frankenstein Monster, the Mummy and the Werewolf. Even aliens from another world.
He means that the art of makeup can turn actors into something very different. That makeup in the moves is much more than "beauty" makeup.
