What Cause Acne?
The pores of your skin contain sebaceous
glands that release oil called sebum. Acne occurs when your
pores become 'clogged' with sebum, dead skin cells and bacteria.
A whitehead may appear when the clogged pore closes and then
bulges out. If the pore remains open then the top may darken
resulting in a blackhead.
The walls of a pore can become damaged
which allows bacteria and dead skin cells to work their way
under live skin cells, this causes a small infection with
redness and pimples. If the clogged pore is deep within the
skin then the infection may become worse and eventually result
in a cyst.
Most people experience acne during
adolescence when the hormone testosterone increases the amount
a sebum production. However, it is not uncommon for some one
to suffer from acne well into adulthood even if they had 'perfect'
skin as a teenager.
