So, here's the question: what's the evolutionary explanation for acne? What, if any, selective advantage did acne (or something that causes acne) bestow to its possessors?
I've compiled a short list of possibilities that I'd like for you to help me expand.

Whites have more acne than non-whites. So, how come? Well, I've thought about this for a bit since a close friend of mine suffers from Rosacea (a reddening condition of usually the face). Whites are white to absorb solar radiation to synthesis stuff like Vitamin D. We feed off the sun. The farther north one gets and the more clothing you wear means the whiter we need to get to make enough Vitamin D. There's another strategy evolution can use, though - don't just make the skin whiter, fill it with more blood. Is it possible that whites get more acne because our facial skin is flusher because it's trying to get enough blood to the surface to make Vitamin D? Maybe. It's a thought.
prevents us from getting murdered. The argument simplistically goes like this, if you look good, you're a threat to other males' harems and therefore you get killed. On the other hand, if your face looks like the surface of the moon then you probably aren't a threat for their mate to cheat on with. Or, so they think! This argument receives anecdotal support by a good number of monkey species that have beta and omega males producing more offspring than alpha males. Zits are the perfect cover to sneak a mate with or to survive until your fully grown.
Both of which have been linked to increased levels of acne. The study in the linked article talks about tribal Canadians and Japanese that broke out after being introduced to dairy. It also talks about aboriginal people from Paraguay and Papua New Guinea that ate hardly any complex carbs and likewise had no occurrences of acne. Now, I should say diet and acne is a highly debated subject, but one I think we should listen to.
