Causes &
Myths
Causes of Acne Vulgaris: Although
the exact causes of Acne are unknown, researchers do know that
hormones (the male hormone androgen) and genetics are the main
culprits behind acne vulgaris.
According to Dr. Howard L Sofen, Assistant Clinical
Professor of Dermatology at UCLA , "Acne develops when
the sebaceous glands in a person's skin make extra oil (sebum).
This oil combines with cells that line the walls of these glands
and clogs the person's skin pores."
It is widely believed
that hormones, or actually the male hormone
androgen, can overstimulate the production of sebum in some
people. "These (androgens) increase in both boys
and girls during puberty and cause the sebaceous glands
to enlarge and make more sebum. Hormonal changes related
to pregnancy or starting or stopping birth control pills
can also cause acne." (2)
Girls and young women often see an "outbreak"
of acne just prior to the menstrual cycle. The hormonal
surge can lead to the overproduction of sebum which leads
to more acne.
Genetics, or heredity, can
also play a role. The National Institute of Health states:
"Researchers believe that the tendency to develop acne
can be inherited from parents. For example, studies have
shown that many school-age boys with acne have a family
history of the disorder." (2)

External factors which can cause
acne to be worse include the following:
- Drugs that cause changes or increases in hormone levels.
- Oil from skin care products and cosmetics.
- Cooking oil and greese from working in a kitchen or restaurant.
- Pressure or skin constraint caused by sports equipment, tight
uniforms or clothing, hats, etc.
- High humidity or pollution.
- Hard scrubbing of the skin. Gentle exfoliation is okay though.
Myths about the causes of acne
have become urban legends. The most popular is that greasy foods
and chocolate are to blame. However, there is little to no evidence
that either have any effect on most people.
