This was not the question

But drugs also mean nothing without training to take advantage of the chemical boost

I mean that sports are a contest of skill and natural ability, where drugs are considered an alteration of natural ability factors (and also have long-term detrimental health effects). In contrast, the natural ability part of a beauty contest is self-evident, but the “skill” portion of the competition comprises not only clothing and performance but also the application of cosmetics and hair products - which are at least in contemporary times minimally harmful. In other words, the difference is in both social context and safety.
