What Are Whiteheads?
Whiteheads--one of the components that make up the general topic of acne--are white bumps that appear on the face and forehead. These bumps are the product of oils and dead skin cells getting trapped in the facial pores. If bacteria mixes with this combination, it can cause what's known as cystic acne. While whiteheads by themselves pose little threat (other than a temporary cosmetic blemish), cystic acne can result in permanent scarring, so it is always important to wash with an anti-bacterial soap, particularly if you are prone to whiteheads.
Causes
Ironically, excess exfoliation is the most common cause of whiteheads, despite what many television commercials and skin products would have you believe. This exfoliation is usually done on a natural basis by the body, but the problem can be accelerated by using OTC exfoliates.
Some scientists that believe certain people are prone to producing an oil which is drier than usual, perhaps explaining why it so easily gets plugged up into the pores. Oleic acid is also a cause of not only whiteheads, but other forms of acne as well.
Prevention
A good cleansing regimen is the biggest step of prevention anyone can take. Cleaning daily with an anti-bacterial soap can do wonders for keeping oils from collecting on the skin and in the pores. However, cleaning can be a double-edged sword. You don't want to overdo the cleaning (such as washing your face two or three times a day), as this can actually dry the skin out and cause your body to produce even more oil than usual. This would have the opposite effect and possibly cause more whiteheads to appear. Oil-based makeup should also be avoided by those who are prone to whitehead breakouts.
