Low Charisma doesn't necessarily mean you are ugly (though it might show as ugly). It can mean that you just don't know how to take care of yourself, dress in bad combination of clothing (tangerine top with fuschia pants), hair is messy, you smell bad because you don't shower everyday (or twice a day as some people need to due to jobs, heat, etc.), are regularly covered in some sort of grime, or, look good but are shy or come off as rude / short without meaning too. (It sounded fine in their head but when said outloud, came out sounding completely different.) it could be hormonal (your body's musky scent is more acidic than other people's). Just a thought.
I think Issac made a good quote I think on Charisma (About how convincing you are). Someone can be an asshole but know the right things to say or the right tone to say them in. Doesn't make them less cold, just, better able to sell ice to Eskimos.
I can be wrong since I am still learning things about the game, but I don't think Perception's 'Outlook' is if you like life or hate life (that's more an RP point) but more literally "see"? As in, how much you see / how far you can see (It does mention 'measure'). Awareness would be something like, noticing a spider on the wall or a smell coming from something or someone. But Outlook could be (could) how much you see overall. That's how I've taken it at least because Liking or Hating people and / or life is more a personal RP point. :)
the relative measure of a persons general awareness
Awareness (AWR) is a measure of a person's ability
to notice things.
Outlook (OUT) is a measure of how a person sees
