That means there is nothing to open up the pore itself; and that means the pore is a great place for oils, dirt and bacteria to get clogged.You can get zits anywhere vestigial follicles become clogged.The big culprit on faces, though, isn't dirt so much as an internally-produced substance called sebum that makes the skin cells shed inside the pores.These dead cells, unable to flake away, collect until they become an irritation to the pore.At this point the body reacts in a miniature version of the way it deals with any other invasion: it sends white blood cells to the site to attack the invading body.The result is a mild inflammation at the scene of battle. That inflammation is the zit.So evolution, while having cleaned our hairy faces, gave us pimply skin instead.
