I think in the comics he did start aging eventually. I think there was some something or other involving either one of the flashes or one of the magic users that kickstarted his aging. There's probably somebody on wiki who can clear it up.

Of course, he could just be not showing the aging due to the indestructability thing, aging at a decelerated rate, or maybe he just really doesn't look all that different from one year to the next. The only thing that's changed about my appearance over the past, heck probably seven years is that I've gotten a little taller and a little more muscular. My grandpa did the same thing. The only way anyone can tell what year a picture of one of us was taken is by remembering what color shirt we were wearing. When I'm twenty six, I'll probably look almost exactly like I did when I was sixteen unless I grow a beard or start bodybuilding. Superboy apparently doesn't grow whiskers and he's already built like an ox. Even if he were aging, he always wears the same shirt, coat and hairdo. Even if he was aging, would anybody be able to tell? Somehow I rather doubt it.
