What is Acne?

Acne is a skin disorder resulting from the action of hormones and other substances on the
skin’s oil glands (sebaceous glands) and hair follicles. Skin pores become blocked resulting in
outbreaks of lesions known as zits or pimples. Acne usually occurs on the face, neck, back
shoulders and chest. Normally acne not a serious health problem, severe acne can result in
permanent scarring.

How does Acne develop?
Doctors describe acne as a disease of the pilosebaceous units (PSUs). Found over most of the
body, PSUs consist of a sebaceous gland connected to the canal (a follicle) that contains a fine
hair. Sebaceous glands produce an oily sebum that normally empties onto the skins surface
and blocks the pores.

What causes Acne?
The exact causes of acne are unknown however doctors believe it results from several factors.
Which are as follows:

• Increase in hormones called androgens (male sex hormones)
• Hormonal changes related to pregnancy.
• Genetics or heredity
• Greasy cosmetics (clog the pores)
• Sweaty sports equipment such as a sports helmet
• Pollution and humidity
• Stress
• Hard scrubbing of the skin

Acne Myths?
Greasy foods are often blamed for acne but there is little evidence to link this to acne in most
people. Another common myth is that dirty skin causes acne however acne lesions and
blackheads are not caused by dirt. Stress does not cause acne, however research suggests that
for people who have acne stress makes it worse.

Who can get Acne?
People of all ages and races get acne though it is most common in young adults. An estimated
80% of all people between the ages of 11 and 30 have acne outbreaks at some point. For
most, acne will stop by the time they reach their thirties.
