Why do humans get acne? A hypothesis. (2020)

The first sentence of the abstract is already incorrect—acne is not a disease unique to humans at all.

I don’t have a full list of species that get acne, but I know that cats can get it (Sphinx cats are particularly prone to it!

If the very first sentence is wrong, I question the rest of them.

All monkeys (except for one species) do have hair all over their body. It is very useful to protect their skin from external influences like cancer causing UV radiation and heat/cold. So it is not at all surprising that humans have some unique skin diseases.

Lubrication is not going to help if you try to fix an object that is too big into a small hole. There are so many lubricants involved in a child's birth that it seems pretty unlikely that the child's skin could offer a real benefit.

I am not a fan of TL;DR but this article is BS.
