the name for those red bumps called pimples that a lot of kids and teens get on their
skin. When your
skin's oil glands make too much oil, the tiny holes on your skin called pores get
stopped up with oil, dead skin, and bacteria. Then the skin around these clogged pores
can swell and look lumpy or red. Usually, this happens during puberty,
when your body is changing from a kid into an adult.
