Yeah. Simple as this: Acne is a sign that something is wrong with your body. It is a rash caused by underlying conditions.
As far as how it's made, toxins and other crap are pushed through the pores of your skin, and trapped in there as it fills up. You could compare it to puss-filled mosquito or ant bites. inflammation with puss.

The idea of "toxins" causing acne has no basis in scientific fact.
Acne is the result of the sebum (oily substance produced by the skin's oil glands), P. acnes bacteria (which occurs naturally and lives off of sebum), and dead skin cells or dirt, etc. that get trapped in your pores.
Overproduction of sebum and/or dead skin cells result in those things getting trapped by forrming a "plug" in your folicles, which causes the bacteria to flourish = infammation = acne. In properly functioning skin, the sebum should help to carry out dead skin cells, not trap them.
Overproduction of sebum can be caused by a large number of health factors (stress, diet, medical condition, genetics, medicines, hormones, etc.) which is part of the reason why it is hard to know what exactly is "causing" your acne. Too many dead skin cells could be a result of not keeping your face clean or not exfoliating, etc. Irritation of the skin can also cause swelling which increases chances sebum will get trapped, etc. So there are many, many, many possible causes of acne.
