Well, I definitely agree. Surprise? LOL But unfortunately, I think they'd still have to at least use cover-up on him. I've seen photos of Welling where he clearly wasn't wearing *any* make-up and he still had that naturally flushed look in his skin. The interviewer from Rolling Stone commented on that, as well as somebody who met him on Martha's Vineyard last year, I believe.
That said, people who meet Welling in person also comment on how much older he looks IRL, not to mention how big the man is, so you have a valid point, Zing. Make-up isn't just used to cover up blemishes and make actors look good on camera, it's used to make them visually appear to be the characters they portray, and unless the actors are playing themselves (Bruce Willis in Ocean's Twelve, for example), then it's the make-up folks' job to convincingly transform actors like Val Kilmer into Jim Morrison, Pierce Brosnan into James Bond, or Tom Welling into Superman.
