Question

"I'm a love or hate thing for men. I alter the looks and feelings of the cultures. I will go up even higher if a person takes care of himself. I'm going to fool some people. I'm a mystery to others. Some people may want to try to hide me, but I'm going to show. I'm not going to go down, no matter how hard people try. What am I?"

Can't find the answer to this anywhere, and I only have 3 guesses. Any takers?
