It is not known if acne was present in prehistoric times, as there is no direct evidence of this. Acne is a common skin condition that is caused by a variety of factors, including hormonal changes, bacteria on the skin, and the production of excess oil. These factors may have been present in prehistoric times, but it is impossible to say for sure whether or not they would have resulted in acne. In modern times, factors such as diet, exercise, and pollution can also contribute to the development of acne, but it is not known if these factors were present in prehistoric times.

I'll add anecdotally as someone with oily skin and still deals with acne in his late 30s:

Ironically the more dust I'm exposed to, like if I spend a week on a big yard project and am constantly kicking up dusty dirt and end up golden brown at the end of each day, the more under control my skin gets. It's possible that oily skin is a trait that was meant to deal with a lot more dirt and dust in the immediate environment.

Anecdotally, my over-2 decade long acne problem vanished when I was travelling through places that were sparsely populated / had little pollution. These were modern western societies and I didn’t exactly eat healthy… but the environment was clean. I didn’t wash my face with face wash then as I ran out along the way and didn’t get more. When I travelled through cities a few zits would pop up, but then go away again when I was back in less populated areas.

Anecdotally, I have the opposite experience to you. The more dust I'm exposed to (lawn mowing dust, soybean dust/dirt, wheat chaff, etc) the more likely I am to get blackheads and zits.

Is that because you had to wash your face of dust every day, increasing the frequency of washing? Or do you think the dust helped absorb the oils?

There may be a different cause to this. UV exposure definitely reduces the quantity and frequency of acne, so if you're spending the whole week on a big yard project, it might be the sun rather than the dust.

No doubt it helps, but last time I spent a week rafting in very clear sunny weather and I was still having issues. It's probably a combination because being outdoors by itself was never enough to reel it in. Same thing happened in my teens when I worked construction for a summer, would come home dusty as hell and my skin was the clearest it had ever been all summer long, but all the time I spent hours outside playing various sports had little effect on my skin.

I think I just have really oily skin.
