Thus, it results
in the formation of pimples or acne.

Causes of Acne:
One of the most important causes is the increase in the male hormones
(androgens) that occurs in boys as well as girls during puberty. These
hormones cause an increased production of sebum (oil) and hence result
Hormonal changes related to pregnancy or such changes caused by starting
or stopping birth control pills can also cause acne. Another factor is
heredity or genetics; there is evidence to support the fact that the
tendency to develop acne can be inherited from parents. Apart from this
certain drugs, including androgens and lithium, are also known to cause
acne. Greasy cosmetics may cause further plugging of the follicles in
the skin and hence can precipitate the onset of acne.
Majority of people who develop acne are between the ages of 12 and 25.
For most people, acne tends to go away by the time they reach their
thirties; however, some people in their forties and fifties continue to
have this skin problem.
