If I were to reject/break up with a girl because she didn't have perfect skin, I'd be quite the hypocrite. I break out every now and then, since I have oily skin (thanks, Italian genes!). And my breakouts are the nasty cystic kind that takes weeks to fully go away. I have it mostly under control now, but sometimes I break out, especially when I'm under prolonged stress.
If her acne were totally out-of-control, it would be a completely different story. But if she has slight, or even moderate acne, it really wouldn't be the end of the world at all.

Your problem isn't how old these guys are. It's that they're shitty human beings. I bet their acne was just as bad if not worse than yours.
If you wouldn't break up with a guy because of his acne you have the right to expect the same from him.
