This has been done many times and the end result is the same, hence the phrase 'beauty tax', and the unsurprising result. You can attempt to explain it away or say 'it doesn't bother me, etc. But what you are doing is taking real data and saying this doesn't matter for half the population, when it is actually important, as important as any gender imbalance, racial disparity, or discrimination due to disability (and yes, they are different things, but none of those things should try to be passed of with a comment of 'it doesn't bother me!' It should bother people, because while it may not bother you, you are an individual, and these results speak to how a group will be perceived.

It's great that you are excellent at putting on makeup in 10 minutes. It's great that you don't mind putting on 10 minutes of makeup x 365 days a year. Which is, btw, 3650 minutes, which translates to 60.8 hours (per year.) That's 2 and a half straight days of putting on makeup a year. If you didn't have to put on any makeup, what would you do with those 2 and a half free days? Vacation? Movie marathon? Laying with friends at the beach?

Sounds like it sure is a tax. You can rationalize it, and many of us do, but the fact of the matter is, in a professional setting, you are treated worse if you do not do many of these things. And what also goes unsaid is that women are often judged and promoted on many aspects of their personal appearance, down to minute details that are not demanded of men.
