Indeed. Living in a third-world country makes it really obvious that while beauty is rooted in nature it can very easily be bought if you have enough money. As you age, the niceness your skin is inversely correlated to solar exposure and manual labor, and positively correlated with money spent in moisturizers and other products. How fit your body is also depends on the money/time spent on a gym and on the quality of the food you eat. Your hair will also look as nice as the money you spend on it (even if you're bald), and even teeth can be fixed if you have enough money at a young age. Finally, beauty is socially defined, and over time the standards will shift to mirror other aspects of society (in Brazil, for example, white people are generally better off, so all standards of beauty encourage "looking white", by hair straightening, makeup, etc. In places where rich people don't do manual work and stay indoors all day being pale is considered pretty, while in places where rich people can afford to go to the beach looking tan is considered better).

In addition, a considerable component of beauty depends on your state of mind and who you are as a person, i.e. how sensitive, how alert, how calm, how happy you are. This effects your eyes, the way you smile, the way you hold yourself and the way you move.

And thus appearance is influenced by your worldview, moral choices, etc.

Some call it 'charisma', which sort of implies that it is a lottery win, like having good genes, but it really isn't.

Great point. Some of the most attractive people alive aren't beautiful. See the entire genre of Rock & Roll for sources.
