Non-comedogenic

A product that has been specially formulated to ensure it does not clog pores.

Sometimes comedones (blackheads and whiteheads) may form following physical blockage of pores but more often the reason is related to other factors including how much sebum is produced by a person's skin.

Whiteheads

Created when pores become clogged and blocked with oil secretions and dead skin.

Blackheads

These are clogged pores that remain open and trap dirt.
