Why are pimples concentrated on the face as opposed to being evenly distributed over the body?

In: Biology

Back, ass and chest happen for a lot of people as well. Not me, just saying….actually inside my ass cheeks sometimes. But they’re usually sub-dermal and mad painful. But that’s like one every few years.

As noted by other commenters, pimples _can_ be found anywhere. However, facial skin is oiler than other skin (for a discussion of why, see this discussion: https://www.reddit.com/r/askscience/comments/rsg96/why_is_face_skin_so_much_oilier_than_other_parts/) . Since excess oil & dirt is a major cause of pimples, it stands to reason that your face will be more prone to pimples than other locations.

Pimples are the result of your pores becoming clogged with excess oil (sebum), bacterial waste, or other material like small dirt particles. The pores all over your body have sebum-producing glands called [sebaceous glands](https://en.wikipedia.org/wiki/Sebaceous_gland). These glands are more prevalent in the face and scalp (and non-existent on the palms of hands and soles of the feet). Since the face has more sebaceous glands, you have a higher chance of developing pore blockages in that area.
