Introduction
Acne is a common skin complaint. Predominantly a curse of Adolescents and teens, it is currently the most
common skin condition in North America with approximately 70 to 87% of teens being affected and 20% of its
cases been linked to adults. Whilst acne doesn't necessarily affect everyone, around 17 in every 20 people are
afflicted in their lifetime. Usually affecting areas on the face, neck, back and the chest, acne can be seen most
prominently in teenage boys whom commonly have the worst cases, whilst in adult women the condition is most
noticeable.
There are varying type of acne, which can range from mild to cystic. Whilst it can take many forms, such as
whiteheads, blackhead, papules and pustules, acne is and of itself a distressing condition. Acne is caused when
the hair follicles in the skin become clogged with dead skin cells and the substance sebum (oil) forms a plug in
the pore where bacteria can flourish. This is known as a comedo. If left untreated, a patient may notice an
increase in the number of pimples they have, and can even be affected by scars and dark skin patches as the acne
fades. Clogged pores can even become infected, causing the skin around the plug to become inflamed and sore.
The resulting irritation can be very painful in some cases, as it is a response from the bodies immune system to
fight the bacteria, which sends more blood and chemicals to the affected area in a bid to clear the infection but
which also causes inflammation.
