pimples are like one or 2 small pimples spaced out on your face…acne is a group of pimples and its alot worse …im my opinion they are bigger and hurt….pores are just the holes on your skin …some people you can see them more then others…pimples and acne can show up anywhere…but pores some peoples show more around their cheeks near their nose…and on their nose..and between their eyebrows…and some people their pores show ALL over…
