Acne is a skin condition that occurs when the sebaceous (oil-secreting) glands
in the skin and along hair shafts become clogged and inflamed, and infected by
bacteria.
Blackheads and whiteheads form in the clogged pores. Blackheads are
small, usually flat spots with black centres. Whiteheads are similar, but because
thay are closed, they don't have dark centres. Both blackheads and whiteheads
may develop into swollen, tender papules (pimples) and pustules.

If acne is severe, large pimples – called cysts, nodules or cystic lesions
– form firm swellings deep under the skin. They become inflamed and may develop
into painful lumps; leading to scarring.
Acne is not limited to teenagers. Rarely, babies are born with acne and some
people get acne for the first time after they’ve reached adulthood. Most people
outgrow acne; but in women it may last until the menopause. 5% of women of 40
years of age have acne; but only 1% of men in that age group.
Acne can develop on your face, neck, chest, shoulders or back. The severity
may differ from person to person and may fluctuate over time. Acne often has
an adverse emotional effect on sufferers.
There is no cure for acne, but effective treatment is available. Severe acne requires medical
treatment.
