They're kind of whatever. I mean, I have pretty bad dark circles so I can't complain. Obviously they're not especially attractive, but I don't find them that unattractive either. Actually, there's this one guy (Miles from the show Work of Art, fyi) that always has really prominent dark circles, and I think it adds to his attractiveness, kind of? On him (and several other guys I know) it actually makes them look kind of adorable. So I don't really mind.
Those aren't even bad at all. They're not a deal breaker at all, that'd b kinda crazy if they were for someone lol A lot of under eye circles are hereditary so If he can't make them go away then... he can't. Its not biggie. I'd still date the guy .. nd maybe advise him to get some rest :-p
can make guys a tiny bit less attractive, but really not a big deal, even in the looks department. definitely not a deal breaker! besides, I have them too, and even though I try to cover them with makeup sometimes I don't. So they're barely even a blip on the radar.
It may come across as slightly metrosexual, but there is concealer for men as well. A little dash here and there won't hurt. Just don't lather it on like you were basting a turkey with some sort of marinate.
