a. eye of the beholder
b. beauty is not a default state of being*, it requires effort. How much effort of entirely up to you, if you like yourself with makeup (and yes this does go for men too) then use makeup, if you don't then don't bother. do you think you'd like longer hair? shorter? colored?
And if you think you're so uniquely ugly as to be utterly sure that nothing you can do will make you happy you may want to interrogate those feelings, there's probably more going on under the surface there.

* this does not mean that someone who is unwilling or unable to put that effort in is "ugly". this is about your perception of yourself. your perception of other is irrelevant unless asked for

I'm sure there's things under the surface, but I don't consider myself ugly or anything like that. I was sort of being dumb with my original reply. But thank you. I really appreciate it.

Never tried makeup, but I always have my nails painted haha.
