Bacteria and oil.: Propionibacterium acnes is a bacteria that lives in the oil/hair glands on your face. Excess oil production under the influence of male hormones feeds the bacteria which thrive and cause the local inflammation.

A mix of factors: A particular bacterium, extra sebum at puberty, a male teen having extra keratin. Diet, sex, lifestyle, hygiene are not factors, and touching the lesions is a minor one.
