Acne is a common skin disease that
affects most of people at some time during their lives. Acne is most common
in adolescents although for some people it may only first appear in their
mid twenties and can even persist into middle age.
What is acne?
Our faces and bodies are covered with tiny hairs that fit into a hair
follicle, or 'pore'. Deep within these pores are glands that produce natural
oil called 'sebum'. Sebum's function is to keep the skin lubricated and
prevent it from drying out.
Acne occurs when the oil glands respond abnormally to levels of the male
hormone testosterone. Excess oil is produced which combines with dead skin
cells on the top layer of the skin. A sticky mixture is formed which blocks
the skin pores, trapping oil and bacteria inside. As the oil glands continue
to produce excess oil the follicle begins to swell producing blackheads,
pimples, spots, and whiteheads.
Acne is more common among teenagers because it is only with the onset of
puberty that the body begins to produce hormones.
Scarring
People often squeeze spots and blemishes because of their unpleasant
appearance. This can however cause increased inflammation and in extreme
cases lead to permanent scars of the face.
