It's not melasma. Makeup for photo and film should take care of that and even out the skin tone. I've noticed that whenever Tom gets his makeup done by Amanda Grossman, his face is a darker tone than his neck. She tries to "bronze" him up. But when he hires another makeup artist, he never has this uneven makeup problem. When he was doing his CP promo and then was in San Sebastián for HR, his makeup was so much better. When I checked, sure enough he had another lady, Sally something doing his makeup.
