A big pimple appearing on the face the day of a big event is likely to be distressing. Whiteheads appear because the pore is completely blocked. On oily skins, they may appear as part of a problem skin condition along with blackheads, pimples and acne.
Sebum contributes to skin oils and people with dry sebum may have dry skin and this may be especially true of people with chronic whiteheads.
