Well, when it comes to human beauty. I determine whether someone is beautiful from the vibe that I get from someone. I might talk to them on the phone before I ever see a picture of them and be like, "Oh this person is really good looking." then after I get to see them in real life, silently think to myself, "They could really do with some self maintance."
But, everyone is beautiful in their own way. You should appreaciate what you got. Don't waste your money on it.
