That's more of a bumper sticker, than reality. Some beauty is non-physical and sublime. A lot of beauty is physical. A person's soul can be beautiful, and so can a person's physical features. Most of those physical features can, in principle, be cosmetically improved. To say otherwise is simply to be disingenuous.
Cosmetics and plastic surgery sell very well, not just on Halloween, but year round, to people looking to make themselves more physically attractive. Some people fail, of course, but the robustness of the market suggests that most people have developed a certain trust in their ability to not fail. The longevity of the market suggests this must be a real effect, since if purchasers were mistaken in their belief, this market would not have existed for millennia.
Assuming you are sighted, I suppose there is a non-zero (but still unbelievably small) chance that you are nonetheless one of the few people who never found a person using such a cosmetic enhancement more attractive than you would have found them without the enhancement. Beauty is in the eye of the beholder, of course, and subjective, but the experience of a vast majority of people on this planet is that physical attractiveness exists and matters in our personal relationships, and cosmetic enhancements on average work as intended.
One can lament that as unfortunate, but it's the heritage evolution has left us with.
